I am concerned with some recent good-faith changes to this article over the past week or so. 50-60 edits have been made in this period, primarily to the lead section. Not only has the section increased in length by over 50%, but I believe that overly technical terms have been introduced and the overall grammaticality has suffered. As it is a Featured Article, I would expect better conformance to MOS:INTRO.

The following sentence, for example, is not very grammatical:

As members of Earth's biosphere, depending on it and Earth's natural resources for survival, humans impact and exploit, as a connected world, unsustainable and degrading Earth's surface, orbits, hydrology, atmospheric processes, and endangering other life, causing mass extinction.

Compare with the same passage from before these edits:

Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's surface, hydrology, atmospheric processes, and other life.

Again, I believe that these edits are being made in good faith. But I fear they risk decreasing the quality of a well-written Featured Article. Fowlerism ( talk) 17:53, 10 January 2022 (UTC)

Hi, thank you for writing on the talk page and being so considerate. Well I agree that the sentances are still too convoluted (I will never pick up a job in literature, I am afraid). But I am working on it. I first tried to introduce a more complete overview of the issues that are relevant for Earth. I have realized how giant Earth as a topic is because of its totality as the home of so many relevant things, acknowledging that alot of complex terms/links have been added to the introduction now. But since I think it is important to give a comprehensive overview of the main topics relating to Earth I am for keeping a rich introduction, but yes a better wording is needed. This I am working on now, as you can see with my last edits, trying to increse text-quality. Thank you again for being considerate. Nsae Comp ( talk) 07:25, 11 January 2022 (UTC)

I don't have the energy to do anything more than comment here (long COVID, boohoo), but I think there are main things that need to be improved

• The readability is extremely low. Hemingway app estimates that this text is suitable for post-graduates. In a broad topic like earth, we'd like to aim for people with 10 years less education.
• The text feels like a wall of blue. There is definitely overlinking in there (we don't need to introduce AE).

Given it's such an important topic, and it has recently gone through a FAR, wouldn't it be better to temporarily return to the previous version and work on a new lead here on talk? My personal preference is always for shorter paragraphs, as those are easier to digest. I think important information is now lost among less important information. Femke ( talk) 17:11, 11 January 2022 (UTC)

• And I now see that there are thing(s) in the lede that are not found in the body (the unnecessary detail of the solar constant), which would make it fail another FA. Femke ( talk) 17:14, 11 January 2022 (UTC)

Following your suggestion Femke, I have restored the lead section to how it was before the recent edits. @ Nsae Comp: please make suggestions here to allow a consensus to be reached on the language and content used in the lead section before restoring any of your edits. Mikenorton ( talk) 17:30, 11 January 2022 (UTC)

I was working on the readability. No one was substantially joining in for a week. As long as no one is considering what I tried to improve and no one suggesting concrete improvements, I am sorry but I am out. You have my final from today, do and participate but I have worked on this too much for this if it is just undone. Ill answer to proper improvement suggestions but an undo just like that makes me just to leave. I am looking forward to your work. PS: you also undid changes that were not about the lead text, also by others; I dont understand why. Nsae Comp ( talk) 19:30, 11 January 2022 (UTC)

PS: I didnt plan to go so deep and long on the lead, but it just happend, so my apologies for the big changes without discussion, but I was and am happy to work together to give readers a good introduction to Earth (the previous/current version is not such a thing, it is a many edits stiched together text lacking in logic and content. That said I did use the original version and just tried to arrange it more logically and detailed. I agree some links can be left out, but thats no effort to do. Nsae Comp ( talk) 19:36, 11 January 2022 (UTC)

sorry for not responding earlier. If you can copy your version to talk, that should allow somebody to combine the best of the two versions. The current text is good in length imo (about 50 words of growth space for my maximum lead length preference). Lack of logic is what would worry me. Femke ( talk) 19:43, 11 January 2022 (UTC)

Regarding the length I dont totally agree, since there are similarly big topics/articles (e.g. United States) where the lead is similarly long, but I am the last one to be against cuting it short (if content isnt lost). Nsae Comp ( talk) 20:21, 11 January 2022 (UTC)

Proposed new text

Earth is the third planet from the Sun and the only astronomical object known to harbour and support life. Its hydrosphere is the only one in the Solar System sustaining large bodies of liquid surface water. Furthermore Earth's surface is predominantly water, either as water ice at the polar regions, but mostly as liquid water making 71% of Earth's surface, domintated by a global Ocean, dwarfing other salt-water and freshwater bodies like lakes and rivers. The remaining 29% of Earth's surface is land consisting of continents and islands, most of it lying in the land hemisphere. The surface altogether rests on several rigid tectonic plates of Earth's lithosphere, which migrate over many millions of years, producing magmatic and seismic activity, and are driven by a convective mantle around a solid iron inner core and a liquid outer core, which generates Earth's magnetic field, deflecting destructive solar winds and shaping Earth's magnetosphere.

Earth has an atmosphere, consisting mostly of inert nitrogen, partially of reactive oxygen and in small amounts of other elements and water vapor, allowing widespread formation and systems of water clouds. Surface conditions are heavily regulated by the atmosphere; by its shielding, composition and circulation, along with the Oceanic circulation. The atmosphere, together with Earth's hydrosphere and lithosphere, is the environment that has been harbouring life on Earth, and has also been significantly shaped by life. Earth receives 1.361  kW/ m² solar irradiance, which reaches the surface unevenly and seasonally different at different latitudes. The distribution of Earth's energy budget through its environment results in a complex climate system, producing Earth's climate and phenomena rich weather. This system, with an anthropogenically increasing average surface temperature of 14 ° C, is sensitive to topographic differences and atmospheric changes, such as increases in atmospheric greenhouse gases, causing effects like global climate change.

Earth orbits around the Sun in about 365.25 days (a year) and at a distance of about eight light minutes (an astronomical unit, AU). Earth rotates at a period of 24 hours (a day), producing night- and daytimes, and its axis of rotation being tilted with respect to Earth's orbital plane, produces seasons on Earth. Earth has one permanent natural satellite, the Moon, which remained of a giant-impact with Earth during Earth's formation, having a size of a quarter of Earth's width, planetary-mass and being at an average distance of about 380,000 km (1.28 light seconds) from Earth. Earth is the densest planet in the Solar System and the most massive and largest of the four rocky planets, being an ellipsoid with a circumference of about 40,000 km. Earth's gravity (9.8 m/s² at its surface) interacts with other objects in space, tidally locking the Moon's rotation and its orbital operiod of about a month. While the Moon's gravity causes on Earth the main tides, stabilizes Earth's axial orientation and gradually slows its rotation.

Earth formed over 4.5 billion years ago and within the first billion years of Earth's history, the oceans and then life in it formed, first with anaerobic and then with aerobic organisms, leading to the Great Oxidation Event two billion years ago and the proliferation of life, particularly since the Cambrian explosion 550 million years ago. Occasionally punctuated by mass extinctions, life has adapted to Earth everywhere, and in its history on Earth has developed a broad biodiversity, with life today making a mere 1% of all species that have already lived on Earth. Home to humans, 8 billion people live on Earth, depending on it for survival. In Earth's current geological epoch, the Holocene, humans have been increasingly impacting Earth's environment, giving rise to the emerging Anthropocene. Today's human impact and exploitation is unsustainable and degrading for Earth's surface, orbits, hydrology, atmospheric processes, endangering other life and causing widespread extinction.

To be constructive, comparing the previous/current version with mine on HemingwayApp then there is not so much the difference in problematic sentances, but rather that I seem to have constructed the same amount of sentances but with more text. So that would mean for me to break down the content/sentances that I have provided in more sentances, choping the content into smaller easier digestable sentances. I really believe it is not fair to the readers to withhold a good overview because of a lack of effort put into puting it into better sentances. Something that I did today and was eager to do together. Nsae Comp ( talk) 20:35, 11 January 2022 (UTC)

We'll get there eventually, don't worry :). I will be slow, so hopefully there are some more prose or FA experts lurking here :). Femke ( talk) 20:45, 11 January 2022 (UTC)

Tony1 has made quite a few prose exercises that have helped me write somewhat close to FA level. WP:PLUSING may be useful for you. Femke ( talk) 20:55, 11 January 2022 (UTC)

Since I seem to be addicted to this lead, despite all the work being reverted, here my first proposal for the first para with less convaluted sentances (thanks to HemingwayApp). Choped up in a bit patronizingly small fingerfood sentances and keeping at the same time all of its content. Fascinatingly it even got shorter:

Proposals first paragraph

Earth is the third planet from the Sun. It is the only astronomical object known to harbour and support life. Its hydrosphere is the only one in the Solar System sustaining large bodies of liquid surface water. Water is predmoninant on Earth's surface. At the polar regions the surface is water ice. Liquid water makes up 71% of Earth's surface. A global Ocean takes up most of the area. The Ocean dwarfs all other salt-water and freshwater bodies like lakes and rivers. The remaining 29% of Earth's surface are continents and islands. Most of Earth's land is lying in the land hemisphere. The whole surface rests on several rigid tectonic plate. Tectonic plates migrate over many millions of years, producing magmatic and seismic activity. Cause for this activity is a convective mantle around a iron core. Earth's core generates a magnetic field. This field deflects destructive Solar winds and shapes Earth's magnetosphere.

Nsae Comp ( talk) 21:35, 11 January 2022 (UTC)

Even shorter and less patronizing:

Earth is the third planet from the Sun. It is the only astronomical object known to harbour and support life. Its hydrosphere is the only one in the Solar System sustaining large bodies of liquid surface water. Liquid water dominates with 71% Earth's surface. A global Ocean spans most of that area. This Ocean dwarfs all other salt-water and freshwater bodies like lakes and rivers. Water ice covers Earth's polar regions. The remaining 29% of Earth's surface are continents and islands. Most of Earth's land is lying in the land hemisphere. The whole surface rests on several rigid tectonic plates. Tectonic plates migrate over many millions of years, producing magmatic and seismic activity. Cause for this activity is a convective mantle around an iron core. Earth's core generates a magnetic field. This field deflects destructive Solar winds and shapes Earth's magnetosphere.

I could change also the rest of the paras into such a form, if it meets approval? Nsae Comp ( talk) 22:00, 11 January 2022 (UTC)

I think it would be easier for us to follow if you propose small changes to the lead. Because I had to keep flipping backwards and forwards to see the difference from the text above to current lead. For example you could start a new talk section to say why links to land hemisphere and magnetosphere should be in the first para. Or whatever it is you actually want to change in that para. I know this would be time consuming, but this is a featured article which presumably gets lots of views. Also probably easiest to agree what is to go in in principle before tweaking the English. I cannot see much wrong with the existing English apart from I propose changing "to harbour and support" to "to have evolved". Re content I think the existing last sentence of that para should be rewritten so that plate tectonics comes before tectonic plates. But, as it would take me a long time to figure out a good sentence for that, I am just going to make the tiny change in the first sentence - lets see if anyone reverts it. Chidgk1 ( talk) 15:04, 12 January 2022 (UTC)

Thanks for that Nsae Comp! In the climate change article, we usually do stripe out / underline when proposing new text, and explain each significant change. It works well, but is rather time-consuming. Not a request, just a suggestion. I've got some language, and some content comments.

• I don't know what problem we're solving. You indicate lack of logic, but I'm not sure how the old paragraph had a lack of logic.
• Liquid water dominates with 71% Earth's surface. -> not grammatical
• The key guideline we should look at is Wikipedia:Manual of Style/Lead section, which states: "Apart from basic facts, significant information should not appear in the lead if it is not covered in the remainder of the article.". A land hemisphere is not introduced in the body of the article, so cannot appear in the lead section. It is quite a niche framing, so I do not think it belongs in the article at all. I'm confident is does not belong in the lede.
  • There are more instances of this. In March, somebody introduced the word gulf into the lede, which we don't talk about in the body. Your proposal solves that issue. Maybe a broader recheck is necessary.
• What is water ice? Even scientific literature typically does not put the word water in front of ice, unless maybe in astonomy? Ice suffices.
• Ocean -> ocean
• The text doesn't flow (I think you recognise the same in the word "patronising"). You've sought to make the text more readable by mostly reducing sentence length, rather than sentence ánd word length, which would lead to more natural-sounding language. When we agree on content, we can always ask for help at WP:GOCE. I'm struggling with the same issue often. Femke ( talk) 17:01, 12 January 2022 (UTC)

To reply to some points of you:

• e.g. regarding logic: the first para mentions the land percentage before the water percentage, this was one of the first things that I switched because Earth's water surface is the more important and special thing about Earth. The latter is something that I tried to flash out by adding "Its hydrosphere is the only one in the Solar System sustaining large bodies of liquid surface water.", I find that very important ... I tried to continue the logic of the first sentance of highlighting the specialness of Earth and tried to move all related topics about Earth's water & surface together. Surface was then the thread that bridged to tectonics etc. ... such textual threads are what I tried to build and group and what I meant with logic. PS: magnetosphere is an important element of Earth to grasp Earth in its entirety and it fits at that spot thematically.
• Liquid water: well its my poor talent trying to word it correctly, because the common phrase of "water covers the surface" is wrong in planrtary cases, liquid water IS in this case the surface. If you manage to write it correctly without sounding off, then you get my personal nobel literature price.
• Water ice: well astronomy is exactly why I wrote it like that, Earth is an astronomical object first and formost. But whatever, ice will do too, even if it is confusing when in astronomy people dont add what kind of ice, but thats maybe more an issue of other astronomical articles where it is not clear that it is water ice.
• Ocean is correct since I wrote about the Ocean. For Earth the Ocean is the dominant surface characteristic afterall and not to be understood in its arbitrary oceans-sections at the lead level. I find this important when talking about Earth from a global perspective, as this article inherently should be, especially when considering climate change and environmental impact.
• You can rewrite the sentances as much as you want, I am all about the content and issues raised, language is not my focus or thing.

Nsae Comp (
talk) 20:10, 12 January 2022 (UTC)

• I don't mind which percentage comes first, so I've changed it to be water first.
  • Which statement(s) in the body do you rely on to say "Its hydrosphere is the only one in the Solar System sustaining large bodies of liquid surface water."? Not sure about the grammar here, it feels slightly off. (not a native speaker).
  • The word seismic is jargon. Is earthquake a synonym?
• The word cover in English has two meanings: extend over (the meaning here), and to be on top of (which would be incorrect). I've put the word in a different place, where there is no ambiguity remaining.
• I'd say: earth is foremost the place that readers live. Natural-sounding text (not too academic) is usually best.
• I've looked up some style guides, and I don't see ocean capitalised. I've removed the word global, as it's unnecessary if one changes the article (a global ocean vs the ocean).

P.S. It's sentence. Femke ( talk) 20:37, 12 January 2022 (UTC)

Regarding o/Ocean well I seem to be coming too much from astronomy, since ocean can mean any ocean, and the Ocean, well, the Ocean. But fair enough if it is not established enough. At Moon we had similar problems: capitalized Moon for the Moon is accepted today, but funnily enough "Lunar" not (we agreed it will be resolved in 2092, when we have been to more moons and spent more lunar quality time ... same here I guess when we have been to more extraterrestrial (subsurface) oceans. The usual problem: wikipedia can only work with what is established enough. As I said: fair enough.

PS: regarding land hemisphere; well I must admit it is also still a seldom used concept, but I found it very useful to underline the non-dominant nature of Earth's land-surface. So similar issue as above I guess. Nsae Comp ( talk) 21:09, 12 January 2022 (UTC)

• regarding water as significant difference to other Solar Sys objects the text-body states:"The abundance of water on Earth's surface is a unique feature that distinguishes it from other planets in the Solar System." Nsae Comp ( talk) 21:18, 12 January 2022 (UTC)
• PS: regarding land hemisphere; the article does indeed mention it, it just doesnt label it exactly the same:"The Northern Hemisphere contains 68% of the world's land mass." ... but this might very well link to the article about water/land hemisphere. I wouldnt mind navigating around the term "land hemisphere", but I very much vote for pointing out in the lead that water and land have significantly higher concentrations on opposing sides of the planet. I would be ok to write something like:"For example the Ocean spreads with the Pacific also allmost exclusively over one half of Earth's surface area. The Souther hemisphere is congruent with that area, so is the Northern hemisphere with most of Earth's land". ... or in any other wording constellation. Nsae Comp ( talk) 21:39, 12 January 2022 (UTC)

@ Femkemilene: thank you for your edits regarding the ocean and water cover, but I want to argue for trying to keep the word hydrosphere (even more so as with magnetosphere) because I find it indeed patronizing to withhold such a concept out of the reason of not being known enough, since Wikipedia has afterall the mission to inform and give orientation and not just pack everything in a giant body of text where everyone gets lost in neatly cited mass of details without a guidingly introducing overview. Nsae Comp ( talk) 22:15, 12 January 2022 (UTC)

I must say the first para looks good to me now; I can painfully agree on quite some things being cut that I proposed (e.g. linking to planetaty surface, magmetic activity, or even magnetosphere), but what I really find necessary is to include the sentance about why Earths hydrosphere is special (in the Solar System) + I really would like to see the reference about the solar wind in it, because it is a very important factor in planetary issues (e.g. its the reason why other inner planets have no liquid surface water). So if those two things find their way then for my part is the first para ticked as done. Nsae Comp ( talk) 12:52, 13 January 2022 (UTC)

The reason I did not use the word hydrosphere is it's already used in the second paragraph, so would be repetitive. I think the sentence is ungrammatical Its hydrosphere is the only one in the Solar System sustaining large bodies of liquid surface water, so I'm hesitant to add it. Pinging @ Clayoquot, as her prose quality is better than mine.

As for the text about the magnetosphere, I'm not sure how that all works, but maybe @ Mikenorton can comment. I'm also not quite sure what "Earth's core remains active, generating Earth's magnetic field." means. I thought the word active means something like "liquid and convectively active", which isn't true for the entirety of the core. But maybe the word active means something different.. Femke ( talk) 17:16, 13 January 2022 (UTC)

Regarding the core, you're right that it's only convection in the liquid outer part that generates the magnetic field - the inner core just provides the heat source for the convection. As to the magnetosphere, we could turn that text around "This shapes Earth's magnetosphere that deflects destructive Solar winds." So perhaps in combination "Earth's liquid outer core generates the magnetic field that shapes Earth's magnetosphere, deflecting destructive Solar winds." Mikenorton ( talk) 18:49, 13 January 2022 (UTC)

I must say that beside the water-specialness and solar wind I forgot to say that the reference about land and water surface areas dominating opposite hemisphere is also quite good for particularly an overview like the lead (once again underlining the water-world character of Earth). Nsae Comp ( talk) 21:02, 13 January 2022 (UTC)

I think it's WP:undue. Do you have references that give so much prominence to that idea? Femke ( talk) 21:08, 13 January 2022 (UTC)

Well I cant say I do, even if it is self evident for everyone that has a globus or can use Google Earth. I guess I have to be satisfied that the lead states that most of the planet's surface is water/ocean and leave it up to the reader to think about how the water (or land) takes up the area. For me it was logical to describe a surface by coverage as well as distribution. PS: I dont think it needs to be prominent to be due, if it describes/illustrates a very much due issue namely how Earth's surface looks like, which is a perfect way to introduce a terrestrial planet. Nsae Comp ( talk) 00:50, 14 January 2022 (UTC)

I think "hydrosphere" is overly technical for the lead. How about "While water and ice are found on other planets and moons in the Solar System, only Earth sustains large bodies of liquid surface water"? Clayoquot ( talk | contribs) 21:23, 13 January 2022 (UTC)

Thx. Fine with me. Nsae Comp ( talk) 21:38, 13 January 2022 (UTC)

• Sorry for the unrelated reply above, but to not loose the suggestion of @ Mikenorton: and to finish some sentences: how about taking Mikenorton's sentence? > "Earth's liquid outer core generates the magnetic field that shapes Earth's magnetosphere, deflecting destructive Solar winds." Nsae Comp ( talk) 19:16, 15 January 2022 (UTC)

 Done Nsae Comp ( talk) 19:34, 15 January 2022 (UTC)

• I have an issue with the sentence about plate tectonics - all versions state that plate movement is driven by a convecting mantle. The driving force for plate tectonics is certainly a matter of debate, see this recent paper for a review of the potential drivers, but most geoscientists think that it is some sort of "top-down" process, driven mainly by subduction, the so-called "slab pull" force, with "mantle drag" being a secondary force, although of local importance. That said, I'm struggling to come up with some words to convey this simply. Mikenorton ( talk) 08:49, 14 January 2022 (UTC)

I also note that the body of the article doesn't describe the driving force at all. Mikenorton ( talk) 08:56, 14 January 2022 (UTC)

I dont have a problem with just saying "Earth's surface rests on several slowly moving rigid tectonic plates." ... possibly with an addition that Earth is volcanic and seismic active ;) Nsae Comp ( talk) 16:23, 14 January 2022 (UTC)

How about this more complete sentance in my opinion (and rigid is gone):"Earth's surface rests on several slowly moving tectonic plates, producing belts of mountains, volcanos and earthquakes." Nsae Comp ( talk) 07:06, 15 January 2022 (UTC)

Following that suggestion, how about "Earth's surface layer is formed of several slowly moving tectonic plates, interacting to produce mountains, volcanoes and earthquakes."? Mikenorton ( talk) 10:24, 15 January 2022 (UTC)

Looks fine to me. Thinkinh; or is instead of mountains "topography" better because otherwise we get people to add all kind of topographic elements like rifts, etc.? Nsae Comp ( talk) 12:32, 15 January 2022 (UTC)

I don't personally think that will be an issue and even completely flat topography is still topography. Could have "mountain ranges" rather than just "mountains". Mikenorton ( talk) 12:38, 15 January 2022 (UTC)

Then I would use the space of an extra word to find a word that summurizes valleys, rifts, etc. So for example:"Earth's surface layer is formed of several slowly moving tectonic plates, interacting to produce valleys, mountains, volcanoes and earthquakes." Nsae Comp ( talk) 13:05, 15 January 2022 (UTC)

Or "faults" instead of valleys. Nsae Comp ( talk) 13:16, 15 January 2022 (UTC)

Neither faults nor valleys I think, perhaps "basins" so - "Earth's surface layer is formed of several slowly moving tectonic plates, interacting to produce mountain ranges, basins, volcanoes and earthquakes." Mikenorton ( talk) 16:42, 15 January 2022 (UTC)

I like the one with only mountain(s) (ranges), volcanoes and earthquakes. Basins is minor jargon imo, and not necessary. Femke ( talk) 18:00, 15 January 2022 (UTC)

I also prefer the suggestion ""Earth's surface layer is formed of several slowly moving tectonic plates, interacting to produce mountain ranges, volcanoes and earthquakes." I would go for "mountain ranges" rather then just "mountains", because a large proportion of mountains are also volcanoes. I know that leaving out topographic lows like oceanic trenches is missing out some of the overall picture, but those three things that result from plate tectonics are the ones that our readers are likely to be familiar with - "basins" less so - we don't even have a decent article to link it to, as I don't think that depression (geology) really does the job. Mikenorton ( talk) 19:20, 15 January 2022 (UTC)

I tell my self that "mountain ranges" imply valleys (and in an associative way also trenches) etc., so I would say I am ready to put it into the lead as suggested ("Earth's surface layer is formed of several slowly moving tectonic plates, interacting to produce mountain ranges, volcanoes and earthquakes."). Nsae Comp ( talk) 19:26, 15 January 2022 (UTC)

 Done I took the liberty to add the sentence because everyone who commented was fine with it now. Only sentence missing if you ask me is the one about Earth being the only place with liquid surface water; see above! Nsae Comp ( talk) 19:52, 15 January 2022 (UTC)

• I dont want to fuzz and start a big discussion, but I find the sentence about the polar regions a bit without connection. So firstly I would put it inbetween the water and land surface sentences. It fits imho also because ice is something inbetween those two. But on the other hand it doesnt fit into either percentage of water/land. Secondly I would write to put it more in relation with the water sentence the following way:"Water in the form of ice covers most of Earth's polar regions." or "At Earth's polar regions the surface consists mostly of ice"? ... but somehow mentioning the poles isnt worth it alltogether. For Mars e.g. it would because it is the only place with water, but for Earth's water it is trivial. So if the poles are mentioned it should be about them as a climate zone (more so than about its position in the magnetic field). So leave as it is, move, rewrite, take out, refocus; I am for all of it, just wanted to raise the issue; though tending to taking it out considering the doctrine to shorten the lead (then there is also more space for the note of Earth's water in the Solar System ;p) Nsae Comp ( talk) 20:35, 15 January 2022 (UTC)

I have to go even further since I just realized that the 71% do not include lakes, raising like with the issue of polar ice the question how water coverage is dealt with in describing Earth's surface. We might as well write, that "Water is allmost omnipresent on Earth's surface, with about 72% of it being made up of liquid water. The ocean covers virtually all of that area, leaving 1% to lakes and rivers." ... or even ... "While large amounts of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 72% of the Earth's surface is made up of water. The ocean covers virtually all of that area, leaving 1% ^[1] to lakes and rivers." PS: land area would need to be updated to 28% as well of course. Nsae Comp ( talk) 22:45, 15 January 2022 (UTC)

Well I can hear you allready say that it is not mentioned in the body (other than mentioned unclear in a reference footnote, see my recent clarification edit). Besides there is also the 75% ^[2] number of water (incl. ice) cover of Earth. So it indeed might be less confusing for the lead to use the widely used 71%. But even if so the text has to make it clearer that the 71% is the ocean cover. So my (hopefully) final proposal:"While large amounts of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes and rivers." (also integrating the sentence about polar ice) Nsae Comp ( talk) 00:14, 16 January 2022 (UTC)

I take it that we have moved on to the other paras, that I can move this into the lead and close thise para? Nsae Comp ( talk) 02:16, 18 January 2022 (UTC)

 Done Nsae Comp ( talk) 19:48, 19 January 2022 (UTC)

OK, but we now have more about water in the solar system than is found in the "Hydrosphere" section in the body, which also doesn't talk about "liquid water". I think that we need to row back a little on that. Perhaps instead of " While large amounts of water can be found throughout the Solar System, only Earth sustains liquid surface water.", we can base it on the text from the body "The abundance of water on Earth's surface is a unique feature that distinguishes it from other planets in the Solar System." as "Other bodies in the solar system have water, but Earth uniquely has liquid water on its surface" or something similar, although we would still need to add something to the "Hydrosphere" section to mention "liquid water" if we want it to appear in the lede. Mikenorton ( talk) 20:34, 19 January 2022 (UTC)

With pleasure have I added that in the body. Nsae Comp ( talk) 21:22, 19 January 2022 (UTC)

Second paragraph

Current:

Earth's atmosphere consists mostly of nitrogen and oxygen. More solar energy is received by tropical regions than polar regions and is redistributed by atmospheric and ocean circulation. Greenhouse gases also play an important role in regulating the surface temperature. A region's climate is not only determined by latitude, but also by elevation and proximity to moderating oceans, among other factors. Severe weather, such as tropical cyclones, thunderstorms, and heatwaves, occurs in most areas and greatly impacts life.

Proposal:

Earth has an atmosphere, consisting mostly of inert nitrogen, partially of reactive oxygen and in small amounts of other elements and water vapor, allowing widespread formation and systems of water clouds. Surface conditions are heavily regulated by the atmosphere; by its shielding, composition and circulation, along with the Oceanic circulation. The atmosphere, together with Earth's hydrosphere and lithosphere, is the environment that has been harbouring life on Earth, and has also been significantly shaped by life. Earth receives 1.361  kW/ m² solar irradiance, which reaches the surface unevenly and seasonally different at different latitudes. The distribution of Earth's energy budget through its environment results in a complex climate system, producing Earth's climate and phenomena rich weather. This system, with an anthropogenically increasing average surface temperature of 14 ° C, is sensitive to topographic differences and atmospheric changes, such as increases in atmospheric greenhouse gases, causing effects like global climate change.

Nsae Comp ( talk) 22:01, 12 January 2022 (UTC)

To furthermore explain the logic that apllied to the other paras: Regarding the atmosphere I took the previous composition sentance and changed it to give an idea how the proportions and main characteristic are. Then I continued on mentioning one of the most important constants, leading the reader to energy budget issues and therefore climate and its complexity and change with its important reference value of globale average temperature. Nsae Comp ( talk) 20:23, 12 January 2022 (UTC)

This seems to be the same paragraph as before.. It still does not comply with the WP:LEAD guideline, containing many statement and connections that are not found in the body of the text. As such, it does not meet the verifiability policy.

The sentence with the words "Earth energy budget" is incorrect. The budget is simply the top-of-atmosphere balance between incoming and outgoing radiation. It's not the energy flows within the climate system.

As the paragraph is far from meeting the LEAD guideline, I'm not commenting on grammar and prose yet. Femke ( talk) 17:00, 13 January 2022 (UTC)

More on content: I do not think that the word shielding is clear here. If it refers to the magnetic field, that would already be covered by the sentence on solar winds in the previous paragraph (more clearly). Femke ( talk) 19:24, 13 January 2022 (UTC)

Yes its just a copy of the proposed and current paras to put them in comparison.

That about the energy budget can go if it doesnt work, the general idea, that the atmosphere is important for regulating Earths environment.

No, and I must admit I cut it too short here, "shilding" I meant the shielding that the atmosphere does: UV/ozone, meteorites, etc., it can deffinately use a better text/use.

Fascinating!! You are right I cant find solar irradiance in the body! Such a fundamental factor not mentioned... much to do here it seems. ...shocking... Nsae Comp ( talk) 20:34, 13 January 2022 (UTC)

Excited to see a new proposal with my feedback either incorporated or explained why not

I'm all up for adding solar irradiance to the body, but I'm firm in my belief it does not belong in the lead. It has a unit that people do not encounter everyday (especially now that light bulbs are measured in lumen rather than Watt), and it's a number people do not have a reference frame for. Even as a climate scientists who has read about climate science on other planets, I don't really have a good idea how this number varies. Femke ( talk) 20:47, 13 January 2022 (UTC)

Well the addition to the body is done. But I cant follow you that kW are a foreign concept, dont you have energy bills? What do your bulbs say what energy they use? And hopefully people get into photovoltaic power and the energy of electric cars are meassured in kW. Etc. Saying kW is not known is quite outdated at least. Nsae Comp ( talk) 21:14, 13 January 2022 (UTC)

Yeah, you're probably right that there are more locations non-scientists would encounter kW. Still, the translation of everyday power into what it means on a planetary scale is non-trivial. Open to more opinions here :). Femke ( talk) 18:36, 15 January 2022 (UTC)

So here my shorter update, taking the above arguments in and leaving out quite a bit... though I dont know if it is well enough structured and therefore might lack crucial cornerstones/issues:

Earth's surface is covered by its atmosphere, which consists mostly of nitrogen, partly of oxygen and in smaller amounts of other components. It has been hosting surface conditions for the widespread presence of water vapor and its extensive formation of clouds, as well as for the spread of life. Earth's climate is strongly driven by the energy from the Sun reaching Earth, producing seasons which differ across the latitudes. Earth's climate is sensitive to topographic differences and atmospheric changes, such as increases in atmospheric greenhouse gases, causing effects like global climate change. Life has been shaping Earth's atmosphere over long periods of time, with humans currently changing it rapidly. Humans have lowered in the past its protective function towards space through ozone depletion and are causing a demanding increase in surface temperature from 14 ° C.

Nsae Comp ( talk) 02:35, 22 January 2022 (UTC)

Not quite there yet. Sorry for slow response. Taken up more than I can do with my limited energy.

• You already describe (correctly there) what is causing seasons in the third paragraph.
• I do not understand the sentence starting with 'has been hosting'. What does its refer to?
• Why mention climate change both here and in the last paragraph. It fits better there, as climate change is one of humanity's impacts
• Why topographic differences rather than elevation. Seems like an unnecessary complication
• Try to avoid the present perfect continuous tense. It's very rare in this context (native speakers may be able to explain better)

This paragraph is far from ready for mainspace imo. Ask yourself what section of the body you are summarising. It used to be a summary of section 7, but now you're mixing in some of 9 too. But you're summarising 9 in the fourth paragraph too. And ozone depletion is not in the article (it probably should be, but needs to be added to the body first). Femke ( talk) 17:50, 25 January 2022 (UTC)

Dealt with the ozone hole (lol sry that had to be). I agree that there is some overlap but it is a crucial issue. Though I tried to minimize it now. I reworded. Last but not least I also took the ozone depletion from the lead, maindespite being in pain about that (I took it out because then you could mention many other things too, so I stuck with climate change as the main issue).

Earth's surface is covered by its atmosphere, which consists mostly of nitrogen, partly of oxygen and in smaller amounts of other components. Water vapor is widely present and is extensively forming clouds. Greenhouse gases like water vapor and carbon dioxide (CO₂) retain a part of the energy reaching Earth from the Sun, generating a complex climate and an average surface temperature of 14 ° C. Life has significantly shaped the atmosphere over long periods of time. More rapidly humans have been changing Earth's greenhouse gases, causing an increasing average surface temperature and the demanding climate change. Surface conditions are sensitive to atmospheric changes and can be impacted with relatively small changes.

Nsae Comp ( talk) 00:47, 27 January 2022 (UTC)

Here an even shorter/more concise version:

Earth's surface is covered by its atmosphere, which consists mostly of nitrogen, partly of oxygen and in smaller amounts of other components. Water vapor is widely present and is extensively forming clouds. Greenhouse gases like water vapor and carbon dioxide (CO₂) retain a part of the energy reaching Earth from the Sun, generating a complex climate and an average surface temperature of 14 ° C. Life is significantly maintaining beneficial levels of atmospheric components, like greenhouse gases. Humans have been changing this, causing among other things an increasing average surface temperature and the demanding climate change.

Nsae Comp ( talk) 02:42, 27 January 2022 (UTC)

@ Mikenorton, Femkemilene, and Clayoquot: I know we have been excited to close the last para allready, but this one is still open. Can we finish this thread and find out if the above text is okay to be inserted? As I said I find it not redundant to have here also life and humans and their impact mentioned, since it is such a central issue. The only reason for me to maybe not have it, is to emphazies that climate impact and change is not the only critical environmental issue. But is it really that equal to other issues? Nsae Comp ( talk) 21:42, 27 January 2022 (UTC)

Still don't think it's an improvement. Apart from the redundancy, I see another problem. It's not only greenhouse gases (or energy in a different reading of the same sentence) that generates climate. It's a lot of things together. I don't understand "Life is significantly maintaining beneficial levels of atmospheric components". Nor "demanding climate change".

That said, I do think the current paragraph needs some copyediting from a native speaker. Femke ( talk) 21:10, 28 January 2022 (UTC)

Well since I am running out of breath here, lets talk about it the other way around, looking what the current para is missing, on a statemnt by statement level. The statements that I am missing and see crucial also in that order are:

1) " Water vapor is widely present and is extensively forming clouds."

2) " Greenhouse gases like water vapor and carbon dioxide (CO₂) retain a part of the energy reaching Earth from the Sun."

3) "Earth has an average surface temperature of 14 ° C."

As I said I find also thw part about life and humans important, but since it is in the last para touched on, I can live it that no one cares about it as much as I do.

The last thing is the first sentence, which could be more nuanced and naturally I like my version better than the current. So it would be great to have that nuancing also:"Earth's surface is covered by its atmosphere, which consists mostly of nitrogen, partly of oxygen and in smaller amounts of other components."

So thats it for me if these three statements and maybe the first sentence can get in, then Ill leave this para and lead be and thank you all for the work. Nsae Comp ( talk) 16:04, 29 January 2022 (UTC)

Running out of breath.. Don't tell me about it. Bloody long covid

1. Too tired to think of better prose here. The word extensively feels wrong. No text in the body (again) to fall back on. Water forming clouds doesn't need a cite, but the more subjective extensive may do.

2.  Done

3. To make this sentence accurate (Earth had an average surface temperature of 14 °C (MOS says no linking)), you'd have to add between 1950 and 1980, which is too much numerical information to make good prose. This fits better in the infobox, where it is already given. Femke ( talk) 19:16, 29 January 2022 (UTC)

ad 2) thank you (even if water vapor made sense for me to make clear that CO2 isnt the only one, but its ok) ad 3) well ok, since that sentance works best if comined with humanity's impact, and with that gone it is indeed lost. ad 1) since this is important to describe Earth imho, I have added now a references in the text. The reference speaks of clouds "dominating" the view of Earth (67%). So, somewhat longer, but less unclear, I suggest:" Water vapor is widely present and is forming clouds which cover most of the planet." Nsae Comp ( talk) 06:21, 30 January 2022 (UTC)

I like that sentence. I've added it, and made space by copy-editing another sentence. Thank you a lot for your work :). I hope my insistence that we stick to guidelines meticulously wasn't too frustrating.

Grammar note: simple facts are described with the simple present tense, rather than the continuous tense: 'forms clouds' rather than 'is forming clouds' Femke ( talk) 09:07, 30 January 2022 (UTC)

Thank you very much and thank you as well for sticking around and constructively work on this. I hope you will soon recover from your long-covid! Nsae Comp ( talk) 06:06, 31 January 2022 (UTC)

Third paragraph

Current:

Earth's gravity interacts with other objects in space, especially the Moon, which is Earth's only permanent natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.

Proposal:

Earth orbits around the Sun in about 365.25 days (a year) and at a distance of about eight light minutes (an astronomical unit, AU). Earth rotates at a period of 24 hours (a day), producing night- and daytimes, and its axis of rotation being tilted with respect to Earth's orbital plane, produces seasons on Earth. Earth has one permanent natural satellite, the Moon, which remained of a giant-impact with Earth during Earth's formation, having a size of a quarter of Earth's width, planetary-mass and being at an average distance of about 380,000 km (1.28 light seconds) from Earth. Earth is the densest planet in the Solar System and the most massive and largest of the four rocky planets, being an ellipsoid with a circumference of about 40,000 km. Earth's gravity (9.8 m/s² at its surface) interacts with other objects in space, tidally locking the Moon's rotation and its orbital operiod of about a month. While the Moon's gravity causes on Earth the main tides, stabilizes Earth's axial orientation and gradually slows its rotation.

Nsae Comp ( talk) 22:03, 12 January 2022 (UTC)

The third para I rearranged to move orbital elements first and then continue with sizes and gravitational influence etc.. I must admit that this para is a bit numbers heavy, but do find it important to give an introduction to some cornerstone-numbers when a reader wants to get into Earth as a topic and to find their bearings in its planetary cosmos. Nsae Comp ( talk) 20:40, 12 January 2022 (UTC)

• This repeats a lot of information from the infobox. As numbers in prose are always tricky in terms of prose quality, I would be against adding this duplicate information.
• The proposal contradicts the body, implying certainty about the giant impact hypothesis. Not my expertise, so don't know what is true.
• I think adding the eight light minutes distance is an improvement (I previously objected to adding the unit here, which would be more suitable for a text-book like article)
• Don't mind the shufling of information
• Prose tinkering needed after we agree on content. Femke ( talk) 17:03, 14 January 2022 (UTC)

• Shufling done.
• I understood now that "eight light minutes" is ok, but AU too much; which would be fine with me (possibly though being linked to AU).
• Surface gravity I gree can be read from the infobox, especially since it is only in comparison with other planets, thus on their pages of worth mentioning in the lead. What I would keep is the distance numbers of the Sun, Moon and Earth's circumference, because they discribe important properties and give a sense of scale that Earth is and is in 40000km circumference => 380000km (1.2ls) => 8 light minutes, producing a nice transition from terrestrial scales to interplanetary scales by transitioning terrestrial km distance to lightseconds. Nsae Comp ( talk) 20:19, 14 January 2022 (UTC)

  That makes sense. If you propose another version of the paragraph, one of us will tackle the prose quality. I wouldnt like to AU, as it may be a bit of an unexpected link ( Wikipedia:EGG). Femke ( talk) 19:04, 15 January 2022 (UTC)

Ok, so I have left out the values of Earth's gforce and astronomical unit and rearranged for logic reasons my proposed text quite a bit:

" Earth is an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets it is the largest and most massive. Earth is about eight light minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Earth also rotates and completes a rotation in a day (24 hours). With respect to Earth's orbit around the Sun, the axis of Earth's rotation is tilted, producing seasons, as well as Earth's day- and nighttime. Earth is orbited by one permanent natural satellite, the Moon. The Moon's rotation and orbit is synchronized, with a period of about a month, through tidal locking with Earth, forcing the Moon's near side to allways face Earth. The Moon is roughly a quarter as wide as Earth and causes on Earth with its planetary sized mass and orbit the main tides, stabilizes Earth's axial orientation and gradually slows its rotation."

Nsae Comp ( talk) 01:05, 17 January 2022 (UTC)

Edited proposal vs original:

Earth's gravity interacts with other objects in space, especially the Moon, which is Earth's only permanent natural satellite. Earth orbits around the Sun in about 365.25 days. Earth's axis of rotation is tilted with respect to its orbital plane, producing seasons on Earth. The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth's orientation on its axis, and gradually slows its rotation. Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.

Earth is an ellipsoid with a circumference of about 40,000 km. It is the densest planet in the Solar System. Of the four rocky planets, it is the largest and most massive. Earth is about eight light minutes away from the Sun and orbits it, taking a year (about 365.25 days) to complete one revolution. Earth rotates around its own axis in a day. Earth's axis of rotation is tilted with respect to its orbital plane with the Sun, producing seasons. Earth is orbited by one permanent natural satellite, the Moon, which is roughly a quarter as wide as Earth. The Moon always faces the Earth with the same side through tidal locking and causes tides, stabilizes Earth's axis and gradually slows its rotation.

What do you think of the above? I've not checked it against the body. I'm sure other people can improve the prose further.

• I've dealt with WP:OVERLINKING
• tried to reduce sentence complexity
• Removed that the axis tilt of orbital plane causes day/night (it's of course Earth's rotation around itself). Femke ( talk) 17:13, 17 January 2022 (UTC)

I like it. My links to year and day were because they are such crucial but also complex concepts, but its ok since rotation and orbit are linked (similarly with day/night). But I realized just now that I forgot yesterday to add the part about the Moon's distance to complete the little distance/size overview with the distance to the Sun and size of Earth & Moon given allready in the para. So here my little insert:"Earth is orbited by one permanent natural satellite, the Moon, which orbits Earth at 380.000 km (1.3 light seconds) and is roughly a quarter as wide as Earth."? Nsae Comp ( talk) 20:31, 17 January 2022 (UTC)

Okay. That sentence has easy content, so it's okay if it's a bit longish. Ready for mainspace imo, where others can further improve wording. Femke ( talk) 20:44, 17 January 2022 (UTC)

Fourth paragraph

Current:

According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the ocean and began to affect Earth's atmosphere and surface, leading to the proliferation of anaerobic and, later, aerobic organisms. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions. More than 99% of all species that ever lived on Earth are extinct. Almost 8 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans increasingly impact Earth's surface, hydrology, atmospheric processes, and other life.

Proposal:

Earth formed over 4.5 billion years ago and within the first billion years of Earth's history, the ocean and then life in it formed, first with anaerobic and then with aerobic organisms, leading to the Great Oxidation Event two billion years ago and the proliferation of life, particularly since the Cambrian explosion 550 million years ago. Occasionally punctuated by mass extinctions, life has adapted to Earth everywhere, and in its history on Earth has developed a broad biodiversity, with life today making a mere 1% of all species that have already lived on Earth. Home to humans, 8 billion people live on Earth, depending on it for survival. In Earth's current geological epoch, the Holocene, humans have been increasingly impacting Earth's environment, giving rise to the emerging Anthropocene. Today's human impact and exploitation is unsustainable and degrading for Earth's surface, orbits, hydrology, atmospheric processes, endangering other life and causing widespread extinction.

Last but not least the fourth para: well I tried here to structure it chronologically and focus on what life and humans mean when speaking about Earth as a geological issue. Here I disarmed some sentences about extinction, since they sounded like previous editory having thrown arguments at each other about climate change (e.g. 99% all life allready extinct; I tried to focus that statement on its message of life being old and diverse. From fractions and spread of diversity I continued to humans as one tiny frction of Earth's life's diversity but also their impact on Earth and its life. Trying to make humans and their impact less sound detached from Earth as a topic and less about the humans (e.g. focusing on "degrading Earth" instead of impact of humans being about their survival; in the context of the article Earth at least. Nsae Comp ( talk) 20:59, 12 January 2022 (UTC)

I'm not convinced by most of these proposed changes. Maybe best to continue from the old version and make some minor tweaks

• I like the explanation of how we know when Earth was formed
• I think the sentence about earlier life can indeed be omitted (even though it's really cool)
• I think the 99% was better, I don't see the connection with climate change. Mere is a subjective term, which should rarely be used on Wikipedia.
• The Anthropocene is still not formally accepted as an epoch, I don't think you can say it like this. (and it's not in the body)
• I think the statements about humans can be a bit stronger, but feel the wording may be too strong to completely comply with Wikipedia:Neutral point of view. I think the orbits is too small an issue for the lede, and probably unclear for the average reader.

Femke ( talk) 20:54, 17 January 2022 (UTC)

Working from the current text I have implemented your comments and inserted the things that I see mostly missing. First the emergence of the ocean needs to be mentioned. Secondly I agree and argue even further that most of the sentences about life can be skiped. But since I dont care about para length only about structure and giving a good overview for orientation, so I dont care if they stay. For me it was important to give a chronological Earth and not life focused narrative, therefore I used that now to introduce humans to the text. Bigest problem I have are the 99%, this is a redundant argument that is imho only used by climate change deniars, and it does not give a good feeling of evolution's scale, it merely says how short human life is. Last but not least I took parts of my last sentences, because they are in my opinion stronger than the current and as little subjective as possible. For me terms like impact, exploit, (un-) sustainable, degrading, people's lifes, endangering and extiction have to be there to describe properly the dimensions of the issue. Particularly the reference to impact on human and other life was too small imho. E.g. I refrained from inserting links to climate change under "climate" and "ecosystems", but the three about life need to point towards their articles (though maybe there is a better article to link to for "people"). I did also reword instead of surface and hydrology I wrote soils and waters to a simpler language and sticking with main enviornments (omiting in pain the orbit).

Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, the ocean and then life in it formed. Life spread globally and began to affect Earth's atmosphere and surface, leading to Earth's Great Oxidation Event two billion years ago. Some geological evidence indicates that life may have arisen as early as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive. In the history of life on Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinctions. More than 99% of all species that ever lived on Earth have disappeared. Humans emerged 300.000 years ago on Earth, having today a population of 8 billion. Humans depend on Earth's biosphere and natural resources for their survival, Humans have increasingly impacted Earth's environment. Today humans exploit unsustainable and degrading Earth's climate, soils, waters and ecosystems, threatening people's lifes, endangering other life and causing widespread extinction.

Nsae Comp ( talk) 04:34, 18 January 2022 (UTC)

The term I have the most difficulty with is degrading, which is typically used for human's impacts on soil (as a noun rather than a verb), but not climate or ecosystems. Via Google I find two definitions of degrade:

• "treat or regard (someone) with contempt or disrespect"
• "break down or deteriorate chemically"

I think exploit is fine. But, we're not exploiting the climate, we're exploiting fossil fuel that impact the climate, so the language is off. Endangering other life and causing widespread extinction feels redundant to me. Maybe just go with the second?

I hope there will me more input from other editors here. Maybe somebody else wants to have a shot at proposing a compromise

P.S. you should care about paragraph length if you want people to read your overview and structure. Easy text has between 50-100 words. I've found between 100-150 words per paragraph a good compromise for Wikipedia articles. Your 268 word explanation above was difficult to parse for me. Femke ( talk) 19:02, 20 January 2022 (UTC)

Thanks and yes please more input by others!

I crinch taking endangering out, but true it is a bit redundant with the extinction part. Furthermore I dont need to stick with "degrading" and you made me realize the combination of exploit and unsustainable is odd, since exploitation is kind of per definition never really sustainable in a finite world if it it refers mainly to natural resources, maybe exploitation is therefore more about it possibly being escalating or depleting, or something like that. I thought of writing "Driven by exploitation today humanity's impact on Earth's climate, soils, waters and ecosystem has become unsustainable," but that didnt sound neutral anymore and is a bit too much of a detail for the lead of Earth; except if you deem that this is warrented, then I am glad if it finds its way in. But here my updated version (without exploitation and the other discussed issues):

Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, the ocean and then life in it formed. Life spread globally and began to affect Earth's atmosphere and surface, leading to Earth's Great Oxidation Event two billion years ago. Humans emerged 300.000 years ago on Earth, having today a population of 8 billion. Humans depend on Earth's biosphere and natural resources for their survival, Humans have increasingly impacted Earth's environment. Today humanity's impact on Earth's climate, soils, waters and ecosystem has become unsustainable, threatening people's lifes and causing widespread extinction of other life.

ad P.S.: sorry for being inprecise; well I didnt mean its unimportant, but for me finding shorter sentences after adding content is the way to go, instead of not adding something because I havent come up with a shorter text. Nsae Comp ( talk) 22:38, 21 January 2022 (UTC)

This thread has been up now for two weeks and I have been on this for three, no more people are joining in and the ones who did are also less active. So I would suggest to put the last proposal of para two and four in and let the direct editing have a go from here? Then we coukd close this. Nsae Comp ( talk) 20:28, 24 January 2022 (UTC)

• Humans emerged 300.000 years ago on Earth, having today a population of 8 billion. It's almost 8 billion. Sentence isn't great, try "Humans emerged 300,000 years ago, and have reached a population of almost 8 billion today". (note that English switches commas and decimal point in numbers compared to many other European languages)

@ Clayoquot & @ Mikenorton: more comments? Femke ( talk) 17:32, 25 January 2022 (UTC)

"Humans emerged 300,000 years ago, and have reached a population of almost 8 billion today" is much clearer. Good point about commas and decimal points. In English, 300.000 = 300. Cheers, Clayoquot ( talk | contribs) 17:39, 25 January 2022 (UTC)

Earth formed over 4.5 billion years ago. During the first billion years of Earth's history, the ocean formed and then life developed within it. Life spread globally and began to affect Earth's atmosphere and surface, leading to Earth's Great Oxidation Event two billion years ago. Humans emerged 300,000 years ago, and have reached a population of almost 8 billion today. Humans depend on Earth's biosphere and natural resources for their survival, but have increasingly impacted Earth's environment. Today, humanity's impact on Earth's climate, soils, waters and ecosystem has become unsustainable, threatening people's lifes and causing widespread extinction of other life.

I've changed that sentence, which looks good and incorporated another couple of changes. Firstly, I've reworded the 2nd sentence as I think that "developed" is better for the appearance of life than "formed", Secondly, I've cut down on the number of "Humans" in the 4th sentence.

It's a weird technicality but trace amounts of introduced microscopic life do exist on other planets, having been brought along on space probes due to the practical impossibility of 100% sterilizing them. It's not a large enough amount to matter in any significant way but it does mean that the statement "only planet known to harbor life" is technically incorrect. SpudNutimus ( talk) 17:36, 16 March 2022 (UTC)

Interesting point. I notice that we don't repeat this statement in the body of the article with a WP:reliable source. Do you have a reliable source that we can add with either statement? I'll have a look what my books about Earth say on the matter. I think the word harbor is sufficiently vague that having a few microbes on a rock doesn't really count as harboring... Femke ( talk) 17:53, 16 March 2022 (UTC)

I found this recent source that says Earth is the only planet to harbor life: https://iopscience.iop.org/article/10.3847/2041-8213/ab3a49/meta. That would at least make the statement a bit less strong, and more likely to be true. Do you have a source that says indigenous life. If we're being "technically correct", it's not quite certain that life on Earth is indigenous, right? If I'm not mistaken, introduction of life via a comet is still a plausible hypothesis for how life arrived on Earth. Femke ( talk) 18:02, 16 March 2022 (UTC)

The current image used to represent earth is The Blue Marble, and rightly so. However, the main version used is one scanned by NASA in 1972 which, as a result of poor processing, has inaccurate colors and does not do the Earth justice.

At the end of most film magazines used on the Apollo missions, there is a photograph of a color calibration chart. By calibrating the colors in The Blue Marble to match the colors on the chart one can better approximate what the astronauts actually saw when they took the picture. It is by this process that this alternate version of the photograph came to be produced. This new version of The Blue Marble was taken and re-cropped from the original AS17-148-22727 photograph, scanned by NASA's Johnson Space Center.

My proposal is that we let go of our personal attachments to the original purple earth, and update the official photographic representation of earth to something more accurate to real-life. Aaron1a12 ( talk) 21:11, 26 January 2022 (UTC)

I tend to the updated one. Its a nice compromise with having an old image. Nsae Comp ( talk) 21:38, 26 January 2022 (UTC)

I have to add something: shouldnt the picture be rotated to have north down, as originally taken? Nsae Comp ( talk) 04:06, 2 February 2022 (UTC)

I think the image of Earth in the Infobox should have North Africa and Arabia at the top and Antarctica at the bottom. This article is about Earth, not about the Apollo photos or Apollo astronauts travelling upside down (relative to Earth's geographic poles). The frame of reference should not be the "up" direction of an Apollo astronaut, which is opposite of convention. The fact that the Apollo astronauts' photo is upside-down relative to conventional depictions of the Earth is an obstacle to the general reader's understanding of Earth. The general reader of Wikipedia will be unnecessarily confused by Antarctica at the top of the image and North Africa and Arabia at the bottom of the image. An analogy: the article on gravity would not be improved by a photo of books on a bookshelf, taken by a photographer hanging upside-down from a ceiling. The conventional viewpoint is that shelves stop objects falling downwards, they do not usually stop objects floating upwards. Prioritising the photographer's unusual viewpoint over the conventional viewpoint could give the misleading impression that the books float in mid air and the shelf prevents books floating further upwards, when the reality is that the books will not float upwards and the bookshelf is actually preventing the books falling downwards. GeoWriter ( talk) 16:27, 2 February 2022 (UTC)

Agree with GeoWriter. It's not that important that we display what the Apollo crew saw. We want an immediately clear image of Earth. Femke ( talk) 17:59, 2 February 2022 (UTC)

With a black background surrounded by Wikipedia's white, the new image is less pleasing to my eyes as well.. Femke ( talk) 17:59, 2 February 2022 (UTC)

I understand that we shouldn't confuse the average reader and to that goal, it does become obvious that the conventional orientation of Earth should be used (north equals up.) Also, since the article is about Earth, and not The Blue Marble, it is essential that we illustrate Earth as close to real-life as possible. I can't count the many times flat-earthers have confronted me online about how "NASA can't settle on its CGI earth look" or "why do the ISS photos not match." Using better imaging technology, NASA/JSC/ASU rescanned this photograph about 40 years after 1972, and I see no reason to still use the badly processed original. Aaron1a12 ( talk) 03:36, 3 February 2022 (UTC)

Looks good, refreshing and eyes opening like Wikipedia should. Its not a map afterall. Nsae Comp ( talk) 13:54, 3 February 2022 (UTC)

Portraits nicely that Earth is not bound to human convention and is more than what we want it to be. Beautyful. I find it good because it is a portrait, I am not asking for rotating all images of Earth like that, but as a portrait as a whole (e.g. not as a map) it does not need to fulfill a use like quick orientation or not to be distracting from something conveyed by a depiction of Earth e.g. in infrared or any other analysis of Earth. The example of shelfs and books well, a shelf works by standing by gravity, but Earth does not care how we orient it, in fact there is no difference, because the reference frame is missing like in the shelf example, in that picture you have also a floor and ceiling, thats something that is missing here so you can indeed rotate it without distroying its correctness. Its like having a picture without reference frame of a shelf that you can turn on its head and is built to still be useable. Nsae Comp ( talk) 14:05, 3 February 2022 (UTC)

Your example of the shelf is like having a picture of Earth and the Moon and turning only Earth on its head, then we most certainly have a problem, because then the reference frame is there. Nsae Comp ( talk) 14:08, 3 February 2022 (UTC)

I do like the idea of breaking with preconceived notions of what Earth should look like, and it's certainly refreshing. In space, there is no up, and making north up is just a preference mostly decided by Northern European explorers. I'm split. Aaron1a12 ( talk) 22:01, 3 February 2022 (UTC)

I prefer conventional orientation. If we're to do otherwise, having Antarctica at the top would be just as arbitrary. The astronauts would see Earth as lying on its side, if they were sitting/lying parallel to the moon's orbital plane. Dhtwiki ( talk) 02:37, 4 February 2022 (UTC)

P.S. I'm okay with the new, lighter image, as well. Dhtwiki ( talk) 02:38, 4 February 2022 (UTC)

Too bad, it was really refreshing and proper. Maybe one day people will see Earth in any orientation from space as they want. Nsae Comp ( talk) 03:59, 5 February 2022 (UTC)

Suggesting a new orientation isn't advocating for something that's "proper", as that word signifies a conventional orientation or attitude. "Refreshing" might not be the word people would use, if they are merely confused by a new orientation, when they're looking for clarity, which is likely when they're consulting an encyclopedia. We are limited in how many images we can display here; and, as I said, an upside-down image isn't showing us what the astronauts saw. It's just as arbitrary as the usual "right"-side-up. Dhtwiki ( talk) 22:20, 5 February 2022 (UTC)

The mean anomaly at Epoch J2000 should read 357.517 instead of 358.617 degrees.

I have reverted these edits by Nsae Comp in part because they introduced a number, 365.2421897, that is not in the cited source, and then converted that to some kind of year. It is not clear that astronomers normally make such a conversion.

Also it claims this number is the "synodic period". I copy a definition of synodic period from page 656 (in the glossary) of Explanatory Supplement to the Astronomical Almanac 3rd ed., edited by Urban and Seidelmann and published by University Science Books in 2013.

synodic period: the mean interval of time between successive conjunctions of a pair of planets, as observed from the Sun; or the mean interval between successive conjunctions of a satelllite with the Sun, as observed from the satellite's primary.

Since the only celestial bodies being discussed are the Earth and the Sun, and the definition of synodic period requires three celestial bodies, the definition cannot apply. Jc3s5h ( talk) 13:52, 5 June 2022 (UTC)

Well as I wrote in the edit comment, the problem is with the infobox template, which does not know a category for tropical year. So I was merely trying to add tropical year with the help of the "synodic year" category of the infobox template. I agree that all definitions of synodic "year" are like the one cited above. But since synodic, as in synodic rotation does indeed just mean the solar day it is not absurd to also understand synodic in connection with "year" in the sense of the solar/tropical year. I have even seen the use "synodic year" for "tropical year", but since I am not being able to provide an in depth source I have to concede to the critique, that useing the "synodic_period" category of the infobox is misleading. Nsae Comp ( talk) 16:15, 5 June 2022 (UTC)

With other words, if someone can find a way to have the tropical year in the infobox, that would be great, because it is absurd, that the infobox only features the sidereal year. Nsae Comp ( talk) 16:17, 5 June 2022 (UTC)

Your calculation is correct but it assumes a perfectly spherical Earth with uniform mass when in reality, the Earth is an oblate spheroid, slightly wider at the diameter than the poles and the density of the Earth is probably (not a geologist) non-uniform. The source that is cited for the Earth's mass would've used a more advanced method for calculating the mass resulting in it being more accurate. QuinticFormula 🏳️‍🌈 (talk) 11:36, 16 June 2022 (UTC)

User:Dhtwiki reverted my IABot edits, saying "Adds to clutter, download and setup times; when links are live accomplishes nothing; when links are dead, it's a likely time to reevaluate or update references; linkrot policy doesn't support mass addition of these archive links." I don't really agree that it is just clutter, when a lot of the links are archived for the first time and it doesn't really hurt to have these links in. What do you guys think? CactiStaccingCrane ( talk) 00:19, 31 July 2022 (UTC)

That revert seems a rather single-minded opinion that prevents prolonged verifiability. I don't see how Dhtwiki can in good conscience revert a standard practice on WP like that—If they have an issue with it, bring it up in a community wide discussion. Until then, it is not an improvement to revert such an edit. Aza24 (talk) 02:54, 31 July 2022 (UTC)

How does it prevent prolonged verifiability? And how is it standard practice? IABot itself, when running by itself, only adds links when they're dead? There are a number of editors who think running this program, without any further checking or curation of the pages affected, think they're helping; but no one can offer much besides vague assertions that it somehow improves things. How exactly? The archive links are there to be linked to if the original dies; setting the archive links doesn't cause that to happen. I think it's a waste of time and resources, and when it adds tens of kilobytes to an article and many extra links is detrimental. Dhtwiki ( talk) 05:07, 31 July 2022 (UTC)

I agree with some of the point, but I disagree with your premise. Yes, the default option of IABot is to add dead links only, but there's also a checkbox that allows you to add archive to all the links. A lot of the links are archived for the first time this way, so waiting until the links are dead before using IABot is not a great idea as we may lose the source forever and unable to verify the information. If you argue that it would clutter up the wikitext, then sorry, but our standard referencing practice has already make the wikitext a lot harder to read already. Stripping archive links doesn't help much with that. CactiStaccingCrane ( talk) 05:58, 31 July 2022 (UTC)

Don't have an opinion here, but all links added to Wikipedia are automatically archived if I'm not mistaken. So these archive links can be added at a later point. Femke ( talk) 07:39, 31 July 2022 (UTC)

Right. See WP:PLRT, which is a section of Wikipedia:Link rot: "Links added by editors to the English Wikipedia mainspace are automatically saved to Wayback Machine within about 24 hours (nb. in practice not every link is getting saved for various reasons)." Adding the archive links isn't needed to ensure that the archives are created. Note the quoted expception ("in practice not every link is getting saved for various reasons"); but it isn't necessarily so that adding links to archive snapshots overcomes that. Dhtwiki ( talk) 19:55, 31 July 2022 (UTC)

Well, I changed my mind. I won't check the box when I archive the page links again, unless if the bot doesn't archive certain essential links for whatever the reason. CactiStaccingCrane ( talk) 11:50, 1 August 2022 (UTC)

No, too early to judge whether this study will gain wide acceptance. Same as for almost all newly published work. Mikenorton ( talk) 15:27, 17 June 2023 (UTC)

A quick read of the paper suggests that the Washington Post has got its knickers in a twist, but no; their use of English is a little weird but they do accurately summarise the paper. The Nature paper suggests that the evidence is the earth formed very quickly and within 3 million years after the Solar system was formed. This would make it much older than believed at present. An age of creation of only 3 million years ago is more akin to young creationist thinking and would neither allow time for life to form and differentiate nor for the decay of radio-isotopes which give us relatively accurate ages of many rock strata - but that is absolutely not what the paper says. I would wait to see the reaction of cosmologists to the paper and it may well be worth adding then with suitable caveats that this research suggests an older age of formation, not a younger one.   Velella   ^{Velella Talk}   18:49, 17 June 2023 (UTC)

In fairness to Drbogdan , I misread the original addition to the article, so apologies for what turns out to have been something of a knee jerk reaction. But...... if I could read it the wrong way, then I guess others could too. I live in a house built on 750 million year old rocks and the prospect of them not even existing shook me to my literal foundations. So, perhaps with clearer phrasing, and as noted above, it probably will have a place in the article. (Time to go back to my plants I suspect!)   Velella   ^{Velella Talk}   18:57, 17 June 2023 (UTC)

The "43" in the following text should be changed to half that, "21.5", a necessary change that is evident from the Earth Physical Characteristics near the top of the page. Measurements made to the center of mass are radiuses, not diameters.

Due to Earth's rotation it has the shape of an ellipsoid, bulging at its Equator, reaching 43 kilometers (27 mi) further out from its center of mass than at its poles. ^{[1] [2]} RMMentock ( talk) 16:23, 21 September 2023 (UTC)

 Partly done: The source specifically mentions the diameter, and while I think it'd be reasonable to halve it when referring to radius, I've instead just gone for rewording the sentence to keep the 43 km, but clarify that it's in reference to the diameter. Closing this because I think this solves the issue, reopen if you have any objections. Thanks,  BelowTheSun  ( T• C) 20:06, 21 September 2023 (UTC)

Hi there currently the first sentence says "to harbor life." While I am technically fine with the reintroduced shorter and simpler phrasing, though I feel urged to defend the previous wording of "where life developed and found habitability.".

I quite strongly feel it gives a better understanding of what a planet and Earth in this case is for life, "harbour" is almost a text filler in comparison. Afterall the Moon has for some days allready "harboured" life, even space does. But develop and being habitable is a deeply planetary characteristic.

A compromise would be to reduce linking and remove the link to life. But even that doesnt feel being too much. (@ Brandmeister) Nsae Comp ( talk) 21:24, 24 August 2023 (UTC)

 Not done for now: I agree that the phrasing is ambiguous, but I think the proposed wording is still ambiguous/clunky. Which body is the it in "its rotation"? Also, tidal locking can happen regardless of ocean tides, yes? Being generous, I would interpret the present sentence to mean "through [[the process of]] tidal locking, [[this list of things happen]]." Not opposed to changing it, just not sure about this proposed alternative. Brevity is to be encouraged in an article's lead. The Savage Norwegian 18:19, 5 November 2023 (UTC)

It’s not a question of ambiguous phrasing. The existing sentence pretty unambiguously states as fact something that is patently totally incorrect. This is inexcusable in the lead section of an article as important as ‘Earth’. However one interprets ‘it’ (and it could only be the earth – the moon’s relative rotation having already slowed to a standstill), none of the listed effects is due to tidal locking. The Old Font ( talk) 14:45, 9 December 2023 (UTC)

 Done – changed to The Moon’s gravity helps stabilize Earth's axis, and also causes tides which gradually slow Earth's rotation. As a result of tidal locking, the same side of the Moon always faces Earth. Ocean tides are in fact by far the main contributor to the tidal locking seen in the Earth-Moon system, so this phrasing is fine. Tollens ( talk) 00:30, 11 December 2023 (UTC)

Earth is the third planet from the Sun and the only astronomical object known to harbor life. It is the densest planet in the Solar System and the largest and most massive of the four rocky planets. About 29% of Earth's surface is land, with the remaining 71% covered with water and much of Earth's polar regions covered in ice. Earth's interior is active with a solid iron inner core, a liquid outer core that generates Earth's magnetic field, and a convective mantle that drives plate tectonics. Earth formed over 4.5 billion years ago. Within the first billion years of Earth's history, life appeared in the oceans and began to affect Earth's atmosphere and surface. Since then, the combination of Earth's distance from the Sun, physical properties and geological history have allowed life to evolve and thrive, including more than 8 billion humans. Earth is orbited by one permanent natural satellite, the Moon, which orbits Earth at 384,400 km (1.28 light seconds) and is roughly a quarter as wide as Earth. This view of Earth was taken by NASA's Lunar Reconnaissance Orbiter in 2015, from above the Compton crater on the Moon. Photograph credit: NASA Recently featured: Archive More featured pictures

A bunch of the sentences and statements in the article are unsourced, and considering this is an FA I feel like it has to be dealt with at some point. Blue Jay ( talk) 12:32, 11 January 2024 (UTC)

Considering that the article has about 600 sentences, you might want to be a little more specific... Dhrm77 ( talk) 15:20, 11 January 2024 (UTC)
