I find the traditional explanation for moss growth on the northern part of trees somewhat puzzling. Is the air and bark temperature difference between a northern and all other parts of a tree that big? I suspect it to be within fractions of a Celsius degree at most, if not identical which doesn't seem to be enough to make a difference. Same for humidity. The distance difference in such cases is typically between several to several tens of centimeters.
A similar explanation for ant hills on the southern side also puzzles me. If the sun rises at the east, setting at the west, it would be the eastern side that receives most sunlight, being effectively more warmer rather than southern side. A southern side appears to be roughly perpendicular to most sunrays and thus less insolated than the eastern side. Thanks. 212.180.235.46 ( talk) 21:12, 19 May 2023 (UTC)
