Document Summary
The study of interactions between organisms and their environment. Seasons happen because of the tilt of the earth"s axis! Solar energy atmospheric circulation patterns + earth"s rotation prevailing winds ocean currents varying distributions of climate patterns organisms adapt to local abiotic conditions biomes. Equator receives direct solar radiation (radiation hits atmosphere at 90 . More north/south of equator solar radiation hits at an angle (greater or less than 90 ) in keeping with how far from the equator it is varying levels of absorbance and heating. Solar energy heats air mass at earth"s surface (at the equator) Risen air cools + releases moisture precipitation. Cool air is deflected north or south by the rising warm air under it. Cool, dry air sinks to surface 30 n or s of equator. Cool air at surface absorbs moisture from the ground deserts at lat.
