Document Summary
Earth spinning on a 23. 5 degree tilt: the lower angles have a greater area of sunlight, more spread out = less hot, equator has smaller area of sunlight, heat is more focused so its hotter. Greenhouse effect: solar radiation from the sun is captured in the earths atmosphere which warms the planet, solar radiation absorbed by clouds, emits infrared radiation, absorbed by greenhouse gases which return to earth warmed. Uneven distribution of landmasses: provides a broad range of temperature at different latitudes. Wind lags behind the earths rotation: lags more where earth spins faster (larger circumference) Generally: high latitude westerlies, mid strong trade winds, equator little to no wind (doldrum) Coriolis effect: deflection of wind due to differences in rotation speed. Upwelling: surface water moving away from shore and deeper water bringing nutrients in to replace it. Rotation of earth on its axis: circadian rhythms, individual behaviour (diurnal [daytime], nocturnal [nighttime], crepuscular [switch b/w day n night])
