Document Summary
Coined in 1869 by ernst haeckel; he read the origin of species. Described ecology as, the study of all those complex interactions referred to by darwin from charles darwin as the conditions of the struggle for existence". Caused by the tilt of earth"s axis. North and south poles receive indirect sunlight , equator receives direct sunlight. Solar energy---atmospheric circulation patterns+earth"s rotation---prevailing winds---ocean currents---varying distributions of climate patterns---organisms adapt to local abiotic conditions---biomass. Velocity of earth"s rotation (fastest at equator) Air mass not moving in either direction (same velocity as earth) Air mass moving away from equator (faster than the earth beneath it and is deflected to the east. The direction of prevailing winds at earth"s surface is determined by: Rise of warm air mass that results from latitudinal gradients in solar energy input. Prevailing winds can also cause water to move vertically. Provide three-dimensional structure, modify microclimates near the ground. Had permafrost; stays frozen for most of the year.
