Document Summary

Climate: a measure of the ag pattern of variation in temp, precipitation, and other meteorological variables in given region over long period of time. Biomes: the world"s major communities, classified according to the pre dominant vegetation and characterized by adaptation of organisms within it. Temperate shrub land and woodland; hot, dry summer; cool, moist winter; dense vegetation, vulnerable to fire evergreen, fire prone due to brush buildup among biomass. Air circulation driven by solar radiation and rotation of earth a. That heat causes air to rise and that air is moist. As it rises it cools, then water starts to precipitate towards equator. Some air moves north and south (north) air cools and starts to descends, its dry, cool air descending at 20 degrees north and south of equator north and south of equator. Pulled toward equator being pulled from east to the west. Coriolis effect due to earths rotation around its axis.
