Document Summary

Biomes: major type of plant community. Whys climate so important to biodiversity and environment: gives rise to climate zones. These choose which forms of life occur where. Roles of wind in climate: acts as earth"s circulatory system for: Set of physical properties of the troposphere at any given time and place: temperature, pressure, humidity, precipitation. Two things regulate a place"s climate: average temp, average precip. These factors are influenced by: latitude, altitude, ocean and air currents, seasons. Climate affects: what lives where, how organisms live. Patterns of air circulation over earths surface influence: temperature, precipitation. Uneven heating of earth"s surface: equator vs. poles. Rotation of earth on its axis: air circulation. Air heated much more at equator (sun ray"s direct year round) than at poles. (rays at an angle, spread out. Warm equatorial air rises and spreads north or south.
