Document Summary
Unit 1 cont"d: the biosphere (chapters 2 & 3) Climate is a fundamental component of the physical environment. Atmospheric and oceanic circulation patterns establish global patterns of temperature and precipitation. Regional climates are influenced by mountains, oceans and vegetation. Climate is a fundamental component of the physical environment a. Climate is based on long-term patterns of temperature, wind and precipitation. Atmospheric and oceanic circulation patterns establish global patterns of temperature and precipitation temperature and precipitation a. Regional climates are influenced by mountains, oceans and vegetation a. Albedo: amount of solar radiation reflected from surface. Influenced by type of vegetation as well as soil and topography. Biome: a large-scale biological community that is shaped by its physical environment. Seasonal variations in precipitation and temperature patterns determine global distributions of biomes. Convergence: evolution of a similar trait among distantly related species in response to similar selection pressures. Freshwater biological zones vary with water characteristics a.
