Document Summary
Earth"s climate varies by latitude and season is changing rapidly. Most signi cant in uence on the distribution of organisms on land and in the oceans is climate: long-term prevailing weather conditions in a given area. *four physical factors: temperature, precipitation, sunlight and wind are particularly important aspects of climate. Global climate patterns are largely determined by the input of solar energy and earth"s movement in space. This warming establishes the temperature variations, cycles of air and water movement, and evaporation of water that causes dramatic latitudinal variations in climate. Climate patterns can be modi ed by many factors: seasonal variation in climate, large bodies of water, and mountain ranges. Earth"s tilted axis of rotation and its annual passage around the sun cause strong seasonal cycles in middle to high latitudes. In addition to these global changes in day length, solar radiation and temperature, the changing angle of the sun over the course of the year affects local environments.
