Document Summary
Lec 3: the physical environment and the biosphere. Determines where organisms can live, and the resources that are available to them. Example: if you take a fish and out it in a desert, it won"t survive. **there is more diversity in all of these around the equator. Concept 2. 1: most fundamental component of the physical environment. Weather: current conditions (temp. , precipitation, humidity, etc. Climate: long-term description of weather based on averages and variation measured over decades. **extreme events especially important due to their impacts on mortality. Sun rays are spread out more in the north than the equator. Because of angle that rays hit north and south poles, the more atmosphere it has to penetrate more radiation is absorbed/reflected before it reaches the earth"s surface. Warmer air is less dense than colder air. Warm air rises (uplift) as it rises higher, it expands left and right.
