Document Summary
The biosphere: plants, draws down co2 for photosynthesis, affects albedo, animals, release co2 and methane, biological pump, process of moving co2 from the atmosphere to the lithosphere, interaction of biosphere, atmosphere, hydrosphere, and lithosphere. The cryosphere: all the frozen material on earth, glaciers, snow, tundra, permafrost. Ice covers ca ~9% of land surface: most land surfaces albedo ~ 15-25, snow/ice albedo~ 40-90% The lithosphere: tectonics affects climate in several ways, continental position, continental size. Big continent means it"s hard for rain to reach the middle of the continent: collision zone uplift. Rain comes in from the coast and tries to go over mountains, in. Rain shadows order for it to move over the mountains it must rise, when it rises it loses moisture causing the other side of the mountain range to get little to no rain. Thin strip of land that connects two larger land masses. Instrument and historical records only go back so far.
