Document Summary
The climate system: the climate system include the, atmosphere, hydrosphere, geosphere, biosphere, cryosphere (ice and snow) Components of the climate system: hydrosphere, global ocean (circulates by two major current systems, continental water (lakes, rivers, and groundwater, thermohaline ocean currents, warm, fresh, shallow current (less dense, cold, salty, deep current (more dense) Just like mantle convection, this system can move heat from one place to another: cryosphere. Air is a mixture of many discrete gases. Nitrogen and oxygen make up 99% of the clean dry air. Co2, although present in minute amounts (0. 0338%), greatly influences heating of the atmosphere. O3, and the total: 255 k earth thermal radiation going out (absorbed by h2o and co2, but not o2 and o3) [in the infrared spectrum, earth"s albedo (31%) is energy reflected by clouds (22%) and earth"s. Earth"s atmosphere (20%) and the surface (49%: to achieve radiation balance, earth radiates the sum of the radiation surface (9%).
