Stratosphere
|
The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. It is stratified in temperature, with warmer layers higher up and cooler layers farther down.
Basically the second layer of atmosphere from the ground (6-28 miles up). Link to picture of stratosphere: http://en.wikipedia.org/wiki/File:EarthAtmosphereBig.jpg |

Sulfur Cycle
|
The essential steps of the sulfur cycle are:
Mineralization of organic sulfur to the inorganic form, hydrogen sulfide: (H2S). Oxidation of sulfide and elemental sulfur (S) and related compounds to sulfate (SO42–). Reduction of sulfate to sulfide. Microbial immobilization of the sulfur compounds and subsequent incorporation into the organic form of sulfur. Basically Sulfur is one of the constituents of many proteins, vitamins and hormones. It recycles as in other biogeochemical cycles.
