a)The five most important biogeochemical cycles are the oxygen cycle, nitrogen cycle, carbon cycle, sulphur cycle and the sedentary cycle. These five cycles can be classified into pools. Active pools are free flowing cycles controlled by life processes such as photosynthesis. Storage pools are segregated bodies controlled by physical processes such as, volcanic eruptions or earthquakes.

Oxygen cycles through the environment in three major forms; gaseous atomic oxygen, and the molecular compounds, H2o and co2 respectively. Oxygen is a highly reactive element that is necessary for organic cellular respiration. An interesting note is the process of oxidization. As previously stated, Oxygen is highly reactive and many inorganic metals and compounds (not the noble metals) will react with the surrounding Oxygen in the atmosphere. This process will alter the surface layer and decompose the surface in a process of oxidization. Sedentary Cycle is the slowest cycle measured in millions of years. This process is characterized as a non-gaseous elemental cycle consisting of solid minerals, metal and base elements. Due to the heavier nature of these elements coupled with higher boiling and evaporation point, elements of the sedentary cycle are mostly found in the earths oceans and land mass as long term pool storage. The physical processes that will free material from this long term storage are volcanic and wind activity. Interesting note, the vast majority of…
