Document Summary

Processes controlling exchanges of carbon between oceans and atmosphere: there is a net uptake of carbon in the ocean more comes in than goes out process that exchanges the carbon from the atmosphere and the ocean is diffusion. Short-term organic carbon cycle emphasis on the interactions between the atmosphere and the biosphere: terrestrial and marine components. Long-term organic carbon cycle emphasis on the formation and destruction of fossil fuels and other sediments containing organic carbon. What is the source of fossil fuels? organic sedimentary rock that consist of the lithified remains of plants or animals. Coal is an organic sedimentary rock made up of decomposed and compacted plant remains. Long-term inorganic carbon cycle emphasis on calcium carbonate (limestone), by far the largest of the carbon reservoirs this cycle is linked to the carbonate-silicate cycle, supplying the calcium ions necessary from the formation of limestone. Caco3 (calcium carbonate) this is limestone and is by far the largest reservoir in.
