Carbonate rocks {Ans: Carbonate rocks, such as limestone and chalk, and deep-ocean sediments are by far the biggest carbon store. Most of the carbon that is not stored in rocks and sediments is found in the oceans as dissolved CO Carbon storage in the atmosphere, plants and soils is relatively small. However, these stores play a crucial part in the carbon cycle. They also represent most of the carbon in circulation at any one time.}The processes of the Water Cycle {Ans: The principal flows in the water cycle that link the various stores are: precipitation, evaporation, transpiration, run-off, infiltration, percolation and throughflow.}Carbon cycle Principle carbon stores {Ans: Principal carbon stores ... The global carbon cycle consists of a number of stores or sinks connected by flows of carbon. The principal stores are: the atmosphere, the oceans, carbonate rocks, fossil fuels, plants and soils. Carbon moves between these stores in an unending cycle. Atmosphere = 600 (Carbon store in billion tonnes) Oceans = 38, 700 Sedimentary (carbonate) rocks = 60, 000 - 100, 000, 000 Sea floor sediments = 6, 000 Fossil fuels = 4, 130 Land plants = 560 Soil/peats = 2, 300}What is the slow Carbon
