A-Level Geography Carbon Cycle Questions and Answers(A+ Solution guide)

1. Carbon dioxide 2. Methane 3. Calcium carbonate - Name 3 different forms of carbon. The mantle - Where is carbon originally stored? At constructive and destructive plate boundaries as well as hot-spot volcanoes. - Where does carbon escape from the mantle? 1. Atmosphere 2. Oceans 3. Biomass as living or dead decaying organisms 4. Carbonate rocks - Name 4 examples of were carbon is stored. It is stored in the crust and uppermost mantle in both inorganic and organic form. - Where is carbon stored in the Lithosphere? Fossil fuels like coal, oil and natural gas. - Name an example of an inorganic deposit of carbon in the Lithosphere. Litter - Name an example of an organic deposit of carbon in the Lithosphere. - Marine sediments and sedimentary rocks - Soil organic matter - Fossil fuels - Peat - What stores is carbon distributed between in the Lithosphere?When organisms die, their dead cells, shells and other parts sink into deep water. Decay releases carbon dioxide into this deep water. Some material sinks right to the bottom, where it forms layers of carbonrich sediments. Over millions of years chemical and physical processes may turn these sediments into rocks. This part of the carbon cycle can lock up carbon of millions of years. - Explain how carbon can be stored in the Hydrosphere. 1. Surface layer 2. Intermediate and the deep layer of water 3. Living organic matter (fish, plankton, bacteria) - Name the 3 layers of the oceanic stores
