Detailed explanation-1: -The largest reservoir of the Earth’s carbon is located in the deep-ocean, with 37, 000 billion tons of carbon stored, whereas approximately 65, 500 billion tons are found in the globe.

Detailed explanation-2: -Carbon cycles between reservoirs or sinks in the Carbon Cycle. The lithosphere stores the most carbon, some of which is found in fossil fuels. The hydrosphere is the second largest reservoir, followed by the atmosphere, and then the biosphere.

Detailed explanation-3: -Carbon is stored in the lithosphere in both inorganic and organic forms. Inorganic deposits of carbon in the lithosphere include fossil fuels like coal, oil, and natural gas, oil shale, and carbonate based sedimentary deposits like limestone.

Detailed explanation-4: -The lithosphere is the upper, rocky layer of the Earth’s crust. Weathering of rocks by rain releases ions like calcium that flow to the ocean. There they combine with carbonic acid to form calcium carbonate in shelled animals.

Detailed explanation-5: -The five major carbon reservoirs are: Rock, Atmosphere, Oceans, Terrestrial Biosphere, and Fossil Fuels.
