Detailed explanation-1: -Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles . Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
Detailed explanation-2: -The geological carbon cycle Carbon may be stored for long periods of time in the atmosphere, bodies of liquid water-mostly oceans-ocean sediment, soil, rocks, fossil fuels, and Earth’s interior.
Detailed explanation-3: -Coal, oil, natural gases, methane hydrate and limestone are all examples of carbon sinks. After long processes and under certain conditions, these sinks have stored carbon for millennia.
Detailed explanation-4: -Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.
