Carbon sinks are natural or artificial reservoirs that absorb and store carbon dioxide from the atmosphere. Calcium carbonate, sedimentary rocks, and petroleum are all examples of carbon sinks. Calcium carbonate is found in seashells and other marine organisms, and it can absorb carbon dioxide from the atmosphere and convert it into solid calcium carbonate. Sedimentary rocks are formed from the accumulation of sediments, and they can contain organic matter that can absorb carbon dioxide. Petroleum is a fossil fuel that is formed from the remains of ancient plants and animals, and it can absorb carbon dioxide from the atmosphere and store it underground.
