Basically, carbon sinks are holding tanks for carbon or carbon compounds, like carbon dioxide (CO2). One of the largest reservoirs of carbon is the Earthâs hard rock crust. Over the eons sedimentary rocks were formed that contain loads of carbon compounds, including the hydrocarbons that we now use as fossil fuels.
The Carbon Cycle. Where is most of the Earth's carbon located and in what form? Most of the world's carbon is found in the ocean as either carbon dioxide or calcium carbonate. Shells of most sea creatures are composed of calcium carbonate. Once these creatures die their shells turn into limestone and as limestone erodes the carbon is released into the atmosphere or bodies of water.
