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.
Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called âsinksâ. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.
