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.
Though only a small amount of the atmosphere is made of CO2, this is still a huge amount in weight and volume. It is reasonable to wonder what the major sources are. The greatest amount of carbon dioxide is locked up in plants, rocks, and the oceans. It should not be surprising that these each contribute more CO2 emissions than any other sources.
