How the Geosphere Rocks Climate

Over millions of years, carbon dioxide, a greenhouse gas in the atmosphere, becomes sequestered in rocks like limestone and fossilized plants that may become coal and other fossil fuels. The carbon is taken out of the faster pattern of carbon cycle processes and is thus sometimes called the slow carbon cycle. ... so new species can have a new ...
