Environmental geology may be defined as the interaction of humans with their – fundamentally geological – environment. The environment can be considered to consist of both the constituents of the earth itself (rocks, sediments, and fluids) and its surface and the processes that operate to change it through time.
In the geological carbon cycle, carbon moves between rocks and minerals, seawater, and the atmosphere. Carbon dioxide in the atmosphere reacts with some minerals to form the mineral calcium carbonate (limestone). This mineral is then dissolved by rainwater and carried to the oceans.
