Compare the effects on the carbon cycle of natural processes such as volcanism and human activities
such as burning fossil fuels.

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
