Exploring the Environment: Earth on Fire

The carbon cycle is one of the biogeochemical cycles. This site contains information about the movement of carbon, in its many forms, between the biosphere, atmosphere, oceans, and geosphere. The site describes the cycle with its various sinks, or stores, of carbon and processes by which the various sinks exchange carbon. A diagram illustrates the carbon cycle and can be expanded for group viewing. The site is also supported by links to a glossary, references, and related topics.
