Elements : The Carbon Cycle Quiz

Quiz
*Theme/Title:	The Carbon Cycle
* Description/Instructions
The carbon cycle is the biogeochemical process by which carbon is exchanged through Earth’s oceans, atmosphere, ecosystems and geosphere. Combined with the water cycle and the nitrogen cycle, the carbon cycle comprises a series of events that are essential to sustaining life on Earth. Even though carbon dioxide is a very small component of the atmosphere, it plays a significantly large role in the energy balance of the Earth. The atmosphere is continuously exchanging carbon dioxide with the oceans. Regions that produce carbon dioxide are called sources. Regions that absorb carbon dioxide are called sinks. Life processes are fueled by carbon compounds that are oxidized to carbon dioxide. This, in turn, is exhaled by animals and absorbed by plants during photosynthesis to build new compounds. Fossil fuels such as coal, petroleum, and natural gas produce carbon dioxide when burned. Over time, the amount of carbon dioxide is increasing as a result of the burning of fossil fuels.
