How does deforestation affect biogeochemical cycles? Why are biogeochemical cycles important to ecosystems? What are some examples of biogeochemical cycles? How is evaporation related to humidity?
How can condensation heat the atmosphere? How can condensation be observed? What are some examples of precipitation? The carbon cycle is easiest to understand in terms of its processes and how carbon is converted. The three key processes and the conversions are shown in the table below. The carbon cycle Carbon is an essential element for life on Earth.
Combustion burning. They will best know the preferred format. When you reach out to them, you will need the page title, URL, and the date you accessed the resource. If a media asset is downloadable, a download button appears in the corner of the media viewer. If no button appears, you cannot download or save the media.

Students sort everyday objects into carbon and non-carbon categories to learn that almost all objects contain carbon. Students use labels and arrows to represent processes that move carbon from one reservoir to another.
Students collaboratively finalize their carbon cycle model as a class, with a focus on educating their peers on how carbon moves through various reservoirs on Earth, where energy is stored, sourced, and released, and the impacts of carbon on the cycles. Join our community of educators and receive the latest information on National Geographic's resources for you and your students.

Image Quinault River Rainforest Full of living entities, and the formerly living, the temperate rainforest at the Quinault River in Olympic Peninsula, Washington, and places like it are rich reservoirs of carbon. Forest Service now has a powerful way to view near-real time fire detection from NASA satellite data that they can include in their hourly air quality forecasts. New NASA research shows that by releasing heat and moisture through a large hole in sea ice known as a polynya, the exposed ocean fuels the formation of more clouds that trap heat in the atmosphere and hinder the refreezing of new sea ice.
Carbon is a fundamental part of the Earth system. Carbon moves from the atmosphere to the land, ocean, and life through biological, chemical, geological and physical processes in a cycle called the carbon cycle. On the short time scale, the carbon cycle is most visible in life.
Plants on land and in the ocean convert carbon dioxide to biomass like leaves and stems through photosynthesis. The carbon returns to the atmosphere when the plants decay, are eaten and digested by animals, or burn in fires. Because plants and animals are an integral part of the carbon cycle, the carbon cycle is closely connected to ecosystems.
