The carbon cycle is a series of processes that involve carbon moving through the environment, living organisms, photosynthesis, and returning to the atmosphere. These cookies ensure basic functionalities and security features of the website, anonymously. Necessary cookies are absolutely essential for the website to function properly. CO2 is exchanged between the atmosphere and oceans with CO2 dissolved in surface water and a return of CO2 to the atmosphere by evaporation. Carbon is returned to the surface of the Earth as acid rain to start the cycle again.įind out about the processes and pathways of the carbon cycle. CO2 is absorbed by phytoplankton by photosynthesis after which it is transformed into carbohydrates and stored in their tissues.Respiration by living organisms releases CO2 to the atmosphere. Although carbon storage is small in the atmosphere, plants and soil they are a very important element of the carbon cycle. The transfer of carbon between the oceans, atmosphere, soils and living organisms is ten to one thousand times faster than the slow carbon cycle. Fossil fuels such as coal, oil and gas store carbon for millions of years. Water flowing over sedimentary rock dissolves it transporting carbon to the oceans. Sedimentary rocks near the surface release CO2 as they are chemically weathered. CO2 that was stored in the rock is released into the atmosphere through volcanic eruptions. Oceanic crust, containing sedimentary rock, is subducted causing the crust to melt. This carbon is usually stored in rocks for around 150 million years. Over millions of years, these organisms become compressed and become carbon-rich sedimentary rock. When they die they accumulate on the ocean floor. Marine organisms, such as shellfish and phytoplankton, build their shells by combining calcium with carbon. The long carbon cycle involves the long-term storage of carbon. The carbon cycle is most easily studied as two interconnected subcycles: One dealing with rapid carbon exchange among living organisms One dealing with long-term cycling of carbon through geologic processes Although we will look at them separately, it's important to realize these cycles are linked. ![]() One is the slow carbon cycle, the other, the fast. There are two elements to the carbon cycle. Carbon Stores The slow carbon cycle – storage ![]()
