When precipitation happens, this falls as carbonic acid, commonly known as acid rain. Carbon can leave the atmosphere mixing with water vapour. The input to the ocean store is through absorption via gas exchange with the atmosphere. Fast carbon cycleĬarbon is stored in the ocean as dissolved CO2 in the water and carbon compounds in marine organisms. Gaseous - found as carbon dioxide (CO2) and methane (CH4) in the atmosphereĪ diagram of the carbon cycle focusing on where carbon dioxide and methane are found in the cycle. Organic - found in plant material and living organisms Inorganic - found in rocks as bicarbonates and carbonates There are three forms of carbon found in the carbon cycle. What forms of carbon are in the carbon cycle? In 2015, 195 countries adopted the first legally binding global climate deal at the Paris Climate Conference (COP21). With more carbon being emitted than stored, the carbon cycle is pushed out of balance. Burning fossil fuels releases carbon dioxide (CO2) into the atmosphere and adds to the greenhouse gases that trap heat, warming the Earth. Since then, the balance of the carbon cycle has been affected by the increasing use of energy. The carbon cycle was first described at the end of the eighteenth century by Antoine Lavoisier and Joseph Priestly.

Carbon stores are where the carbon is stored, and fluxes are the movement/transfer of the carbon between stores. Carbon is stored within the atmosphere in land and in oceans, and is moved by various processes. The key carbon cycles operate at the terrestrial, atmospheric and oceanic levels. The carbon cycle is the movement of carbon between the different reservoirs on the earth.
