A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases. Globally, the two most important carbon sinks are vegetation and the ocean. [ 3 ] Soil is an important carbon storage medium.
Carbon sequestration is part of the natural carbon cycle by which carbon is exchanged among the biosphere, pedosphere (soil), geosphere, hydrosphere, and atmosphere of Earth. [citation needed] Carbon dioxide is naturally captured from the atmosphere through biological, chemical, or physical processes, and stored in long-term reservoirs.
Carbonatite (/ kɑːrˈbɒnəˌtaɪt /) is a type of intrusive or extrusive igneous rock defined by mineralogic composition consisting of greater than 50% carbonate minerals. [ 1 ] Carbonatites may be confused with marble and may require geochemical verification. Carbonatites usually occur as small plugs within zoned alkalic intrusive complexes ...
At the carbonate compensation depth, the rate of dissolution exactly matches the rate of supply of CaCO 3 from above. At steady state this depth, the CCD, is similar to the snowline (the first depth where carbonate-poor sediments occur). The lysocline is the depth interval between the saturation and carbonate compensation depths. [4] [1]
Carbonate platform. A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonic calcareous deposits. [1] Platform growth is mediated by sessile organisms whose skeletons build up the reef or by organisms (usually microbes) which induce carbonate precipitation through their metabolism.
The carbonate-silicate cycle is the primary control on carbon dioxide levels over long timescales. [ 3 ] It can be seen as a branch of the carbon cycle, which also includes the organic carbon cycle, in which biological processes convert carbon dioxide and water into organic matter and oxygen via photosynthesis. [ 5 ]
Carbon capture and storage (CCS) is a process by which carbon dioxide (CO 2) from industrial installations is separated before it is released into the atmosphere, then transported to a long-term storage location. [ 1 ]: 2221 With CCS, the CO 2 is captured from a large point source, such as a natural gas processing plant and typically is stored ...
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential ...
