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. Much of the organic carbon retained in the soil of agricultural areas has been depleted due to ...
Carbon sequestration is the process of storing carbon in a carbon pool. [2]: 2248 It plays a crucial role in limiting climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic (also called biosequestration) and geologic. [3] Biologic carbon sequestration is a naturally ...
A biogeochemical cycle, or more generally a cycle of matter, [1] is the movement and transformation of chemical elements and compounds between living organisms, the atmosphere, and the Earth's crust. Major biogeochemical cycles include the carbon cycle, the nitrogen cycle and the water cycle. In each cycle, the chemical element or molecule is ...
It is usually transported via pipelines and then either used to extract oil or stored in dedicated geologic formations. Carbon capture and storage (CCS) is a process in which carbon dioxide (CO 2) from industrial installations is separated before it mixes with the atmosphere, then transported to a long-term storage location. [ 1 ]: 2221 In CCS ...
Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It should not be confused with green chemistry, which seeks to reduce potential pollution at its source. It can be defined as the study of the sources, reactions, transport, effects, and fates of chemical species in the air ...
The oceanic carbon cycle (or marine carbon cycle) is composed of processes that exchange carbon between various pools within the ocean as well as between the atmosphere, Earth interior, and the seafloor. The carbon cycle is a result of many interacting forces across multiple time and space scales that circulates carbon around the planet ...
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]
v. t. e. The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. [1] In other words, it is a biologically mediated process which results in the sequestering of carbon in the ...
