Marine life. 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 ...
This is a list of sovereign states and territories by carbon dioxide emissions[ n 1 ] due to certain forms of human activity, based on the EDGAR database created by European Commission and Netherlands Environmental Assessment Agency. The following table lists the 1970, 1990, 2005, 2017 and 2022 annual CO 2 emissions estimates (in kilotons of CO ...
Carbon cycle. The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component of biological compounds as well as a major component ...
3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use. The complete nomenclature for a battery specifies ...
The current global average concentration of carbon dioxide (CO 2) in the atmosphere is 421 ppm (0.04%) as of May 2022. [ 1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. [ 2][ 1][ 3] The increase is due to human activity.
Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. [ a][ 2] It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold ...
This is a list of auto parts, which are manufactured components of automobiles. This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive. Many (not all) of these parts are also used on other motor vehicles such as trucks and buses.
A carbon–carbon bondis a covalent bondbetween two carbonatoms.[1] The most common form is the single bond: a bond composed of two electrons, one from each of the two atoms. The carbon–carbon single bond is a sigma bondand is formed between one hybridized orbital from each of the carbon atoms. In ethane, the orbitals are sp3 ...
