Continental AG, commonly known as Continental and colloquially as Conti, [3] is a German multinational automotive parts manufacturing company. Headquartered in Hanover, Lower Saxony , it is the world's third- largest automotive supplier and the fourth-largest tire manufacturer.
Carbon can be produced in stars at least as massive as the Sun by fusion of three helium-4 nuclei: 4 He + 4 He + 4 He --> 12 C. This is the triple alpha process.In stars as massive as the Sun, carbon-12 is also converted to carbon-13 and then onto nitrogen-14 by fusion with protons.
The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the ... Continental shelves and the open ocean typically absorb CO 2 from ...
Combined with the investment from Continental Resources, Summit Carbon Solutions now has over $600 million of equity commitment for its proposed carbon capture and storage project in the Williston ...
Carbon principally enters the mantle in the form of carbonate-rich sediments on tectonic plates of ocean crust, which pull the carbon into the mantle upon undergoing subduction. Not much is known about carbon circulation in the mantle, especially in the deep Earth, but many studies have attempted to augment our understanding of the element's ...
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.

The strontium isotopic composition (87 Sr/ 86 Sr) of seawater represents a mix of strontium derived from continental weathering which is rich in 87 Sr and from mantle sources e.g. mid-ocean ridges, which are relatively depleted in 87 Sr. 87 Sr/ 86 Sr ratios above 0.7075 indicate continental weathering is the main source of 87 Sr, whilst ratios ...
A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet. [6] Additionally, the levels of carbon dioxide and other greenhouse gases (such as water vapor and methane) are high, and sea surface temperatures (SSTs) range from 28 °C (82.4 °F) in the tropics to 0 °C (32 °F) in the polar regions.
