Earths internal heat budget - Wikipedia

Earths internal heat budget - Wikipedia

Earth's internal heat budget is fundamental to the thermal history of the Earth.The flow of heat from Earth's interior to the surface is estimated at 47 2 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of Earth.

Geothermal gradient - Wikipedia

Geothermal gradient - Wikipedia

Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth's interior. As a general rule, the crust temperature is rising with depth due to the heat flow from the much hotter mantle; away from tectonic plate boundaries, temperature rises in about 25–30 C/km (72–87 F/mi) of depth near the surface in most of the world.

Io (moon) - Wikipedia

Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and third-largest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth’s moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water (by atomic ratio) of any known astronomical object in the Solar System.

Mar 01, 2022 Modelling of the Nd and Sr isotope data shows that the mid-Eocene to early Oligocene K-rich magmatism of the SAB is the result of low degree partial melting of a metasomatized mantle source (SCLM), mixing with an upwelling asthenospheric mantle. Mid-Eocene-early Oligocene K-rich magmatism in the SAB and NW Iran coincided with a …

Global Carbon Cycle - an overview | ScienceDirect Topics

R.A. Houghton, in Treatise on Geochemistry, 2003 8.10.1 Introduction. The global carbon cycle refers to the exchanges of carbon within and between four major reservoirs: the atmosphere, the oceans, land, and fossil fuels. Carbon may be transferred from one reservoir to another in seconds (e.g., the fixation of atmospheric CO 2 into sugar through photosynthesis) or over …

The assessment of the literature since AR5 made in Section 3.3.1 shows that the contribution from Greenland to SLR over 2012–2016 (0.68 (0.64 – 0.72) mm yr –1) was similar to the contribution over 2002–2011 (0.73 (0.67 – 0.79) mm yr –1) and extremely likely greater than over 1992–2001 (0.02 (0.21 – 0.25) mm yr –1).
