Geothermal gradient is the rate of temperature change with respect to increasing depth in Earth's interior. As a general rule, the crust temperature rises 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. However, in some cases the tem… WebJun 1, 2005 · Whereas up to 4000 ppm wt. of H 2 O could be dissolved in the upper mantle at pressures corresponding to 410 km depth, such a value is less than the 1.5–2.5 wt.% solubility stored in the hydrous phases of the transition zone.
