WebDefinition. A geothermal gradient is the increase in temperature with increasing depth beneath the Earth’s surface. This gradient is due to outward heat flow from a hot interior.

"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… " - Geotherm definition geology
