Product Description
The geothermal gradient is the rate at which the Earth’s temperature increases with depth, indicating outward heat flows from a hot interior. Away from tectonic plate boundaries, it is 25-30°C per km of depth in most of the world. Strictly speaking, geo-thermal necessarily refers to the Earth but the concept may be applied to other planets. The Earth’s internal heat comes from a combination of residual heat from planetary accretion (about 20%) and heat produced thr… More >>
