The temperature within the interior of the earth is described by the geothermal gradient, which is the rate of temperature change with depth. The geothermal gradient is established by the balance between heating through radioactive decay in the Earth's interior and heat loss from the surface of the earth. The geothermal gradient averages about 25 °C/km in the Earth's upper crust, but this varies widely by region, from a low of 5–10 °C/km within oceanic trenches and subduction zone… WebWhen magma cools, it solidifies to form rock which is called "igneous rock". That is deceptively simple, since the solidification process can be very complex. There is a considerable range of melting temperatures for different compositions of magma.
