Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or … 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… christian ptsd treatmentWitrynaThe processes affecting magma composition include partial melting, magmatic differentiation, assimilation, and collision.
