Sources Of Heat In The Mantle

Earths internal heat budget - Wikipedia. Earth's internal heat budget is fundamental to the thermal history of the Earth.The flow of heat from Earth's interior to the surface is estimated at 472 terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat …

Mantle Convection - an overview ScienceDirect Topics

Mantle convection and plate tectonics provide a general framework for understanding tectonophysics. Transport of heat from the interior of the earth drives solid-state convection. Plate tectonics is a direct consequence of this convection. The relative velocity between plates causes crustal deformation at the boundaries between plates.

The uranium and thorium amounts in the Earth crust and mantle are estimated respectively to 50,000 and 160,000 billion tons. According to this estimate, uranium alone would release the electrical energy produced by 4620 nuclear power plants of 1 Gigawatt. The decay heat has somewhat decreased since the Earth formation, 4 billions years ago.
