The radioactive isotopes uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in Earth’s mantle are the primary source.

WebThe Earth’s internal heat has three main sources. Two of these sources are related to the formation of the Earth and its internal layering (i.e. the core, mantle, and crust), the heat from which has been slowly dissipating since that time. The third source of heat is attributed to ongoing radioactive decay, which adds to the global heat budget.
