Well, I don't really know, but the Wikipedia entry says: "Estimates of the total heat flow from Earth’s interior to surface span a range of 43 to 49 terawatts (TW) (a terawatt is watts ). [9] One recent estimate is 47 TW, [1] equivalent to an average heat flux of 91.6 mW/m2, and is based on more than 38,000 measurements.
Jun 17, 2024 · onyx backlitEarth'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 47±2 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 left over from the formation of Earth. onyx backpackWebDec 15, 2024 · Earth generates heat.
