Earth's internal heat
WebInternal heat is the heat source from the interior of celestial objects, such as stars, brown dwarfs, planets, moons, dwarf planets, and (in the early history of the Solar System) … WebBest estimates for origins of heat flow from Earth give 80-50% radioactive origin, 20-50% primordial, witha a likely radioactive dominance approx. 80 : 20%. Note: If losing primordial heat the Earth must be cooling slowly. Estimates range from 5 to 10 K per 100 Ma -> 230 to 460 K over life span of Earth.

WebThe Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron … 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 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.

Most of Earth’s internal heat is left over from when our planet formed, about 4.5 billion years ago. Earth and the other planets in the solar system first began to take shape as countless smaller bodies collided and clumped together. The energy of those violent collisions transformed into heat energy.
