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. WebEarth's core is losing energy to the universe. Just very very slowly. Also radioactive elements in the mantle and the core heat up Earth's interior. Also the friction of infalling material to the core adds heat to Earth's core. Also all those layers of rock prevent Earth from losing heat. Share Cite Improve this answer Follow
WebThe heat of Earth’s interior comes from a variety of sources. These include the heat contained in the objects that accreted to form Earth, and the heat produced when they collided. As Earth grew larger, the increased … 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.
