"WebHot stuff on the surface of the Earth cools fast because air can carry away the heat pretty easily by convection. This heat is eventually radiated back to space. The outer core, on the other hand, touches the hot mantle. Due to the relatively small temperature difference, there's not much heat transfer to the mantle. " - How hot is the earth's mantle
