how is heat produced within the earth
In other words, Earth has been losing heat since it formed, billions of years ago. But itâs producing almost as much heat as itâs losing. The process by which Earth makes heat is called radioactive decay. It involves the disintegration of natural radioactive elements inside Earth â like uranium, for example.Uranium is a special kind of element because when it decays, heat is produced. Itâs this heat that keeps Earth from cooling off completely.ut itâs producing almost as much heat as itâs losing. The process by which Earth makes heat is called radioactive decay.
