Why the earth interior is very hot give the reasons behind it?
The main reasons the Earth's interior is hot are: The Earths crust is a good insulator, so interior heat is lost only slowly. The Earth was very hot when it formed (when the pieces of stuff came together to form the Earth). Much of this heat is still there today. The interior material is molten (liquid). They move around creating friction between these elements. Friction causes heat, so this motion of stuff in the liquid center results in heat from friction. When radioactive materials decay...
