The sources of heat combined with the earth s crust keeping much of this heat from escaping is why the earth s interior is hot.
The earth interior is very hot why. The earth was formed by the process of accretion. 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 deepest layer is a solid iron ball about 1 500.
In the process of cooling after breaking away from the sun the interior of the earth cooled at a. A lot of earth s heat is leftover from when our planet formed four and a half billion years ago. 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.
The interior of the earth generates heat by radioactive decay. It is thank to the continous nuclear fission of elements in the earth s interior that replaces the heat the earth loses keeping it nice and hot. Earth was hot when it formed.
Through time an atom of these elements will kick out or lose protons or neutrons. The melting temperature of iron under deep earth. The weight of the overlying materials exerts great pressure on the core resulting into high.
Other radioactive elements are also present but these three provide the bulk of the heat at present. The interior of earth is very hot the temperature of the core reaches more than 5 000 degrees celsius for two main reasons. The 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 interior of earth is hot because of a process called radioactive decay. The most important contributors are the decay of uranium 238 to lead206. The decay of thorium 232 to lead 208 and the decay of potassium 40 to calcium 40 and argon 40.
