1. It is produced by the radioactive decay of isotopes in the mantle and crust. 2. This refers to the heat left over from the formation of the earth. 3. A heat transfer of fluid in the earth's interior results to the movement of rocky mantle up to the surface?
Radiogenic heat is the heat generated by the decay of radioactive isotopes of the elements. Radiogenic heat was investigated as the source of heat flux over and above the primordial heat in the Earth.
2.Residual heat
is the gravitational energy left over from the formation of the Earth, by theMantle convection is the process by which the excess heat in the Earth's deep interior is transferred to its surface through the fluid-like motions of the rocks in the mantle. “falling together” and compression of cosmic debris (much like a bicycle pump that heats up due to the compression of air inside it). All radioactive decay processes release heat as a by-product.
