the correct answer you are looking for would be letter B. formation of geological layers
hope this helps :)
The correct answer is option B, that is, the formation of geological layers.
The flow of heat from the interior of the Earth to the surface is predicted in term of terawatts and it comes from two prime sources and it comes in approximately equal concentrations, that is, the radiogenic heat generated by the radioactive decay of isotopes in the crust and the mantle, and the accretion heat or the primordial heat left over from the creation of the Earth.
Apart from this, the gravitational compression refers to a procedure in which gravity functioning on the mass of an object, compresses it, minimizing its size, and enhances the density of the object. At the center of a plant, the gravitational compression generates heat by the mechanism of Kelvin-Helmholtz.
The generation of the geological layers refers to the fundamental unit of lithostratigraphy. It is a formation comprising of some amount of rock strata, which exhibits a comparable facies, lithology, or other identical characteristics. However, the process does not directly contribute to Earth's high internal temperatures.
