WitrynaThe intense compression of material deep inside the Earth increased internal heat even further. Once temperatures were high enough, the element iron began to melt and sink toward the center, as less dense material rose towards the surface. The friction of the iron moving down through the other material generated even more heat. WitrynaThe accretion of a homogeneous mass that comprises the earth and the loss of …
