The structure of Earth exchanged because of collisions of a planet with other objects

The international team of researchers presented work which explained why the structure of Earth exchanged. They assumed that process was started because of blows of asteroids. The group of researchers of University Clermont-Overni together with colleagues from Bayroytsky universities found out proofs of that the structure of Earth changed because of a conflict erosion. In the work published in the Science magazine, the group describes research of amount of samarium and neodymium in meteorites and that it showed them about processes which led to present structure of Earth. The previous researches showed...
