Explanation:
The formation and evolution of planet Earth is a scientific detective story that has taken astronomers and planetary scientists a lot of research to figure out. Understanding our world's formation process not only gives new insight into its structure and formation, but it also opens new windows of insight into the creation of planets around other stars
As time went by, planetesimals collided with other bodies and grew larger. As they did, the energy of each collision was tremendous. By the time they reached a hundred kilometers or so in size, planetesimal collisions were energetic enough to melt and vaporize much of the material involved. The rocks, iron, and other metals in these colliding worlds sorted themselves into layers. The dense iron settled in the center and the lighter rock separated into a mantle around the iron, in a miniature of Earth and the other inner planets today
The oldest surviving rocks on Earth were laid down some five hundred million years after the planet first formed. It and other planets suffered through what's called the "late heavy bombardment" of the last stray planetesimals around four billion years ago). The ancient rocks have been dated by the uranium-lead method and appear to be about 4.03 billion years old. Their mineral content and embedded gases show that there were volcanoes, continents, mountain ranges, oceans, and crustal plates on Earth in those days
