Description
Protoplanetary Earth, illustration. The Earth formed from small rocky bodies (planetesimals) that accreted (due to gravitational attraction) in the protoplanetary disc of the early Solar System. As the planetesimals impacted the protoplanet, they turned the surface molten and triggered volcanic eruptions. This is the process by which the Earth and the other inner Solar System planets formed around 4.6 billion years ago.
