Early Stage Earth

When the Earth was formed 4.6 billion years ago, it would never have been called the Blue Planet. | But there were violent collisions, explosions, and eruptions. | There were no oceans, there was no oxygen in the atmosphere, and no life. | This process of separation created the layers of the Earth as we know them. | In fact, the Earth in its earliest stage was molten, which allowed elements to separate into layers within the Earth: gravity pulled denser elements toward the Earth's centre, while less dense materials accumulated near the surface.
