How has the earth changed since it was formed?

Question asked by: knowitall

The earth has changed massively since it was formed. Initially it was a ball of rock that got hit and changed by loads of impacts and meteor impacts.

It was a boiling, burning pile of rubble effectively.

Over time it developed an atmosphere that changed in time as liquid water gathered on the surface of the earth and created an atmosphere with clouds of water and levels of certain gases that protected the planet below and made it the temperature that it is, which is obviously fit for life as we can tell by looking around us.
