How old is the Earth?
|
It is difficult to tell, as the Earth's surface is constantly changing and reforming. The Earth formed at the same time as the rest of the planets in the Solar System. As far as we can tell, the oldest rocks on the Earth's surface formed about 4,500 million years ago. | | A diagram detailing Earth's history |
