The age of the Earth is around 4.6 billion years old

Answer:

The earth is about 4.6 billion years old.

Explanation:

"The processes of plate tectonics mean that the Earth is constantly recycling its rock, breaking it down into magma in the interior before pumping it back up to the surface once more. ... Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old."
