How many years ago earth was originated ? (a) 4000 million (b) 5000 million (c) 2000 million (d) 3000 million

Answer 1

This is a tricky question to ask How many years ago earth was originated.

In a process known as runaway accretion, successively larger fragments of dust and debris clumped together to form planets.

Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) and was largely completed within 10–20 million years.
