Answer:

1. Mars-sized planetesimal collides with Earth
2. The molten material is ejected from Earth
3. Material accretes to form the Moon
4. The moon begins rotating and revolving around Earth

Explanation:

This is how it is believed that the moon was formed. During the formation of the solar system, rocks, ice, and gases came together in a collision, due to their own gravity, forming the rock and gas planets that we see today. During this bombardment, some material became ejected the earth to form the moon. The moon revolves around the earth because it is within the pull of the earths gravitational field.
