Final answer:
The correct order of how the inner planets were formed is Moon, Mercury, Venus, Earth.
Step-by-step explanation:
The correct order of how the inner planets were formed is as follows:
- Moon was formed by the collision of Earth with a Mars-sized object.
- Mercury was formed through a process of giant impacts which stripped it of part of its mantle and crust.
- Venus had its rotation reversed due to a giant impact.
- Earth had part of its material stripped off through a giant impact, which eventually formed the Moon.
So, the correct order is Moon, Mercury, Venus, Earth.
