If Earth's gravity were much less powerful, our atmosphere would be similar to the moon's.

Explanation:

The gravity on the Moon is 16.66% of what is on Earth. This kind of gravity,  in astronomical language, is called 'microgravity'. Much less gravitational power on Earth would have turned it into microgravity, which would apparently have been unable to hold down most of the gases that constitute the atmosphere on Earth. For the gravity on the Moon is very less, it only has a few gases like sodium and potassium. Most of he gases that are present on the Moon are not naturally found on Earth.
