The moon's main source of erosion is micrometeorites.

Explanation:

Erosion on earth occurs mainly because of the action of wind, water and rain. On the moon, however, there is not atmosphere, so no weather.

Instead, tiny dust particles impact the surface of the moon from space. These particles hit the Earth as well, but burn up in the upper atmosphere. On the moon there is no atmosphere, so they hit the surface.

The lack of weather on the moon is the reason erosion is so slow, and we can see features that are millions and even billions of years old.
