What causes the erosion of rocks on the moon’s surface?

Meteors

Explanation:

The moon does not have an atmosphere. Thus, it does not have weather patterns like on Earth. No winds blow on it unlike on Earth where wind and water cause soil erosion.

On moon, high speed space dust and rocks of all sizes hit and cause the erosion of rocks. In the absence of atmosphere, these space rocks are not burnt away but hit the surface creating craters.
