What atmospheric function is absent on the Moon that causes space debris to strike unimpeded?

Answer

Atmospheric friction/drag.

On Earth, atmospheric friction causes small space debris to burn up harmlessly; on the Moon, the lack of atmospheric drag means rocks and particles strike the surface unimpeded at high speeds.
