B)lava flows welling up in the mare.
C)volcanic vents in the rugged highlands.
D)the rain of micrometeorites chewing up the regolith.
E)rain from cometary debris melting as it enters the Moon's atmosphere.

Question

Quizplus · Accepted Answer

The rain of micrometeorites is the chief erosive agent on the Moon, as these tiny particles constantly impact the Moon's surface and slowly wear down the regolith. While the other options can contribute to erosion in their own ways, they are not as significant as the constant bombardment of micrometeorites. The rain of micrometeorites chewing up the regolith is the chief erosive agent on the Moon as it constantly bombards the surface, breaking down and grinding away at the regolith. The other options are not currently active erosive agents on the Moon.
