The surface of the Moon may be described as
A) eroded basalt held together by subsurface ice (permafrost).
B) regolith (pulverized rock) in and near craters and hard bedrock everywhere else.
C) hard bedrock almost everywhere because there is very little erosion on the Moon.
D) regolith (pulverized rock).

Question

Quizplus · Accepted Answer

The surface of the Moon is covered by a layer of regolith, which is essentially pulverized rock created by the constant bombardment of meteoroids over billions of years. This layer varies in thickness but is present across much of the Moon's surface, making option D correct. The Moon lacks an atmosphere that could facilitate weathering and erosion like on Earth, so there isn't significant erosion of basalt or the presence of permafrost, and while there is bedrock, it's not exposed everywhere as the regolith covers it.
