Question 11 • (OC27) Earth/Space Sci-2001310-S2-Nelson

When astronauts step from landing ships onto the surface of the Moon, which statement best describes what happens?

Answer
A
Their boots sink slightly into the surface because it is muddy due to rainfall.
B
Their boots make impressions on the surface because it is powdery and there is no rainfall.
C
Their boots slip constantly on the surface because it is covered with sand and there is no gravity.
D
Their boots remain firm on the surface because it is very rocky and there is a lot of gravity.

Explanation

The Moon has no rain or liquid water to make its surface muddy, and its surface is covered in fine, powdery dust called lunar soil. Astronauts’ boots can press into this material and leave impressions. Choice B correctly describes the powdery surface and lack of rainfall.
