52. Is the Moon's surface similar to a desert? (A K2S Question)

From The Space Library

There is dust and sand, but it's far, far drier than any desert on Earth. Because of the different environments, dust particles on an individual level will have different mechanical properties than dust and sand on Earth. Because of the lower gravity the dust is able to have much steeper slopes then on Earth which is part of why the pictures of the footprints on the Moon show such sharp edges.
