A questions arose in class today about how destructive process would effect the moon. Since there is no liquid, no atmoshpere, and low gravity, how would erosion, chemical weathering, physical weathering, and mass wasting effect the moon. I am trying to figure out which one would have more of an effect and which one would have the least effect.

Craig -

There is little weathering on the moon for the reasons you cited. The surface on the moon remains largely unchanged for millions of years. Meteors may strike the surface... though there seems to be fewer of them now than in the far distant past. There is also some change due to the heating and cooling from the sun... but again very little.

Hope these thoughts help
