How do you geo guys factor in the difference between Mars and Earth gravity? I would imagine that it would make big differences in the way erosion works, for instance.

The gravity parameter "g" does show up, for example, in several flow equations. As for whether it makes a "big difference" -- that depends. Certain properties like runout distance, vorticity, turbulence, and hence, erosive capability, may scale linearly or exponentially (either directly or inversely) with gravity depending on the circumstances.
