Geology Exam #4 Questions With Answers Mass wasting the downslope movement of rock, regolith, snow, or ice due to the pull of gravity Landslide a sudden movement of rock and debris down a nonvertical slope Soil creep the very slow, gradual movement of regolith downslope → driven by expansion and contraction cycles (freeze-thaw and wetting-drying) Failure surface A weak surface that forms the base of a landslide. Slump A semi-coherent volume of regolith that slipped do...
