What is the signature of rapid, episodic mass movement? - ANS-hummocky topography What causes soil creep? - ANS-barely predictable, non-accelerating downslope movement. Caused by the expansion and contraction of soil as a result of heating and cooling, freezing thawing or wetting and drying. When soil expand it does so perpendicular to the surface of the slope, and when it contracts, it does so under a dominantly gravitational component (convex) How is sediment transport by flows diffe...
