Answer to Question 1

First, resisting forces are reduced in general. This is particularly true where slumps are involved. The
portion of a slump where the landslide angles upward toward the surface actually contributes forces
that counter the tendency of the rest of the mass to move down slope. Unloading this sensitive area
decreases resistance to movement. Second, excavating the downslope end of a landslide changes the
slope angle locally, thus removing lateral support and encouraging slumping or block glides, the later
typically occurring where bedding planes are exposed.



Answer to Question 2

Burrowing animals can move soil where more animal-moved soil ends up moving downslope than
upslope; the net result is downslope transport. Trees are an important catalyst for soil creep. Every
time a tree blows over and its root wad tips up, soil is moved, usually downslope
