Answer to Question 1

Steeper slope angles, and structural factors like bedding plane orientations, make a slope susceptible to mass wasting. Human alteration of slopes can affect susceptibility, as well. Vegetation can help anchor materials. Water contributes to weathering, adds weight to porous materials on a slope, decreases the strength of unconsolidated sediments, and can increase the slope angle. Rainstorms or earthquakes can trigger movement.

Answer to Question 2

In slides, a cohesive or semicohesive unit of Earth materialslips downslope in continuous contact with the land surface. Flows are masses of water-saturatedunconsolidated sediments that move downslope becauseof the pull of gravity.Compared with slides, which tend to move as cohesive units,flows involve considerable churning and mixing of the materialsas they move.
