The four types of mass movements are: Rock Falls-a rock fall happens when loose rocks fall down a steep slope Landslides-the sudden movement of rocks and soil down a slope Mudflows-the flow of a mass of mud or rock and soil mixed with a large amount of water Creep-the slow downhill movement of weathered rock material
A landslide.
i would assume gravity? a slope is downhill, so if rocks are loose they will naturally travel downwards.
gravity
Usually by erosion, although weathered rocks can split off to trigger a slide. A landslide is the downhill motion of loose rock and soil, sometimes entire layers of a mountainside.

gravity
The valley have steep sides because soil and loose rocks are washed downhill after a heavy rainfall. The soil and rock also create a load in the river.
gravity
It can be done by dinamites blast.
