Answer:
1) Rain mixes with soil. Soil and paper debris are combined. Loosely connected rocks bind together.
2) Creep
3)Surface material breaks down into smaller pieces. Very dense particles settle faster than low-density particles. Large particles are carried away to a new location by ice and glaciers.
4)the wind
5) weathering or erosional debris cover on slopes, which is usually liable to mass movement; the character and structure of rocks.
6)soil mixed with water sliding off a cliff
7) Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions.
8) Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up the rock.
9) It allows sediments to fall out of a medium.
