Water makes regolith causing it to move downslope faster. Water can also act as a lubricant which makes the movement of the regoluth easier. |
|
|
Human activity |
Building roads or quarrying in upland areas can make the land unstable and cause movement. |
|
|
Vegetation |
The roots of planys and trees keep the soil stable and help to prevent mass movement. |
|
|
Animals |
Burrowing animals or overgraIng can make the slope unstable and cause mass movement. |
|
|
Soil creep |
Soil creep us the movement of soil down a slope under the influence of gravity. |
|
|
Bog bursts |
