Factors that affect Mass Movement
Burrowing animals can loosen the soil making it unstable.
The roots of plant and tress bind the soil together. This helps prevent mass movement.
People sometimes dig into slopes in upland areas during construction. This makes the slope steeper allowing the regolith to move faster.
Water makes regolith heavier. Heavier regolith moves downslope faster. Water can also act as a lubricant.
Gradient refers to the steepness of the slope.
The different types of mass movement
Controlling Mass movement
Vegetation such as trees and vines can be planted into slopes to stabilise them
Steps can be built into a mountainside to trap moving material.
Restricted overgrazing keeps vegetation cover and soil creep together.
Controlled explosions in mountainous areas can be used to trigger small avalanches , making large avalanches less likely
