Question

which factors can lead to a mass movement? check all that apply
steep slopes
removal of vegetation
deposition
animal activity
earthquakes
undercutting of a slope

Explanation:

• Steep slopes: Steeper slopes have a greater gravitational pull component acting parallel to the slope, increasing the likelihood of mass movement.
• Removal of vegetation: Vegetation roots help hold soil in place. Without them, soil is more prone to sliding.
• Animal activity: Burrowing animals can loosen soil and rock, potentially triggering mass movement.
• Earthquakes: Seismic activity can shake loose soil and rock, causing mass movement.
• Undercutting of a slope: Removing material from the base of a slope (undercutting) reduces support, making the slope more unstable.
• Deposition: Deposition is the process of sediment being laid down. It does not directly cause mass movement.

Answer:

steep slopes, removal of vegetation, animal activity, earthquakes, undercutting of a slope
