1st Year- Mass Movement - Factors Affecting Mass Movement

Question 1

Gradient/ slope

Answer 1

Steeper slopes have more mass movement

Question 2

Water content

Answer 2

Heavy rainfall makes regolith heavier and able to slide more easily increasing the risk of mass movement

Question 3

Vegetation

Answer 3

Plant’s roots hold soil grains together preventing mass movement. Once plants are removed from a slope, soil moves easily down hill

Question 4

Human activity’s

Answer 4

Increase the risk of mass movement by undercutting slopes, deforestation and grazing to many animals
