mass movement

Question 1

explain the process of slumping

Answer 1

excess rainfall at the clifftop saturates the soil

this collapses downhill in a curved motion

this curved section the soil follows is called a slip plane

Question 2

explain the process of rockfall

Answer 2

rocks are weathered by freeze-thaw which weakens them and causes them to break off

this rock fragment then falls down the slope/cliff

the rock fragments then collect at the base of the cliff as scree

Question 3

explain the process of sliding

Answer 3

excess rainfall at the clifftop saturates the soil

this means it becomes unstable and top-heavy

the mudslides downhill (due to gravity) forming a lobe at the base of the cliff)
