Mass movement

Another way material can be moved on the coastline is through mass movement. Mass movement is the downhill movement of sediment that moves because of gravity.


Rocks fall off the cliff face forming scree at the bottom.

Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.


Rocks detach off the slide plane and slide down to the bottom.

Large blocks of rock become detached and slide downhill.
