Processes called erosion, mass movement and weathering break down and remove material from the coast. Many factors affect the rates of coastal erosion and the landforms created.
Another way material can be moved on the coastline is through mass movementA large-scale downward movement of rocks and material. . Mass movement is the downhill movement of sediment that moves because of gravity.
Rockfall
Bits of rock fall off the cliff face, usually due to freeze-thaw weathering.
Landslide
Large blocks of rock become detached and slide downhill.
