Alternative answers:
Waves approaching the coast at an angle result in the gradual zig-zag movement of beach materials along the coast.
Once rocks are detached from the cliff, waves can move them along the coastline for quite long distances, this process is known as longshore drift. Generally speaking, the smaller the material, the further it is likely to be moved by waves as it is lighter. Eventually, the waves are unable to move so much materials and the materials will be deposited to create new land forms.
