There are many coastal processes, each of which helps form different coastal landforms.



The breaking waves hurl sand and pebbles onto the cliff, which then break off pieces of rock - causing undercutting trish to mpover .


Soluble rocks are dissolved into the sea. This is most effective on chalk and other limestone rocks which are then carried away in solution.


The rocks and other particles carried by the waves are reduced in size as they collide with the rockface and other rocks.

Hydraulic ActionEdit

This is the sheer power of the waves hitting the cliffs.


This happens because the sea loses energy. It drops the heavier load first. Deposition is more likely to happen when:

  • waves enter a shallow or protected area
  • there is no/little wind



Large boulders roll along the seabed in constant contact with it.


This is where smaller pebbles or sand bounce along the seabed.


Fine sediment are suspeneded in the water by turbulence. They do not touch the seabed.


Dissolved particles are carried invisibly in the water.
