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

Erosion[edit | edit source]

Corrasion[edit | edit source]

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

Solution[edit | edit source]

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

Attrition[edit | edit source]

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

Hydraulic Action[edit | edit source]

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

Deposition[edit | edit source]

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

Transportation[edit | edit source]

Traction[edit | edit source]

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

Saltation[edit | edit source]

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

Suspension[edit | edit source]

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

Solution[edit | edit source]

Dissolved particles are carried invisibly in the water.
