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

ErosionEdit

CorrasionEdit

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

SolutionEdit

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

AttritionEdit

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.

DepositionEdit

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

TransportationEdit

TractionEdit

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

SaltationEdit

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

SuspensionEdit

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

SolutionEdit

Dissolved particles are carried invisibly in the water.
