Coastal Processes

Attrition
A type of erosion where rocks smash against each other making them smaller and more rounded.
1 of 13
Abrasion
Erosion of the landscape caused by friction. Abrasion occurs when rivers or waves are carrying sand or pebbles. The water uses these materials to do the work of erosion.
2 of 13
Hydraulic Action
Erosion caused when water and air are forced into gaps in rock or soil.
3 of 13
Corrosion
The wearing away of the landscape by chemical processes such as solution.
4 of 13
Longshore Drift
A process by which beach material is moved along the coast.
5 of 13
Deposition
The laying down of material in the landscape. Deposition occurs when the force that was carrying the sediment is reduced.
6 of 13
Swash
The flow of water up the beach as a wave breaks on the shore.
7 of 13
Backwash
The flow of water back into the sea after a wave has broken on the beach.
8 of 13
Traction
The process of transport which describes the movement of larger pebbles and cobbles as they roll along the bed of the river.
9 of 13
Transport
The movement of material throught the landscape.
10 of 13
Erosion
The wearing away of the landscape.
11 of 13
Fetch
The distance a wave travels over open sea.
12 of 13
Retreat
The gradual backward movement of a landscape due to the process of erosion. The coastline retreats due to the erosion of a cliff and a waterfall retreats towards the source of river as it is eroded.
