What is Attrition?
Particles carried by the waves crash against each other and are broken up into smaller particles.
What is Abrasion (Corrasion)?
Particles carried by the waves crash against the cliffs, eroding the cliffs.
What is Corrosion?
- Salt in the seawater slowly dissolves the cliffs.
- The material produced is carried away by the process of solution.
What is Hydraulic Action?
- The water traps air in cracks and caves in the rock.
- This air is compressed by the incoming waves placing great pressure on the rocks, causing them to crack eventually.
What are the Sub - Aerial processes?
- The impact of rainwater, wind and frost on the cliffs.
- Rainwater can cause surface erosion.
- Frost shattering can occur in colder climates.
- Rainwater can also increase the chances of mass movement occurring.
- Wind erosion can aid in the erosion of the cliffs.
Name the coastal processes.
Processes of coastal erosion include attrition, corrasion, corrosion, hydraulic action and sub-aerial processes.
When does coastal deposition occur?
Coastal deposition occurs when the waves loose energy.
Name a process of coastal transportation.
