Geography- Coasts.

Particles carried by the waves crash against each other and are broken up into smaller particles.

Particles carried by the waves crash against the cliffs, eroding the cliffs.

• Salt in the seawater slowly dissolves the cliffs.

• The material produced is carried away by the process of solution.

• 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.

• 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.

Processes of coastal erosion include attrition, corrasion, corrosion, hydraulic action and sub-aerial processes.

Coastal deposition occurs when the waves loose energy.
