- Erosion-Coastal
- Hydraulic Action
- Hydraulic action is when a wave breaks against a cliff face. This forces water into the cracks and weaknesses, compressing the air.
- Hydraulic action helps to create many coastal landforms such as caves, arches,stack and stumps
- It is a marine process
- Hydraulic action uses destructive waves to erode the coastline
- Attrition
- Attrition is the smoothing and reducing of angular rock fragments into pebbles shingle and eventually sand particles
- Attrition causes rocks to become smaller and so erodes the coastline dramatically
- It is a marine process
- Abrasion
- Abrasion is the launching of rock fragments and pebbles against cliffs by waves.
- It causes weaknesses within the cliffs
- It contributes t the formation of coastal landforms such as caves, arches, wave cut notches and wave cut platforms
- Solution
- Solution is when rock such as chalk and limestone are dissolved when it comes in contact with water
- It is a type of chemical erosion
- Hydraulic Action
- Attrition causes rocks to become smaller and so erodes the coastline dramatically
