Types of erosion
Corrasion-Caused by large waves hurling beach material against a cliff
Attrition-When waves cause rocks and boulders on the beach to bump into each other and to break up into small particles
Corosion (solution-When salts and other acids in the sea slowly dissolve a cliff
Hydraulic pressure-When the force of waves compressing air cracks in a cliff
- Weather weakens the top of the cliff.
- The sea attacks the base of the cliff forming a wave-cut notch.
- The notch increases in size causing the cliff to collapse.
- The backwash carries the rubble towards the sea forming a wave-cut platform.
- The process repeats and the cliff continues to retreat.
Headlands are formed when the sea attacks a section of coast with alternating bands of hard and soft rock.
