The notch increases in size causing the cliff to collapse. Weather weakens the top of the cliff. The backwash carries the rubble towards the sea forming a wave-cut platform. The sea attacks the base of the cliff forming a wave-cut notch. The process repeats and the cliff continues to retreat. Correct order 1. 2. 3. 4. 5.
