8. How are cliffs and wave-cut platforms formed?

9. Wave-cut platform Task1
The waves attack the base of the cliff through the processes of abrasion, corrosion, hydraulic action and attrition.
Over time the cliff will be undercut and a wave-cut notch is formed.
Eventually the cliff becomes unstable and collapses. Further cliff retreat will form a wave-cut platform.
