Wave cut platform

• Weaknesses such as joints and crack are eroded and undercut between the high and low tide marks, forming a wave cut notch.
• The rock above overhangs over the notch, and as erosion continues the notch enlarges until the unsupported overhang eventually falls as it is too heavy.
• The new cliff face is eroded and the cliff retreats inland overtime, leaving a gently sloping rocky surface called a wave cut platform, which extends out to sea away from the cliff.
• The wave cut platform is eroded by rock materials, with rock pools and pot holes forming which are evident at low tide.
• Wave cut platform example: Bat's Head in Dorset
