Erosional landforms

How are wave cut platforms formed?

Waves erode the bottom of a cliff creating a notch which will deepen until unsupported rock collapses and the cliff will retreat backwards and remove debris resulting in a gently sloped flat rock surface

What is an example of a wave cut platform?

Kimmerage Bay (Dorset) and Cape of Good Hope (South Africa)

How are blowholes formed?

Wave erosion creates a sea cave in weak points of the cliff which erodes upwards due to a vertical crack and a shaft is created which connects the cave to the surface and sea water can spray out with the force of incoming waves

What are examples of blowholes?

Stair hole (Dorset) and Halona Blowholes (Hawaii)

How are headlands and bays formed?

Along the coast there is bands of alternating hard and soft rock and the force of the waves erodes soft rock creating bays and the hard rock is barely eroded resulting in headlands

What are examples of headlands and bays?

Pembrokeshire coast and Half moon Bay (California)

How are cave, arch, stacks and stumps formed?

Erosional processes attack weaknesses in headland and overtime the crack will widen creating a cave, which will eventually occur on both sides creating an arch, then the arch will collapse leaving a stack and it will erode down to a stump

What are examples of a cave arch stack stump?

Old Harry Rocks (Dorset) and Ko Tapu (Thailand)
