When Is a Wave-Cut Notch Formed?

A wave-cut notch is formed by erosional processes such as abrasion and hydraulic action - this is a dent in the cliff usually at the level of high tide. As the notch increases in size, the cliff becomes unstable and collapses, leading to the retreat of the cliff face.

How are wave cut ridges formed?

Wave-cut platforms form when destructive waves hit against the cliff face, causing an undercut between the high and low water marks, mainly as a result of abrasion, corrosion and hydraulic action, creating a wave-cut notch. This notch then enlarges into a cave.

How is a wave-cut platform formed for kids?

This feature is called a wave-cut platform, or wave-cut bench. It is formed by wave abrasion of the bedrock along the coast. A platform is broadened as waves erode a notch at the base of the sea cliff, which causes overhanging rock to fall.
