A wave cut platform is made at a place where there is a cliff next to the sea.

Destructive waves slowly erodes the cliff by Attrition and Hydraulic Action

High Tide

Low Tide

Attrition occurs between high and low

tide- rocks are hurled at the base of

the cliff.

Wave Cut Notch

Eroded material is

now available to take part in Attrition.

Cliff is undercut by hydraulic

action, leaving it unstable. This

leaves a cave.

Nothing is supporting the cliff above.

Cliff retreats

Wave Cut Platform- left

exposed.

Wave Cut Notch

The process of Attrition will

continue…

Cliff is unstable, gravity

forces it to

collapse.

Cliff retreat continues over

time

Wave Cut Platform gets bigger, is

eroded smooth by Abrasion.
