At high tide, erosive waves will reach the base of the cliff, and erode a wave cut notch through hydraulic action,, which is the force of the water and abrasion,, which is where sediment is hurled at the cliff., This will increase the size of the notch over time and, the cliff face above is unsupported., Weathering will weaken the unsupported cliff face and eventually , collapse under the force of gravity., The process then takes place again with a wave cut notch , being formed at the base of the cliff., As this process continues again and again, the cliff retreats leaving a , wave cut platform which is a , gently sloping rock exposed , at low tide..
