A gently sloping surface produced by wave erosion, extending into the sea or lake from the base of the wave-cut cliff. This feature represents both the wave-cut bench and the abrasion platform (Jackson, 1997). Compare - Submerged Wave-Cut Platform.
A wave-cut platform or marine terrace is the narrow flat area often seen at the base of a sea cliff caused by the action of the waves. It forms after destructive waves hit against the cliff face, causing undercutting between the high and low water marks, mainly as a result of corrasion and hydraulic power, creating a wave-cut notch. This notch then enlarges into a cave.
