wave-cut platformor abrasion platformGently sloping rock ledge that extends from the high-tide level at a steep cliff base to below the low-tide level. It develops as a result of wave abrasion; beaches protect the shore from abrasion and therefore prevent the formation of platforms. A platform is broadened as waves erode a notch at the base of the sea cliff, causing overhanging rock to fall. As the sea cliffs are attacked, weak rocks are quickly eroded, leaving the more resistant rocks as protrusions. abrasion platform [ə′brā·zhən ′plat·fȯrm] (geology) An uplifted marine peneplain or plain, according to the smoothness of the surface produced by wave erosion, which is of large area.
