Quizplus · Accepted Answer

A wave-cut platform is formed by the constant pounding of waves on a rocky coastline which gradually wears away the rock. Over time, the sea level gradually lowers relative to the land, exposing a broad, flat platform where the waves once were. Therefore, the presence of a wave-cut platform indicates a lowering of sea level relative to the land.
