A wave-cut platform is a flat surface that is formed when the waves erode the base of a cliff or headland. The flat surface is often covered with gravel or sand, and this can be seen when the tide goes out. The underlying rock is generally harder than the rock above, and this allows for the erosion to happen more easily. The smooth surface of the wave-cut platform is a result of the constant action of the waves over time.
