![]() As the notch increases in size, the cliff becomes unstable and collapses, leading to the retreat of the cliff face.A wave-cut notch is formed by erosional processes such as abrasion and hydraulic action - this is a dent in the cliff usually at the level of high tide.The sea attacks the base of the cliff between the high and low water mark.A wave-cut platform is a wide gently-sloping surface found at the foot of a cliff.Ī wave-cut platform is formed when the following occurs: Soft rock erodes quickly and forms gentle sloping cliffs, whereas hard rock is more resistant and forms steep cliffs. Cliffs and wave-cut platformsĬliffs are shaped through erosion and weathering. Bays are more sheltered with constructive waves which deposit sediment to form a beach. Įrosional features such as wave-cut platforms and cliffs can be found on headlands, since they are more open to the waves. When the softer rock is eroded inwards, the hard rock sticks out into the sea, forming a headland. Hard rock such as chalk is more resistant to the processes of erosion. A bay is an inlet of the sea where the land curves inwards, usually with a beach. When a stretch of coastline is formed from different types of rock, headlands and bays can form.īands of soft rock such as clay and sand are weaker therefore they can be eroded quickly. ![]() Headlands and baysĬliffs along the coastline do not erode at the same pace. ![]() The process of erosion can create different landforms along the coastline.
