WebHeadlands and bays result from coastlines that are formed of alternate sections of hard and soft rock. The areas of soft rock are more easily and quickly eroded whereas the harder rock is more resistant to processes of weathering and erosion. Where harder rock is present, headlands occur and where softer rock is being eroded, bays are formed ... WebCusps are crescent-shaped indentations that form on beaches of mixed sand and shingle. They are formed where there is a junction between sand and shingle. Once the curving shape is created, swash is concentrated in the small bay that forms in the centre of the cusp. This creates a stronger backwash that removes material down the beach. shark fittings for copper water pipe

WebBeaches are formed from sand, sand and shingle or pebbles. They can also be formed from mud and silt. A sandy beach is usually formed in sheltered bays, where low energy, constructive waves transport material onto the shore. The swash is stronger than the backwash, so the material is moved up the beach. WebThe sea brings sediment to the beach and then the wind redistributes that sediment. When the wind encounters the beach obstacles velocity falls and sediment is DEPOSITED. This makes amount of sand or sediment at the front of the sand dune system, known as an EMBRYO dune.
