The formation of the coastal landscape depends on many factors, including the type of rock these processes are acting on, how much energy is in the system, sea currents, waves, and tides. A number of stages are involved: All rocks have lines of weakness; the sea and its waves use hydraulic action, abrasion and solution to erode along any lines of weakness. Also see Sea and Littoral Caves as part of NPSCaves and Karst. Waves must have limited energy for this to occur, so beaches are frequently formed in sheltered areas such as bays. 2) Erosive processes like corrasion and hydraulic action gouge out the rock along the line of weakness to form a cave.

Bays, on the other hand, are created from less resistant rocks. "Badlands National Park" Waves are refracted around the headlands, increasing erosion at seaward positions on the islands in the park. A headland of considerable size often is called a cape. Coastal landforms are the landforms along the coastline that are mostly formed by erosion and sediments from waves, longshore currents, rip currents, tides, and climatic factors like wind and rainfall, and temperature include headlands, cliffs, bays, spits, salt marshes, and beaches. While some remain stable, others can lead to landslides. Spurn Head at the north of the Humber Estuary in the northeast of England is an example of spit. Besides having an indirect impact on wind and wave movements, gravity directly determines the downslope movement of sediment and rock. Fjords are made when glacial valleys are filled with water when sea level rises. Does a Ford GEM module have to be programmed. Headlands are formed through wave deposition. This eventually makes the rock weak. Pocket beaches may be ephemeral and change seasonally, or even disappear, on account of increased energy events. Stacks by rgamesby.
