The headlands on rocky coasts are exposed to intense wave, wind, and storm action. Headlands form along discordant coastlines where bands of soft and hard rock outcrop at a right angle to the coastline (see image below).

Waves wear down different types of rocks at different rates. (Yes. A large headland may sometimes be called a cape. Headland erosion is perhaps one of the best known processes in coastal erosion, where a crack in the headland is opened and enlarged by hydraulic abrasion. Barrier islands, barrier spits, beaches, tombolos, and dunes are typical features of the sandy coast landforms. The areas of softer rock retreat, forming bays, while hard rock is eroded slower, resulting in headlands. For this to occur, Headlands OCEANSCAPE NETWORK. Prominent land extending into a large body of water Headlands and bays, such as Swanage Bay, form on discordant coastlines, where hard and soft rock run in layers at 90 to the water.

Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bedrock composition, climate, and wave patterns dictate the profile of rocky coasts. Headlands, once formed, are exposed to the full force of the sea.

A portion of land that extends from the mainland into a large body of water. These lines of weakness get enlarged and develop into small sea caves. The Marin Headlands are underlain by geological formations created by the accretion of oceanic sediments from the Pacific Plate onto the North American Plate. These coasts are composed of different types of rocks, namely igneous, sedimentary, or metamorphic and are filled with complex tectonic landforms like folds, faults, and igneous intrusions and extrusions. As a result of wave refraction, destructive waves concentrate their energy on all three sides of the headland and so it slowly erodes overtime. Besides having an indirect impact on wind and wave movements, gravity directly determines the downslope movement of sediment and rock. d. rock falling into the ocean along the shore.

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. What landforms are formed inland by erosion? Forces like rainfall and temperature are other factors behind the formation of coastal landforms. Waves wear down different types of rocks at different rates. The outcome of this downward movement is apparent along shoreline cliffs where the sea currents hit the base of the cliffs and the dented slope to cause an ultimate collapse of the rock in the seawater.
