Headlands and bays form in areas where rocks such as sand and clay are eroded, leaving stronger rocks behind. Headlands and bays, such as Swanage Bay, form on discordant coastlines, where hard and soft rock run in layers at 90 to the water. The constant erosion of rocky headlands may produce a variety of particular geomorphic structures, including sea arches and sea stacks. While some remain stable, others can lead to landslides. The protected embayments, where wave action is subdued between headlands, are often transformed into sandy pocket beaches.

A headland of considerable size often is called a cape. It all began about 80 million years ago when the Pierre shale, the bottom layer of the Badlands geology, was laid down by a great inland sea. Through the deposition of sediment within the bay and the erosion of the headlands, coastlines eventually straighten out, then start the same process all over again. Seas, a portion of the ocean that is partially enclosed by land, are located at the edges of the oceans. Coastlines where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines. It causes physical weathering of the rocks in warm regions and fragments in the rock in the cold areas when water freezes inside the holes of the rock and expand to create a crack in it and thereby yield sediments. Behind the spit, salt marshes are formed. Broadly, the coastal landforms can be divided into two groups, those formed due to erosion and those formed due to deposition. An example of a headland is the land surrounding a farm. 4) Try Mr G's lights out exercise - look for evidence of weathering and coastal erosion and write the evidence down. Transportation and deposition processes produce distinctive coastal landforms (beaches, recurved and double spits, offshore bars, barrier beaches and bars, tombolos and cuspate forelands), which can be stabilised by plant succession. Edwin. Headlands and bays are features of coasts that are formed by erosion. How are headlands formed by erosion? Alternating layers of hard and soft rock allow the sea to erode the soft rock faster, forming a bay but leaving hard rock sticking out, known as a headland.

Cape Horn is a headland forming the southern tip of South America. 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. The shape and appearance of sea cliffs depends on the stratigraphy, geologic structures, angle of deposition, and lithology of the bedrock material in which the cliffs are formed. Headlands and bays can form when a stretch of coastline is formed from various types of rock. Large water bodies are oceans and bays. Hydraulic action - waves while approaching the coast trap air and push it into breaks of the cliff. Boasting as the worlds highest and most famous mountain peak, Mt.

Headlands are formed from hard rock, that is more resistant to erosion, such as limestone, chalk and granite. Because of increased wave activity found in the midlatitudes, numerous steep cliff slopes exist there, as compared to the high and low latitudes. An example of a headland is a cliff over a sea. Bays are the areas where soft rock has eroded away next to the headland. Kanyakumari is the headland at the southern tip of the subcontinent of India. Sandy beaches are usually found in shallow bays with fewer waves and shallow water. Deposition Deposition occurs when waves no longer have sufficient energy to continue to transport material Between 1.8 million to 10,000 years ago, Pleistocene glaciers carved steep valleys that were eventually drowned by rising sea levels. This means that the bathymetry (the underwater elevation) of the ocean or sea bed also impacts the strength of waves. Resistant bedrock combined with high-energy wind and wave activity will create a steep profile, whereas easily erodible rocks in low-energy environments will create a more gradual profile, for example, the high cliffs of Kalaupapa National Historical Park (Hawaii) versus the gently sloping rocky coastline of Dry Tortugas National Park (Florida).
