Headlands and bays can form when a stretch of coastline is formed from various types of rock. Continued wave action causes the widened crack or cave to break through the headland and form an arch. Soft rock bands, such as clay and sand, are weaker, so they can be quickly eroded. Erosion characterizes these high-energy environments, which are typically located on active margins with narrow continental shelves (on account of subduction). Your email address will not be published. Headlands are formed as the result of coastal erosion and the tremendous battering power of the sea and its waves coupled with ice, rain, and wind. Bays are bodies of water partially surrounded by land, and they are typically less enclosed and smaller than a gulf. The bands of soft rock, such as sand and clay, erode more quickly than those of more resistant rock, such as chalk.

As a result, most of the breaker energy is concentrated along the relatively short section of the shore around the tips of the headlands, while the remaining wave energy is spread out along the much longer shoreline of the bays. Hydraulic action is the predominant process. The water contains sand and other materials that grind away at the rock until the cracks become a cave. Another type of current that contributes towards the formation of coastline landforms is rip current. 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. It is best known for the difficult westward passage around the cape to the Pacific, particularly by sailing vessels against headwinds and rough seas, strong currents and possible icebergs. Waves usually hit the bottom of the cliff hard during storms and at high tide. These areas are often subjected to changes in environmental forces such as cyclones, tsunami, earthquakes, and climate changes. Headlands and Bays. Coastal dunes are primarily the result of direct impacts of onshore wind movements. Such a cavity is formed in many types of rock and by many processes. Bays are usually found on oceans, lakes, and gulfs, not rivers, except where an artificially enlarged river mouth is present. 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). The exact specifics of these we can cover another time but the basic overview is that these methods of erosion remove sediment from coastal areas. A cliffed coast, also known as an abrasion coast, is one in which marine action has resulted in steep declivities known as cliffs. 5) Try this hot potatoes exercise on Cliff formation.

Kanyakumari is the headland at the southern tip of the subcontinent of India. The sandy coast landforms, mostly located in the passive margins, have extremely dynamic environments that are subject to rapid and severe changes. 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. The ocean's "dynamic" topography tells oceanographers the speed and direction of ocean currents in the same way that maps of atmospheric pressure are used by meteorologists to calculate the speed and direction of winds.
