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). A wave cut platform refers to the narrow flat area often seen at the base of a sea cliff caused by the action of the waves. Wave energy is dispersed in the bays; deposition is maximum. Massive rocks, such as granite, will normally erode in a uniform manner, whereas layered sedimentary rocks may erode in a step-wise fashion. continuous waves have been crashing against it.

Waves wear down different types of rocks at different rates. As a result, a section of land known as a headland juts out into the sea. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. We saw an arch and several places where beaches were formed. Bays are usually formed where weaker rocks like clay and sand are eroded leaving a band of harder rocks. The name of its location on the Western Cape is confusing. When there are different types of rock along a coastline, the weaker or softer rock, like clay, erode fastest leaving more resistant rock types such as granite, sticking out to create headlands. Headlands are highly vulnerable to further erosion by water and wind and other features such as caves, stacks, arches, and stumps may emanate from them. Highly folded bedded chert is a characteristic rock of the . A graded shoreline is one in which the coastline has been flat and straight due to wind and water action. This slows down the inshore part of the wave and makes the wave 'bend.'. Headlands are formed when the sea attacks a section of coast with alternating bands of hard and soft rock. Other animals that once lived here -- the grizzly bear, gray wolf, and American elk -- are gone. It is formed when the water rises along a slight but important slope due to some net shoreward transport of water when the waves move towards the beach. Caves occur when waves force their way into cracks in the cliff face. The in-situ beauty of the coastal landforms is a major attraction for people and thereby creates tourism opportunities for their country of residence. Wind acts both as an element that erodes the rocks and a force that determines the direction of the waves. Sandy beaches are usually found in shallow bays with fewer waves and shallow water.

Also see Sea and Littoral Caves as part of NPSCaves and Karst. Spits are created through a process called longshore drift, which moves the material along the coastline. As a result of wave refraction, destructive waves concentrate their energy on all three sides of the headland and so it slowly erodes overtime. The earth on which weather moves on has its own effect on the weather. The pounding surf and breaking waves found on rocky coasts have inspired ocean lovers for generations. In other words, it is the process by which the direction of a traveling wave is .

Barrier islands, barrier spits, beaches, tombolos, and dunes are typical features of the sandy coast landforms. These lines of weakness get enlarged and develop into small sea caves. Discordant coastline occurs where bands of differing rock type run perpendicular to the coast. Wave action can erode some areas of a coastline more quickly where there are sand, soil or soft rock layers, leaving hard rock formations to form headlands and other prominent areas along the coastline.

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. Arches are bridges of rock left above openings eroded in sea cliffs by waves. Tides play two types of role in the formation of landforms. 1) Lines of weakness in a headland, like joints or faults are especially vulnerable to erosion. Forces like rainfall and temperature are other factors behind the formation of coastal landforms.

Headlands are formed when the sea attacks a section of coast with alternating bands of hard and soft rock. Due to waves breaking along the coastline, erosion occurs and other landforms such as caves can form on a headland. Rainfall is responsible for transportation of sediment to the coast through the runoff in the form of streams. A cliffed coast, also known as an abrasion coast, is one in which marine action has resulted in steep declivities known as cliffs. 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.

Thus, the wind has a direct and indirect effect on the formation of coastal landforms. Why are headlands and bays formed on coastlines? These processes result in either erosion or deposition, creating different types of coastal landforms. These are visible at Myers Creek and Arch Rock, south of the Pistol River bridge.
