A headland of considerable size often is called a cape. 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. Headlands are surrounded by water on three sides. There are four types of erosion by waves: The longshore currents are created when waves are refracted while entering into shallow water. Required fields are marked *. According to NationalGeographic.com, bays are formed through various ways, such as plate tectonics, overflowing of the ocean to a coastline and the slicing of a glacier through a bedrock. 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. [4] Caves occur when waves force their way into cracks in the cliff face. This results in the areas of softer rock to retreat, forming bays, whilst the hard rock is eroded slower so will form headlands. Coastal landforms can be formed either by erosion or by deposition.

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. Rivers and glaciers also cause coastal erosion to form bays. Bays form where the waves erode soft rocks , but headlands are left as land that juts out into the water. 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.
