Headlands that jut outward into an open body of water such as an ocean leave the land formations unprotected against years of wind and wave erosion. A large bay is usually called a gulf, sea, sound, or bight. They also host a wide variety of flora and fauna, which are significant for the sustenance of the local ecosystem. Spits are created through a process called longshore drift, which moves the material along the coastline. How Landforms Affect Global Temperature and Weather. Stacks are formed by headlands turning into caves, caves turning into arches and arches turning into stacks. Cape Cod National Seashore in Massachusetts and Cumberland Island National Seashore in Georgia are notable examples of sandy coast landforms. Deposition Deposition occurs when waves no longer have sufficient energy to continue to transport material These are determined by geology, rates of erosion and beach profile. (Yes. 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. 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. . layer of hard rock ie, chalk, and the bay beside it was once III.

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. The headlands are formed by the hard rocks such as limestone and chalk while the bays are formed as a result of the sweeping away of the soft rocks like clay and sand. The river mouths are often deposited with an excess supply of sediments and form a triangular shape landscape like the Greek capital letter delta ().

Soft rock bands, such as clay and sand, are weaker, so they can be quickly eroded. Rainfall is responsible for transportation of sediment to the coast through the runoff in the form of streams. This all happens from erosion and weathering. The area behind a spit is usually a sheltered area where water movement is slow and hence more material gather there as deposits. 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. Lands End is a headland in Cornwall at the southwestern tip of England, extending far out into the Atlantic from most of the island. A headland can also be much larger, forming a cape at one protruding end of an island or a continent. The Mississippi River delta is one such good example.

Bays are water bodies located on a land next to the sea or a lake located between two headlands. 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. 3) Over time, erosion may lead to two back-to-backcaves breaking through a headland, forming an arch.
