Bay usually is smaller and less enclosed than a gulf. A number of stages are involved: All rocks have lines of weakness; the sea and its waves use hydraulic action, abrasion and solution to erode along any lines of weakness. 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. 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. Privacy Policy .

Lands End is a headland in Cornwall at the southwestern tip of England, extending far out into the Atlantic from most of the island. Headlands are formed from hard rock, that is more resistant to erosion, such as limestone, chalk and granite. Rocky coasts may be composed of any rock type (i.e., sedimentary, igneous, or metamorphic) and are usually the site of complex tectonic landforms such as faults, folds, and igneous intrusions and extrusions. These caves are distinctive environments that are particularly suited for bryozoans, sponges, barnacles, tubeworms, and some species of shade-tolerant red algae. [4] These are formed when cliffs of hard rock erode more slowly than the surrounding softer rock does. c. wind blowing across the water's surface. Photographs taken just 50 years ago show different formations than those seen today; this is the result of unusually rapid erosion. 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. 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. Plate tectonics, which involves continents drifting together and rifting apart, is responsible for the formation of numerous large bays. ; If the cave is formed in a headland, it may eventually break through to the other side forming an arch. These are determined by geology, rates of erosion and beach profile. Another type of current that contributes towards the formation of coastline landforms is rip current. This means that the bathymetry (the underwater elevation) of the ocean or sea bed also impacts the strength of waves. How is a Headland formed? An example of a headland is a cliff over a sea. Continued wave action causes the widened crack or cave to break through the headland and form an arch. Prominent land extending into a large body of water Methods of coastal erosion can include; hydraulic action, attrition, solution and abrasion. How do headlands and bays form on discordant coastlines? Bays are usually smaller than gulfs, though this isnt always the case. The formation of the coastal landscape depends on many factors, including the type of rock these processes are acting on, how much energy is in the system, sea currents, waves, and tides. Headlands and bays are often found on the same coastline. A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water.

Rainfall is responsible for transportation of sediment to the coast through the runoff in the form of streams. A bay is a recessed, coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or even another bay. The area behind a spit is usually a sheltered area where water movement is slow and hence more material gather there as deposits. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out. Headlands and bays are often found on the same coastline.
