A large headland may also be called a peninsula. A peninsula is a piece of land that is nearly surrounded by Water but connected to Mainland via an Isthmus. Long, narrow and high headlands may be called promontories. When headlands dramatically affect the ocean currents they are often called capes. An ocean current is continuous directed movement of Ocean water. A large bay may also be called a gulf, sound or bight. In Geography a sound or seaway is a large sea or ocean Inlet larger than a bay, deeper than a bight, wider than a Fjord In Geography, bight has two meanings A bight can be simply a bend or curve in any geographical feature&mdashusually a bend or curve in the line between land A narrow bay may also be called a fjord if its sides are relatively steep. A fjord or fiord (fjɔːd|fiːɔːd or fiːɔːd is a long narrow Inlet with steep sides created in a valley carved by glacial activity. Any bay may include other bays (for example, James Bay is a bay within Hudson Bay). James Bay (Baie James is a large body of water on the southern end of Hudson Bay in Canada.

Formation

A headland is a piece of land that juts into the sea from the main land coast line. Headlands are shaped by erosion. They are formed when the sea attacks a section of coast consisting of alternating bands of hard and soft rock. The bands of soft rock such as sand and clay, erode more quickly than those of more resistant hard rock such as chalk. This would form a headland.

A bay is an area of water bordered by land on three sides. Bays are found between headlands where there are alternating outcrops of resistant rock and less resistant rock. Waves erode the areas of softer rock more rapidly than the hard rock to form bays.

Geology and geography

Headlands and bays are often found together on the same stretch of coastline. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. A discordant coastline occurs where bands of differing rock type run Perpendicular to the Coast. Geological resistance is a measure of how well Minerals resist erosive factors and is primarily based on hardness, Chemical reactivity and cohesion Bays form where weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, granite) forming a headland, or peninsula. Sand is a naturally occurring Granular material composed of finely divided rock and Mineral particles Clay is a naturally occurring material composed primarily of fine-grained Minerals which show plasticity through a variable range of Water content, and Chalk (ʧɔːk is a soft white porous Sedimentary rock, a form of Limestone composed of the Mineral Calcite. Limestone is a Sedimentary rock composed largely of the Mineral Calcite ( Calcium carbonate: CaCO3 Granite (ˈɡrænɪt is a common and widely occurring type of intrusive, Felsic, igneous rock. A peninsula is a piece of land that is nearly surrounded by Water but connected to Mainland via an Isthmus. Refraction of waves occurs on headlands concentrating wave energy on them, so many other landforms, such as caves, natural archs and stacks, form on headlands. Refraction is the change in direction of a Wave due to a change in its Speed. A cave is a natural underground void large enough for a human to enter "Natural Bridges" redirects here for the US National Monument see Natural Bridges National Monument. A stack is a geological Landform consisting of a steep and often vertical column or columns of rock in the sea near a coast Wave refraction disperses wave energy through the bay, and along with the sheltering effect of the headlands this protects bays from storms. This effect means that the waves reaching the shore in a bay are usually constructive waves, and because of this, many bays feature a beach. A bay may be only metres across, or it could be hundreds of kilometres across. The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International The kilometre ( American spelling: kilometer) symbol km is a unit of Length in the Metric system, equal to one thousand

Sometimes bays form where movements of the earth's crust (tectonics) bring areas of land together, or move them apart. In Geology, a crust is the outermost solid shell of a planet or moon This article discusses the geologic usage for the philosophical or architectural usage see Architectonics ' Or see Plate tectonics. Usually these bays are referred to as seas or gulfs and not bays. This article is about the body of water For other uses see SEA and Seas.

Beach Stability

Beaches are dynamic geologic features that can fluctuate between advancement and retreat of sediment. The natural agents of fluctuation include waves, tides, currents, and winds. Man-made elements such as the interruption of sediment supply, such as a dam, and withdrawal of ground fluid can also affect beach stabilization [1]. A headland bay beach can be classified as being in three different states of sedimentation. Static equilibrium refers to a beach that is stable and does not experience littoral drift or sediment deposition or erosion[2]. Waves generally diffract around the headland(s) and near the beach when the beach is in a state of static equilibrium. Dynamic equilibrium occurs when the beach sediments are deposited and eroded at approximately equal rates[3]. Beaches that have dynamic equilibrium are usually near a river that supplies sediment and would otherwise erode away without the river supply. Unstable beaches are usually a result of human interaction, such as a breakwater or dammed river[4]. Unstable beaches are reshaped by continual erosion or deposition and will continue to erode or deposit until a state of equilibrium is reached in the bay.
