The four major types of coastlines are emergent coastlines; submergent coastlines; concordant coastlines; and discordant coastlines. Many emergent coastlines have existed since the glacial phases of the Pleistocene Epoch, which lasted from about 2,580,000 and 11,700 years ago because the sea levels were much lower than they are today. Discordant coasts have a crenellated pattern of projecting headlands and indented bays. Discordant coastlines are characterised by different bands of rocks running perpendicular to the coast. Geology [ edit] The form of the coastline around Durdle Door is controlled by its geologyboth by the contrasting hardnesses of the rocks, and by the local patterns of faults and folds. Lulworth Cove is a World Heritage site and part of the Heritage Coastline. A concordant coastline with resistant Portland Limestone forming a protective stratum parallel to the sea.

Waves drag in the shallow water approaching a headland so the wave becomes high, steep and short. On a discordant coastline, alternating layers of hard and soft rock are perpendicular to the coast. Coastlines of Submergence: i. Ria Coast: During the Ice Age a great deal of water was locked up in ice. These form where deposition produces unconsolidated geological structures parallel to the coastline. Coastlines of Submergence: i.

Although now a coastal village, Happisburgh was once some distance from the sea, parted from the coast by the parish of Whimpwell, long since eroded away. This is because access to the coast offers the opportunity for harvesting marine resources, especially fish, as well as the ability to conduct international trade via the sea. This continual process can weaken the joints and cracks in the cliff, causing pieces of rock to break off. A hard rock type is resistant to erosion and creates a promontory whilst a softer rock type is easily eroded creating a bay. What is the Demographic Transition Model?

Concordant coastlines form coves, which are round areas of water that have narrow entries from the sea. Portland limestone erodes very slowly, retreating landwards by marine undercutting and collapse to form a straight W-E coastline. Additionally, hotter temperatures enable extreme weather events like hurricanes to occur more frequently. The coastline determines everything. In accordance with UNCLAS, territorial waters extend 12 nautical miles from the baseline. Consequently, the water from the sea sweeps away the soft rocks leaving behind a circular land formation known as a cove. It can be reached at low tide by walking from the mainland.

This process. The time wind takes to blow, wind speed and the fetch (distance the sea has covered) influence wave sizes. The differing resistance to erosion leads to the formation of headlands and bays. When a wave breaks upon the shore, rocks and pebbles that are being carried collide with each other breaking them and eventually making them smaller and smoother.
