Many of these types of coastlines were actually formed toward the end of the Last Glacial Period (LGP). Coastlines with the same type of rock along its length tend to have fewer features ad are called concordant coastline. The Isle of Purbeck, in Dorset, is an example of where a concordant and discordant coastline exist very close to one another. Concordant coasts are also known as dalmatian coasts, after the Dalmatian region of Croatia, or Pacific coasts, after the coastline of Chile in South America.

At the start of the Holocene Interglacial (10,000 years BP) led to a rapid 100 m eustatic rise in global sea levels, as 3,000 years of ice sheets and glaciers shrank. Emergent coastlines can have features such as marine terraces, relict sea cliffs, sea stacks, and raised beaches. Fjords are created when glaciers cut through valleys and are submerged. The time wind takes to blow, wind speed and the fetch (distance the sea has covered) influence wave sizes. The sea attacks a weakness in the base of the cliff. While discordant coastlines have bands of different rock types running perpendicular to the coast, concordant coastlines have bands of similar rock types running parallel (alongside) to the coast. Water quality and pollution management in the UK. The differing resistance to erosion leads to the formation of headlands and bays. formed by the erosion of less resistant Wealden Clays. The difference in rock types between discordant and concordant coastlines means that there are differences in erosion. There are four processes involved in the eroding coastlines. These coves are formed by waves breaking through an outer layer of hard rock, such as limestone, and then, over time, the waves sweep away the soft rock further inland, like sand and clay, creating a cove. 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. Concordant coastlines - A coastline parallel to the land structures which form the margin of an ocean basin. The coastline determines everything. Geological structure is the characteristics and arrangement of rock units. A coastline with the same type of rock along its length; fewer bays and headlands . The relatively gentle profile of the beach with a steep ridge at the top of the beach means that the backwash soaks into the sand or slowly drains away. Wave diffraction happens when the narrow opening to the cove causes the waves to bend, creating an arc shape wave. If the coastline is discordant then the rock type will change as we go up the coastline, An example of a discordant coastline is swanage. When the auto-complete results are available, use the up and down arrows to review and Enter to select.

Concordant and discordant coastlines Caves, arches, stacks and stumps Caves, arches, stacks and stumps are all features of a weathering or erosion process at different stages. CAVES, ARCHES, STACKS AND STUMPS These are found on headlands where wave refraction means that erosion takes place on both sides of the headland. Coastlines are constantly changing, with sea levels rising or falling, and it is no different with submergent coastlines. Resistant Cretaceous Chalk forms the Foreland headland, projecting 2.5 km to the north. This quiz focusses in particular on those features which are caused by coastal erosion. Concordant Coasts . Bands of soft rock such as clay and sand are weaker therefore they can be eroded quickly. in height. A hard rock type is resistant to erosion and creates a promontory whilst a softer rock type is easily eroded creating a bay. Concordant. The shape of the coastline (which is dependent on its geology) - on concordant coastlines, rocks are parallel to the wave front and therefore rates of erosion are similar along the coastline. If the coastline is concordant then the coastline will have the same type of rock all the way down the coastline, because the ropck is running parallel to the coastline. Emergent coastlines have emerged from the water; submergent coastlines have submerged below the water. concordant and discordant coastlines bbc bitesize - hillsboro, ohio newspaper classifieds - hillsboro, ohio newspaper classifieds - (For example the east of the Dorset coast) How Geology affects the coast .

What are the physical characteristics of cold environments? Adapted from BBC. The Bay is also a product of sea level rise, since river erosion cut a low-relief river valley into Carboniferous Limestone, allowing the sea to flood inland and creating a ria at the start of the Holocene.

A fjord coast hosts multiple fjords. Practice Questions: Slideshow 2773107 by chanel Coasts Revision Booklet. full verbatim. the same rock types are parallel to the coastline, with alternating bands of different rock types running parallel to the coastline behind it (as opposed to a 'discordant coastline' where the rock types are perpendicular to the coastline, presenting differing rock types to the sea along the coastline). That is, if both the row and column index move in the same direction - both increase or both decrease, then the pair is concordant. 5 July 2020 / in AQA GCSE Geography , Coasts , Landforms of Coastal Erosion / by Anthony Bennett A discordant coastline is where the geology alternates between strata (bands) of soft and hard rock.
