Long spits of sands run parallel to the low coast, enclosing the coast. Fjords are created when glaciers cut through valleys and are submerged. Approximately 40% of all people live within 100km of a coastline. The time wind takes to blow, wind speed and the fetch (distance the sea has covered) influence wave sizes. They have low energy and an elliptical orbit. The differing resistance to erosion leads to the formation of headlands and bays. Either way, there is now a (bit of) coastline that is no longer submerged under water. What are the causes of deforestation in the Amazon? discordant coastlines. Coastlines where different types of rock alternate between hard and soft rock are called discordant coastlines and will have more bays and headlands along its length . in height. Where the land rises to the sea there are several parallel strata of Jurassic rocks, including Portland limestone and the . . A concordant coastline can take one of the following two landform types: An example of a concordant coastline is Lulworth Cove, again, in Dorset, UK (figure 3). Each process can produce several coastal features; however, they often work together to sculpt the coastlines.

Worksheets with answers provided that guide students through sequencing each landform with the emphasis on process detail and geology. Soft engineering: Beach nourishment is a type of soft approach. The concordant coast may take one of two landform types. The Dalmatian type, named from Dalmatia on the Adriatic Sea, features long offshore islands and coastal inlets that are parallel to the coastline. This results in the formation of headlands and bays. concordant coastlines. The coastline between Durlston Head and Studland Bay in Dorset, UK, is a great example of a discordant coastline. It is used in geography and meteorology and is usually associated with coastal erosion.It plays a large part in longshore drift as well. However, when the hard rocks punctured by either faults or ridges, inland soft rocks yield to erosion. While not every UN member has ratified UNCLAS, most nations abide by it anyway.

The Isle of Purbeck, in Dorset, is an example of where a concordant and discordant coastline exist very close to one another. Discordant coastlines - where the rock layers alternate between harder and softer rock, which bays and headlands are more likely . This belongs to: _____. 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). The outer hard rock is Portland limestone. The high degree of indentation of Bantry Bay is not solely influenced by the relative resistance of rock types, but also the orientation of strata SW-NE means that they directly face high energy Atlantic waves driven by the prevailing SW wind. Coastlines where different types of rock alternate between hard and soft rock are called discordant coastlines and will have more bays and headlands along its length. These act as agents of erosion because their backwashis greater than their swah. Concordant coastlines tend to have fewer bays and headlands. The latter can happen when tectonic forces lowered the land level or when river deposits and compaction of alluvial (river) sediments occur. There are 3 main groups of coastal features which result from coastal erosion: 1. Discordant coasts have a crenellated pattern of projecting headlands and indented bays. pg. Coastlines, where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines. The image below shows the narrow opening created in the limestone and the cove that formed afterwards. Dip is the angle of inclination of titled strata. The procedure for calculating concordant and discordant pairs compares the classifications for two variables (for example, X and Y) on the same two items. Geology is the study of the types of rocks that make up the Earth's crust. The coastline determines everything. The coastal engineering for the shoreline protection involves: . Or built a sand castle next to the waves? Waves are created as wind blows over the water causing friction; this causes the water to start to move in a circular orbit. Transportation is the movement of material from a coastline--such as sand and gravel--while deposition is the addition of material to a coastline. The Earth has approximately 620,000 kilometres (390,000mi) of coastlines and they are not just a barrier between land and water; they are also important natural ecosystems.

Historic records indicate that over 250 m of land were lost between 1600 and 1850. False! The differing resistance to erosion leads to the formation of headlands and bays. high and low energy coasts, geology and sea level and how these change a coastline | GEOLOGICAL structure : which create concordant and discordant coastlines ( Dalmatian and Haff ). Bands of soft rock such as clay and sand are weaker therefore can be eroded quickly. For example the Neman Haff behind the bar running from the Kaliningrad in Russia to the Lithuanian coast at the mouth of the river Neman. The Portland limestone is resistant to erosion; then to the north there is Swanage Bay where the rock type is a softer greensand. Quick revise. Sometimes the outer hard rock is punctured allowing the sea to erode the softer rocks behind.

Rock strata that are less resistant (due to the rock unit's lithology and structure) erode rapidly to form indented bays. 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. Case studies Dorset Jurassic coast and Holderness Extended writing tasks 2 a half term. Concordant coasts form where geological structure is such that different rock strata or folds are aligned parallel to the coastline. Paisajes. Discordant coasts forms where geological structure is such that different rock strata of folds are aligned at an angle to the coastline. Created up folded ridges (anticlines) and down folded valleys (synclines) aligned parallel to the coast. . Bands of soft rock such as clay and sand are weaker therefore they can be eroded quickly. Headlands and bays Cliffs along the coastline do not erode at the same pace. The amount of energy is dependent on the wind speed, the length of time the . Erosion. You know your landforms of coastal erosion. Wave refraction involves waves breaking onto an irregularly shaped coastline, e.g. As our Earth warms, glaciers melt, causing the sea level to rise. Label two landforms shown in the photograph (2) Coasts - Grade Booster. The Early Cretaceous, sometimes known as Lower Cretaceous, is the period stretching from 145 million years ago to 100.5 million years ago. Waves interact with land through three major marine processes: erosion, transportation, and deposition. The shape of the cove is the result of wave diffraction. The fetch, often called the fetch length, is the length of water over which a given wind has blown. A ria coast hosts multiple rias. Discordant coastlines have bands of different rock types running perpendicular to the coast; concordant coastlines have bands of similar rock types running parallel to the coast. 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. Soluble materials dissolve in water and are carried along. A fjord coast hosts multiple fjords. Subsequently there was an increase in the waters of the oceans and the sea level rose appreciably.
