Have you ever gone for a stroll on a beach? How has rainforest vegetation adapted to the climate? Less resistant rocks are eroded more than the resistant . Large colonies of sea lions and seals sleep and breed along coastlines, entering the seas to hunt. The differing resistance to erosion leads to the formation of headlands and bays. Destructive waves are usually . Jamaica Case Study, How can the growth of tourism reduce the development gap? The water. Correct! The water. Practice Questions: Describe the differences between a concordant and a discordant coastline (4 marks) Explain how headlands form (3 marks) Explain how coves are formed (3 marks). The outer layers of the coastline, those directly on the waterline, are Portland and Purbeck limestone, and they have been eroded away over many years. Take a look at our resources under Topics in the menu at the top of the page. The Dorset Coast contains a range of landforms including Durdle Door, Lulworth Cove .

Shingle ridge reconnected island of Portland Bill to land (a tombolo). The outer hard provides a protective barrier to erosion of the softer rocks further inland. The discordant coastline runs from Studland Bay to Durlston Head as the geology changes from clay and sands, to chalk, to clay and . Now you can find what you're looking for wherever it lives. It is used in geography and meteorology and is usually associated with coastal erosion.It plays a large part in longshore drift as well. Many of our major cities have developed along oceanic coasts as well: think of New York City, Tokyo, Istanbul, Dubai, Hong Kong, and Copenhagen, just to name a few! Coastlines, where the geology alternates between strata (or bands) of hard rock and soft rock are called discordant coastlines.

How do changes affect the balance of an ecosystem? It is also known as Pacific type coastline, longitudinal coastline, or Dalmatian coastline. How did the temperate deciduous woodland get like this? Secondly, erosion of concordant coastlines results in the formation of coves while the erosion of discordant coastlines results in headlands and bays. Long offshore islands and coastal inlets are running parallel to the coastline. concordant coastlines. A coastline with the same type of rock along its length; fewer bays and headlands . The Isle of Purbeck, in Dorset, is an example of where a concordant and discordant coastline exist very close to one another. This area of the Jurassic coastline provides a habitat for a diverse range of natural life, particularly butterflies. Lulworth cove is a perfect horseshoe bay found on the south coast of England in the county of Dorset, on the Jurassic coastline. True or False: As sea levels rise, coastlines are likely to expand. The Adriatic Sea itself is a concordant landform, consisting of a body of water between parallel ranges. This cove is located near the village of West Lulworth and is one of the best examples of a concordant coastline. 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. Swam in the ocean? In accordance with UNCLAS, territorial waters extend 12 nautical miles from the baseline. Ria coastlines are a type of submergent coastline, but Dalmation landforms are associated with concordant coastlines. How is a cold environment interdependent? Sandridge formed bars across some bays and river mouths, with trapped river water forming a lagoon behind (callled haffs in Poland on the Baltic Sea). The hard rock acts as a protective barrier to the softer rock behind it preventing erosion. Coastlines will expand as climate change continues. What is the impact of humans on the temperate deciduous woodland? . As a result, it does not travel far up it. Touch device users . In 2001 it was inscribed as a World Heritage Site by UNESCO for the outstanding universal value of its rocks, fossils and landforms. Either way, there is now a (bit of) coastline that is no longer submerged under water. The rise in sea level can be the result of an increase in water volume or the sinking of the land's surface. These processes are happening constantly and usually work in conjunction to produce coastal features. Both concordant and discordant. Where are the areas of water deficit and surplus in the UK? Examples of discordant coastlines are Bantry Bay and Dingle Bay found in Ireland while an example of a concordant coastline is Lulworth Cove. Headlands and bays Cliffs along the coastline do not erode at the same pace. The water, with an endless supply of waves, whether pounding or gentle ripples, is constantly changing coastlines around the globe. https://commons.wikimedia.org/wiki/File:Lulworth.png. Destructive waves are usually very high, over 1m. Meanwhile on concordant coastlines, where layers of rock run parallel to the coastline, cliffs are much more dominant. As our Earth warms, glaciers melt, causing the sea level to rise. In some cases it is estimated that there was a rise . How is urban planning improving the quality of life for the urban poor in Rio de Janeiro? 3.1B Transport Technology and Globalisation, 3.2 Political and Economic Decision Making, 7C Economic Development and Environmental Impact, 8B Controlling the Spread of Globlisation, 4A.1B Economic Activity and Social Factors, 4A.1A Changing Function and Characteristics, 4A.6 Evaluating the need for Regeneration, 6C Representation and Need for Regeneration, 10A Measuring the Success of Regeneration, 12A Restructuring and Contested Decisions, 7.5 Superpowers and International Decision Making, 7.6 Superpowers and the Physical Environment, 7.6C Middle-Class Consumption on Emerging Powers, 7.8A Emerging Powers and the Developing World, 8.2 Variations in Health and Life Expectancy, 8.3A The relationship between economic and social development, 8.5A Human Rights Vs Economic Development, 8.8 the Positive and Negative of Development, 2B.2C Geological Structure and Cliff Profiles, 2B.3B Rock Strata and Complex Cliff Profiles, 4C Coastal Landscapes Produced by Erosion, 8C Temporal Variations in Coastal Recession, 9A Local Factors that Increase Coastal Flood Risk, A - Economic and Social Losses from Recession, 2B: 12 Integrated Coastal Zone Management, 1B Importance and Size of Stores and Fluxes, 5.4 Deficits within the Hydrological Cycle, 5.8 Consequences and Risks of Water Insecurity, 8A - Causes and Pattern of Physical and Economic Scarcity, 5.9C Integrated Drainage Basin Management, 6.1C - Geological Processes Releasing Carbon, 6.2 Biological Processes Sequestering Carbon, 6.3 Human Activity Altering the Carbon Cycle, 6.6C Radical Technologies to Reduce Carbon Emissions, 6.7 Human Activity Threatening the Carbon and Water Cycles.

Spits were formed in river mouths where the river was powerful enough to break through the sand ridge to the sea. Numerous plants and animals have adapted to live along coastlines. Specification and other support materials for teachers, including delivery guides Explore. Rock strata that are less resistant (due to the rock unit's lithology and structure) erode rapidly to form indented bays. 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 . It is where salts and acids within the seawater will gradually dissolve some types of rock found along the coast. This produces lines of narrow islands parallel to the coast formed by projecting sections of anticlines. What factors influence the effects and response to tectonic activity? Caves occur when waves force their way into cracks in the cliff face. Landscapes. Sustainable development in the Temperate Deciduous Woodland. Concordant Coasts Concordant coasts form where geological structure is such that different rock strata or folds are aligned parallel to the coastline.
