isostatic recovery takes place (slowly/over a long period of time) AO1 content encompasses knowledge and understanding of the factors that contribute to high energy/erosional landforms, with the knowledge of the processes involved in their formation. An examination of human impacts that increase or decrease erosional processes reference to types of reefs - fringing, barrier, atoll description of suspension, saltation and traction with link to grain size reference to vertical growth of reef, in-line with changing sea levels. The formation of landforms over one or more of these time scales should be related to processes. Recognition that the role of marine processes can vary for the same landform between locations. Landscape of blue carbon research from the perspective of bibliometrics. A geographical context for the management strategy Human activities shape the structure of landscapes in different ways and hence modify animal communities depending on the type and intensity of these activities. Part of Springer Nature. Examine the strengths and weaknesses of one strategy used to manage the impacts of human activity on coastal landscape systems. the extent to which the strategy has reduced impacts on human activity cluster in North Wales Strength of winds - some places may be affected by strong winds whilst others may be sheltered CERC (1984) Shore protection manual, vol 1. The coastline is rapidly eroding at an average of 1.8 metres a year. Headland has developed (a) (ii) Suggest one social loss associated with coastal erosion. Knowledge and understanding of conditions and process of deposition weight of glaciers causing compression (b) Explain the formation of either coral reefs or mangrove coastlines. Exact location? Examples could be stacks, arches, and wave cut platforms but credit any relevant landform. Major cities like New York are right next to the sea. The cost of this over the years is well into the millions and although replenishing the beaches with sand is helpful now, it is hardly a long term solution (Fox). Dont include personal or financial information like your National Insurance number or credit card details. We use some essential cookies to make this website work.

The content may vary according to the landform but may include: [5], All have landslides as the highest % * The sand dunes on the beaches. Location 2 shows less fluctuation in rates of erosion (a) Label Figure 1b to explain the processes responsible for the formation of landform X. - Cliffs: 962928, 13. It will take only 2 minutes to fill in. The high cost of London properties has caused for businesses to move out towards the coast, Many UK coastal resorts have universities and young populations that allow companies to expand there. . Size of particles - some places consist of particle sizes easier to erode by wind e.g. Replacement of track most expensive Coastal zone 89. Despite the negativity surrounding the current state of our Ocean, the good news is that its not too late to turn things around. Where areas suffer from high levels of erosion different protections strategies are implemented to protect the coastline. AO1 AO2 content encompasses the application of knowledge and understanding to examine the role of erosional processes in the formation of landform(s). We also use cookies set by other sites to help us deliver content from their services. Beach erosion is widespread and causes significant problems for both the use of and protection by beaches. Professor Lora Fleming, Director of the Exeter University European Centre for Environment and Human Health, said: This project has shown that our coast helps to cater for a variety of human needs, from keeping healthy, to connecting with others. Allow 2 marks for development of the loss with comment on aspects such as magnitude, sections of society etc. The content may vary according to the landform but may include an examination of: An examination of the scale of the role of erosional processes (a) (ii) Explain why changes in sea level take place over millennia. Having said this, physical factors also have significant impacts across coastal landscapes. Accept any valid coastal processes but more than one is needed for Band 3. Major cities like New York are right next to the sea. Answers may conclude that longshore drift has a major part or variable influence on the development of selected landform(s). ASCE, New York, pp 116, Davis RA Jr, Barnard PL (2000) How anthropogenic factors in the back-barrier area influence tidal inlet stability: examples from the Gulf Coast of Florida, U.S.A. knowledge and understanding of how structural geology influences the development of the selected landform(s) - this may include reference to mineral composition, solubility and hardness. the extent to which modification of processes operating in a coastal environment has been successful Now the coast has been fished out. -Colour of land, Coral reefs Usefulness of Graphs: Examination of the role of other processes This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The human impact on the environment is the sum of all activities and behaviors that create both positive and negative changes that affect the Earth's sensitive ecosystem. Weybourne only has landslides The extent to which associated factors such as mass movement, marine erosional processes, geological factors etc. They are a vital part of maintaining our beaches as they absorb the impact. knowledge and understanding of the reasons why a management strategy is required such as erosion of coastal dunes by tourists, destruction of coral reefs, erosion as a consequence of the use of groynes knowledge and understanding of the characteristics of the management strategy which could include physical structures and operations The Ocean Conservation Trust is a charity of Ocean optimists taking action to protect and restore nature for a thriving Ocean. 5. CERC, 1984. This leaves the sand dunes more susceptible to erosion causing blowouts and disrupting the succession of vegetation in the area. 2019, p. 247). The report also warns that in the coming decades, climate change and extreme weather has the potential to jeopardise sensitive marine habitats, demonstrating the importance of the UKs network of Marine Protected Areas. (a) (ii) Suggest one way in which the landform at 900710 (Traeth Mawr) is linked to other landforms as part of the coastal system. AO2 Candidates should demonstrate application of knowledge and understanding through an examination of the extent to which one coastal management strategy has been successful. Traeth Mawr, 17. Part of Springer Nature. 2. Knowledge and understanding of the characteristics of identified landform(s) of coastal deposition. Various structures such as seawalls, groins, and breakwaters have been constructed to help protect beaches from erosion. Bar charts, cumulative bars and pie charts Knowledge and understanding of how alternative process contribute to the development of depositional landforms. Usefulness: Human activities add another layer of complexity to the natural processes of coastal lands and materials. - parts of mangrove furthest from low watermark have less erosion (1). Changes of boundaries, ie choropleth. In this study, we attempt to address this issue by simulating the spatial interactions among natural hazards, ever-increasing human activities, and social vulnerability in the south coast of the Bohai Sea, China. The human cost of flooding can be large, but events like this have a big impact on the natural world too, and the effects are not always negative. 2. Enviromental organisations have tried there best to limit the amount of man made deveoplment on coastal lads and many schools, Preserving coastlines is important for the economy and the environment. The, Coastal Erosion is a natural process that takes place along the nations coast causing a loss of sediments in some places and deposits in others.3. (b) Assess the positive impacts of human activity on the coastal landscape at one or more locations. All points on scale? (a) Use Figure 2 to describe the pattern of sediment gain and loss along this coastline. The pattern of loss and gain over space should be identified with confident use of x and y axis data. [8], AO1 Erosion of the 12 apostles (only 9 left) has nothing to do with humans, where dramatic oil spill near coast ruins beaches, does have to do with humans. Summary of beach nourishment along the U.S. Gulf of Mexico shoreline. dredging of sands and gravels. Field Sketches: -Transport, Remind students that many human activities not associated with the marine environment can also affect ocean ecosystems. AO2 Candidates should apply knowledge and understanding to evaluate the impacts of human activity on the coastal environment. People use the coast for a variety of needs: Although we love the coastline we have had a major effect on it. The geological structure incorporates bedding planes, dip, folding and faulting and can add distinctive features to these landforms. (Increase in incidence of) destructive waves [1], increases energy/power [1] leads to greater backwash [1] removes sediment from the coastline [1] and increases shoreline retreat. Internationally the UK continues to push for greater protection of marine habitats on the world stage with 20 countries joining the UK-led Global Ocean Alliance, which aims to secure protection for at least 30% of the worlds oceans by 2030. the importance of erosional processes or sub-aerial processes Fishing nets get dumped all around the world because they have escaped or they have been cut off. AO2 content encompasses the application of knowledge and understanding to evaluate the importance of longshore drift in the development of selected depositional landform(s). [2], linear clefts in a cliff / narrow inlet, 4. [5], wave height reduced with increased distance inland for all forests, 4. [6], Possible approaches may include: Overbuilding and extensive paving of shorelines can result in destruction of habitats and disruption of land-sea connections such as sea-turtle nesting spots. The content may vary according to the landscape but may include: the characteristics of the strategy such as physical structure or operation Knowledge and understanding of the characteristics of identified landforms that are linked to this scale and their link to process [5]. -Infrastructure [8], AO1 Lack of groundwater - some areas may be drier and so the sediment dries out and easier to erode by wind geographical context 3.6 billion People live near or around a coast. Focus is on differences in deposition rather than comparison of deposition and erosion. All storm water drains in Victoria are linked to the sea. AO2 content encompasses the application of knowledge and understanding to evaluate the importance of seasonal processes and their link to landform(s). -Retail, the movement of sediment may keep harbours clear and accessible Assessment of positive against negative impacts There are 4 key areas which have affected the coastline: Its common in parts of the UK for Crowded Coasts to be used as a term, Many people who work in London can no longer afford housing there, so some commute in from coastal towns and cities (Brighton). (b) Examine the role of marine processes in the formation of one or more landforms of coastal erosion. Give your answer to 2 decimal places. AO2 New York: ASCE, Coastal Zone 89, pp. The price of good farmland has risen sharply, from 2400 per hectare in 1995 to 30,000 in 2015. Marshland and wetland is used to by farmers for grazing pasture for cattle: Industry battles alongside coastal tourism. Knowledge and understanding of the process of longshore drift Harbors and the navigational channels leading to them have resulted in some problems for estuaries. Research shows that underwater noise from construction, shipping and naval vessels significantly impacts the natural behaviour of cetaceans and many other marine species. Protection, management and conservation of dune systems - replanting . In Stauble, D.M. meltwater moves to oceans AO1 (a) Use Figure 2 to describe the pattern of wave energy. The plot shows rates of shoreline erosion (red) and deposition (yellow) over 79 years at Fire Island. Changes in Earth's climate have different effects in different areas of the world. These activities may have direct or indirect effects on our changing coasts. Herein, bacterial communities and soil carbon content in coastal wetland native areas . This has happened for many year. Assessment of positive impacts over time - increase or decrease Many of these are primarily the result of human actions and include ecosystem and landscape changes, sedimentation, pollution, over-abstraction and climate change.. Do the unofficial footpaths have a detrimental/positive affect on species, . Here, we used a multispecies occupancy model (MSOM) to understand mammalian habitat use patterns across a mosaic of tropical dry forest in Colombia and elucidate whether forest cover is more important than its integrity and other . [3]. 2. They may affect sources of new sediment to the coast and the movement of sediment within the coastal environment; they may promote changes in sea level, both local . With increased urbanisation, tarmac and other manmade land surfaces contribute to petrol, diesel and other harmful chemicals easily flowing into rivers or directly into the Ocean. examination of wave types to show how more constructive wave action can increase deposition the role of physical objects at the strand line Coastal erosion is to blame. The sandy beach is the junction of land and ocean. Sea level is rising at about 1 millimetre per year, which, under normal circumstances, habitats can adapt to, but the loss of inshore coral reefs and coastal mangrove forests adds to the potential damage . Evidence suggests a variety of impacts to coastline ecosystems result from shoreline development, increased sediments in the water, trampling by tourists and divers, ship groundings, pollution from sewage, overfishing, and fishing with poisons and explosives that destroy coral, Since they were built in the early 20th century, there has been a steady increase in beach erosion. Beach Nourishment and Protection. [10]. Lynch-Blosse, M.A., and Davis, R.A., 1977. In this paper, we comparatively evaluate changes in the positive and the negative ecological elements of Shenzhen's coastal zone in the rapid urbanization process to understand impacts of human activities. knowledge and understanding of the characteristics of the chosen landform(s) and how these are related to the development through weathering, mass movement and erosional processes for each of the above points allow support from resource for 1 development mark in each instance. (a) (i) Compare the characteristics of the coastal landscapes shown in Figure 1. Beaches Knowledge and understanding of the characteristics of identified landforms that are linked to this scale and their link to process -+ shows change and that the angle of the line is able to indicate rate of change. 15. "To fail the Amazon is to fail the biosphere, and we fail to act at our own peril." #amazon #humanimpact #agriculture #deforestation #landusechange spatial scale of process increases with time - micro scale over minutes whilst macro over centuries Shore Protection Manual, Volume 1. By the time new sand was brought to the beach in 1991 to replenish what was eroded, there was hardly anything left. Geological Society, London, Special Publications 175, pp. Presence of soft rocks - some places may consist of rocks that are made from less resistant minerals or bound together with soft cements The way the coast is managed can cause conflict. Material from beach can be used to erode cliffs/WCP Protection, management and conservation of dune systems - replanting, boardwalks, areas not for public use Protection, management and conservation of mangroves - replanting, nature reserves Protection, management and conservation of coral reefs - managing pollution by industrial and domestic waste, harmful fishing techniques, managing tourism, global warming (a) (i) Use Figure 2 to describe variations in the percentage of properties at risk from coastal erosion and flooding.

Create your own unique website with customizable templates. Sadly, oil spills still occur, coating beaches, sinking to smother Ocean plant life and killing a wide variety of birds, fish and sea mammals. The United Nations have declared that the next decade will focus on Ocean Science and ecosystem restoration. It was not long before attempts to control erosion resulted in various types of structures such as jetties, groins, and seawalls. Encyclopedia of Earth Science Series. There are, however, a number of evidence gaps which we wish to further explore, such as the effects of marine environments on obesity prevalence in children and Vitamin D in adults, or the life stage at which nature-based interventions are most effective, and how they may vary among economic, social and cultural groups in the population. temporal variations in success, 11. - vegetation can consolidate sand dunes, EDEXCEL geography coasts topic + exam style q, Evaluate the view that rates of coastal reces, ES2002 - Metamorphic Petrology and Processes, ES2003 - Ocean Circulation and Chemistry Week, The Language of Composition: Reading, Writing, Rhetoric, Lawrence Scanlon, Renee H. Shea, Robin Dissin Aufses, Edge Reading, Writing and Language: Level C, David W. Moore, Deborah Short, Michael W. Smith. Landforms include headlands, cliffs and wave-cut platforms. Concerns arising from the pollution of coastal and marine waters from land based sources are well established. There graph shows distinct zones that could be used to identify patterns. 3. (a) (i) Use Figure 2 to describe the links between time, space and process. [5], Expensive overall can contribute to the formation and/or development of the landforms identified, 12. The metals required in our laptops, phones and batteries can be found on the seafloor but what damage will we do? (b) Suggest two reasons why the rate of deposition varies along a coastline. Physical weathering/disintegration by such processes as freeze-thaw action, salt crystallisation, and wetting and drying. period of time have increased the size of the beach. Clear links should be made between the processes and the formation of the landform itself. The specification identifies the following landforms as depositional - beaches, spits, bars, tombolos and cuspate forelands. (a) (ii) Suggest one social impact that could have resulted from the high energy storm events shown in Figure 1. Write the correct word in the space next to each definition. (a) Use Figure 1 in the Resource Folder to identify and locate two landforms on the section of high energy coast from Linney Head (883957) to St Govan's Head (975927). In England, 271 million recreational visits are made to coastal environments annually and more than 22 million people live within 5 miles of the coast. Wetlands are constantly adjusting to disturbances occurring within them and within the surrounding landscape. concentration in South East Wales [6], Candidates should show understanding of how the identified reasons can lead to more deposition occurring in one place than another.
