  1. Unit 1 Topic 5– Coastal Change and Conflict On your A3 sheet: What key terms can you remember?

  2. Coasts – foundation question 1. Name the process that moves material along the coastline: (1 Mark) 2. Outline the the process of longshore drift. Use diagrams to help. (2 Marks) What are the triggers in these questions? Have a go!

  3. 1. Longshore Drift 2. What did you get?

  4. Coastal change and conflicts Typical higher exam question: (6Marks) For a named location, explain the costs and benefits of using hard engineering techniques to protect a coastline from erosion. Have a go! Plan your answer What are the triggers in this question?

  5. What did you get?

  6. A* answer? In Christchurch Bay, groynes have been built and used to trap sediment. Although the groynes are expensive to build it has increased the size of the beach protecting the cliff. It has also encouraged residents/business owners to stay in the area people feel confident that erosion and flooding had been controlled. Groynes can look unattractive and will effect the natural processes. Some environmentalists feel that the groynes effect natural processes too much as well as being an ugly form of sea defence. Or In Blackpool a sea wall has been built. Although the wall was expensive to build it did encourage development of the seafront as businesses felt confident that erosion and flooding had been controlled. Due to the size of the sea wall, access to the beach can be difficult. Some Blackpool residents feel that the sea wall has become an ugly barrier keeping tourists away from one of the resorts main attractions.

  7. Case Studies: What are they?

  8. Case studies • Concordant and Discordant Coastlines in Dorset/Swanage • Christchurch Bay – Barton on Sea • Hurst Castle Spit? • Happisburgh?

  9. More exam questions • Identify a coastal landform (usually a photo/sketch pointing to one!) • Identify two differences between constructive and destructive waves. [2 marks] • * Using named examples, explain the costs of two different methods of coastal management. [6 marks] • Name the method of hard engineering shown at A. [1 marks] • Name and describe one process of coastal erosion. [2 marks] • *Explain how a spit is formed. You may draw a diagram(s) to help your answer. [6 marks] • Suggest one reason why Flamborough Head is a popular destination for tourists. [1 mark] • * For two different types of sea defences, explain how they reduce erosion. [6 marks
