  1. Topic 5 – Contrasting Coasts GCSE Unit 1 Revision

  2. Coastal Processes • What are the main processes that occur at the coast?

  3. Do you know the definitions? • Erosion (hydraulic action, abrasion …) • Transportation (Longshore drift) • Deposition • Weathering (Freeze thaw) • Mass movement (rotational slumping)

  4. Practice question • Draw a labelled diagram to show how material is transported along the coastline. (4 marks)

  5. What are the strengths and weaknesses of this answer? Is it worth 4 marks?

  6. Erosional Features • Watch the clip, writing the names of landforms you hear. (Do you need reminding what a coastal landform is?!!!) http://www.bbc.co.uk/learningzone/clips/coastal-erosion-and-landforms/9966.html

  7. Formation of Sea Stacks Explain how sea stacks form using the words below. Erosion, cave, arch, stack You could also include: Weakness, stump

  8. Depositional Features • Watch the clip. Afterwards, you will need to draw a labelled sketch of how spits form. • http://www.bbc.co.uk/learningzone/clips/the-formation-of-spits/3246.html

  9. Formation of a spit

  10. Coastal Management • Draw the table: • Watch the clip and fill in the table to compare the 2 locations’ management. • http://www.bbc.co.uk/learningzone/clips/coastal-management-strategies-sea-defences-and-managed-retreat/3243.html

  11. Coastal Management What is the meaning of and advantages and disadvantages of…? • Managed Retreat • Soft Engineering • Hard Engineering
