Coastal CA prep

  1. 1. Welcome back year 10!
  2. 2. Folders• Name / Geographical Investigation / 10R• Write your target grade & required mark: A* = 34/36 A = 32/36 B = 30/36 Important: C = 27/36 Anyone getting above a C D = 23/36 overall needs to get at least 40/60 for their controlled assessments
  3. 3. Controlled Assessment Due: 1st June Fieldwork Focus : Coastal Management
  4. 4. Controlled assessment title“HOW DO GEOMORPHIC PROCESSESAFFECT YOUR CHOSEN STUDY AREA?”
  5. 5. Important information Location: Hengistbury Head, DorsetTrip date: 25th April (compulsory)Worth 36 marks, 15%Workshops Wednesdays & during Easter/May half term
  6. 6. What can you remember about coasts?Processes?Landforms?Management?
  7. 7. You will need to be able to do thigns like this:Q: “With the use of a diagram, explain theprocess and effects of longshore drift” [4marks]
  8. 8. Useful links….• http://www.bbc.co.uk/schools/gcsebitesize/ge ography/coasts/coastal_processes_video.shtml• http://www.bbc.co.uk/schools/gcsebitesize/ge ography/geographical_skills/controlled_assess ment_rev2.shtml
  9. 9. Types of coastal erosion?
  10. 10. Erosion is……. the wearing away of materials by one of four processes: Corrosion = chemical reactions of salt water weakening rocks like an acid Attrition = Pebbles hitting into each other or intocliffs making rocks break and get smaller and rounder Abrasion = ‘sand paper’ effect. Waves throwing smallstones and pebbles at cliffs and beaches to smooth thematerial Hydraulic Action = Power of the water forcing its wayinto cracks and weaknesses in rocks, splitting apart
  11. 11. The main landforms created by erosion are…
  12. 12. Headlands and Bays
  13. 13. What about waves?
  14. 14. If you were a wave, and you wanted to grow big and strong so youcould knock the UK’s block off, which direction would you come from? Why?
  15. 15. Waves• There are two main types of waves:• Constructive vs Destructive
  16. 16. So, the controlled assessment How does it work?
  17. 17. Example controlled assessments from last year• Take a look at what you will be producing• You will have prep time before the trip, then the trip on 25th April, then the analysis afterwards• Key things = keywords, theory, analysis, explanation, evaluation
  18. 18. Example checklist
  19. 19. What does the markscheme look like? How will you be marked?Look at last year’s examples – peer assess
  20. 20. HOW DO GEOMORPHIC PROCESSESAFFECT HENGISTBURY HEAD?
  21. 21. Mindmapping key questions• Break the essay question down into 3 or 4 key questions that you could investigate• Key questions are essential• Think up questions, think how you could answer them – what data would you need to collect
  22. 22. Key questions?E.g.• What it the location of Hengistbury Head? What is H.H. like…?• What are geomorphic processes?• What geomorphic processes are occurring at H.H.?• How are geomorphic processes changing the landscape?• What landforms are these geomorphic processes creating?• How are people/environment affected? (positive/negative)• Is there any evidence of coastal management to reduce the impact of geomorphic processes?
  23. 23. Prep for the intro: the location Where is Hengistbury Head? What is the location like?
  24. 24. Location maps• Essential skill• Key way to pick up marks – not included in word limitTask:• Annotate the O.S. map & satellite image of H.H. to show features, landforms, management, land use, etc.• What map evidence is there of geomorphic processes? (e.g. landforms? Management?)

It is mainly used for beach huts as seen in Photo A. The spit is important for tourism. Photo A
  26. 26. Useful linksIn terms of secondary data:• Geology: http://www.hengistburyhead.org/nature/geology.html• Geology http://www.southampton.ac.uk/~imw/Hengistbury-Head-Geology.htm• Lots of useful stuff here: http://www.scopac.org.uk/• A newspaper article giving some good context on the effect of geomorphic processes: http://www.bournemouthecho.co.uk/news/4542643.___Hengistbury_Head_could _disappear__over_next_century___/• And the excellent Hengistbury Head website - http://www.hengistbury- head.co.uk/index.html• Google Earth – use the history bar and track changes over timeIn terms of skills:• BBC Bitesize now has a handy CA section: http://www.bbc.co.uk/schools/gcsebitesize/geography/geographical_skills/• The FSC has some handy how to guides available here: http://www.geography- fieldwork.org/coastfieldwork/index.htm ; including pebbble roundness and beach profiles http://www.geography- fieldwork.org/coastfieldwork/coastal_management/stage2.htm
