1. Controlled Assessment Task 1 Due: 28 th June Fieldwork Focus : Coastal Management

4. How many of these coastal landforms can you spot? ARCH STACK CAVE WAVE CUT PLATFORM STUMP CLIFF WAVE CUT NOTCH COLLAPSED ARCH BAY HEADLAND SPIT

5. Types of coastal erosion

8. The main landforms created by erosion are…

9. Headlands and Bays

11. Wave cut notches and platforms

12. Wave erosion is greatest when waves break against the foot of the cliff. With wave energy at a maximum, the waves undercut the foot of the cliff to form a wave cut notch Over time the notch enlarges and the cliff above it cannot be supported and so collapses As this is repeated, the cliff retreats (and often increases in height). The gently sloping expanse of cliff marking the foot of the retreating cliff is known as the Wave cut platform

13. Does this remind you of anything? Waterfalls and gorges – very similar ideas!

15. Wave-cut platform –Burgh Island, Devon Wave cut platform Southerndown, South Wales.

16. Caves Arches Stacks and Stumps

18. How was the arch at Durdle Door, Dorset, formed? Abrasion/Corrasion Hydraulic action Solution/Corrosion Attrition

20. 1. The waves erode FAULTS (cracks) in the headland. 2. The waves eventually erode through the headland to form an ARCH . 3. The arch becomes unsupported and collapses to form a STACK . 4. A STUMP is formed from the collapsed stack. C D B A Match the image with the most appropriate label.

22. What about waves?

23. If you were a wave, and you wanted to grow big and strong so you could knock the UK’s block off, which direction would you come from? Why?

26. How do waves influence erosion? Longshore drift

27. Long-shore drift (LSD)

31. So, the controlled assessment How does it work?

33. Example checklist

34. What does the markscheme look like? How will you be marked?
