1. Spurn Head What is this and what might have caused it?

2. Here is one clue

3. Here is another clue

5. Spurn Head is located on the Humber Estuary on the East Yorkshire Coast. It has a classical shape with a hooked end. How long and how wide? Why doesn’t it grow over the estuary? How did it come to be?

6. Erosion of Boulder Clay on the Holderness section of the coast

7. When is and isn’t it eroding?

8. Sediment in the sea

9. Longshore drift Longshore drift is the movement of material along the beach in a zig zag pattern. The swash approaches at an angle to the beach pushing the sediment with it. The backwash pulled by gravity drags the beach material back into the sea where the process repeats.

10. Evidence from groynes

11. Creation of Spurn Head For a spit to be created there needs to be longshore drift occurring plus; there needs to be shallow and sheltered water and lastly a change in the shape in the coast line

12. Has it always been a spit? Spurn Head is cyclic which means that it goes through a 250 years of creation and destruction. But people have built homes along the coast which means it will need protection from erosion.

13. How do we protect? Spurn head is cyclic which means that it goes through a 250 years of creation and destruction. But people have built homes along the coast which means it will need protection from erosion.

14. This is also a form of protection it is a concrete wall which should stop wave damage but is it effective? ‘Hard’ approaches

15. How do we protect? What other protection could be used? ‘Softer’ approaches

16. Protect one place erode another

17. Summary The main features of deposition are is a very long spit the most noticeable is Spurn Head on the Holderness Coast.

18. Make a sketch Draw a location and sketch map of Spurn Head and explain how it was formed - a storyboard is a good way of doing it.
