  1. Pop-up headland.. http://www.flickr.com/photos/sacherfire/217113480/

  2. 1 You need your template. This will represent a chalk headland.

  3. 2 Using a blue crayon- shade the outside horizontal strips- these represent the sea.

  4. 3 Using a green crayon- shade the middle horizontal strip- this represents the top of the headland- exposed to weathering.

  5. 4 Just above the horizontal blue lines- shade a grey line- make sure it reaches the top of the wave-cut notch. This represents wave action between high and low tide.

  6. 5 Don’t cut off your stump! Carefully cut out all the black areas on the template- with the exception of the wave-cut notch.

  7. 6 It should look like this...

  8. 7 Using a ruler, carefully fold the horizontal lines.

  9. 8 Like this...

  10. 9 Glue along the two blue horizontal strips- on the reverse!

  11. 10 Position the green strip over the centre of your book. Gently glue down the blue horizontal strip- the one with the stump.- Practice your positioning first.

  12. 11 Carefully practice folding the model... are the folds the right way?

  13. 12 Finally, glue the final blue strip down. Practice the positioning first...

  14. 13 Gently close your book...

  15. 14 Magic...

  16. 4 5 1 3 2 6 Arty shot...

  17. About the template... You could draw your own template or print this slide and use for the model. The template should be A5 to fit into across a A4 exercise book- of course you could supersize the model.

  18. Use the following labels to annotate your pop-up headland model. Use the following labels to annotate your pop-up headland model. This is a chalk headland. Chalk is a sedimentary rock; therefore there are many lines of weakness running through the headland. Hydraulic action will exploit these cracks, widening them over time. This is a chalk headland. Chalk is a sedimentary rock; therefore there are many lines of weakness running through the headland. Hydraulic action will exploit these cracks, widening them over time. Continued corrasion will widen and deepen the wave cut notch into a cave. Continued corrasion will widen and deepen the wave cut notch into a cave. The base of the stack will be continually attacked by the sea- over time it may become unstable, it will collapse to form a stump. The base of the stack will be continually attacked by the sea- over time it may become unstable, it will collapse to form a stump. When two caves are formed either side of the headland, over time they may erode backwards and meet, forming an arch. When two caves are formed either side of the headland, over time they may erode backwards and meet, forming an arch. Corrasion hurls rocks at the base of the headland, between high and low tide. This undercuts the cliff creating a wave cut notch. Corrasion hurls rocks at the base of the headland, between high and low tide. This undercuts the cliff creating a wave cut notch. Continued erosion at the base of the arch will make it unstable. The roof will collapse into the sea, forming a stack. Continued erosion at the base of the arch will make it unstable.
