COASTAL LANDSCAPES 3: "Say hello, wave goodbye"

Powerpoint looking at erosion and transportation along Holderness

Starter: the properties of powerful waves, including fetch

Main activities: map work to measure the fetch from Holderness to various coasts of the North Sea. Then radar diagrams are introduced, using a wind rose as an example followed by the pupils constructing a radar to show dominant wave patterns. Then the link between the UK's SW prevailing wind and how it causes NNE dominant waves. Differentiated question... 1-3: What makes a sea wave powerful? 4-6: Explain why North Sea waves can be powerful and damaging
7-9: Refer to data which suggests that Holderness is threatened by powerful waves

Second part gets pupils to draw and label diagrams to compare the features of constructive and destructive waves. They are then asked to assess photos of Holderness to decide which type of wave is affecting that coastline.

Third part looks at the properties of boulder clay and why that soft geology is a problem. Differentiated question: 1-3: Why are the caravan owners worried about the erosion of the cliffs at Hornsea? 4-6: Explain why erosion of the boulder clay is a problem for Holderness
7-9: Explain why the erosion of boulder clay is an economic problem for Holderness businesses

Plenary: pupils are asked to show how they think a typical wave moves, then are shown an animation that describes the circular motion of real wave patterns
