How did Old Harry end up alone? Monday, 20 May 2019 How did Old Harry end up alone? To know how geology affects coastal configuration To be able to explain the formation of erosion landforms

What are these landforms called? Monday, 20 May 2019 What is a landform? A landform is a feature of the landscape that has been formed or sculpted by processes of erosion, transportation or deposition. What are these landforms called?

Monday, 20 May 2019 Headlands and Bays Geology is responsible for shaping the coast- what does geology mean? Match the cards to the diagram Different rock types are eroded at different rates. The softer rocks are eroded by hydraulic action much faster rate causing the cliff to retreat The weaker areas erode forming crescent shaped bays where deposition takes place forming sandy beaches Some rocks on the coast are tougher and more resistant than others for example chalk, sandstone and granite are hard and clay is much weaker. The hard rock erodes much slower and is left sticking out to sea. These are high energy environments and form headlands.

Depositional Landforms Monday, 20 May 2019 Starter: Mix and Match Erosional Landforms Depositional Landforms Headlands Wave-cut platforms You will have to think carefully about if we have studied them yet or not and why that may be a clue… Bays Cliffs Sand dunes Beaches Bars Arches Caves Spits Stumps Stacks

How do cliffs and wave-cut platforms form? Monday, 20 May 2019 How do cliffs and wave-cut platforms form? To know how geology affects coastal configuration To be able to explain the formation of erosion landforms

What are wave-cut platforms? Monday, 20 May 2019 What are wave-cut platforms?

Development of Wave Cut Platforms

High Tide Low Tide 1 Abrasion occurs between high and low tide- rocks are hurled at the base of the cliff.

2 Cliff is undercut, leaving it unstable. Wave Cut Notch Eroded material available to take part in abrasion. 2

3 Cliff retreats Wave Cut Notch The process of abrasion will continue… Wave Cut Platform- abrasion can not occur below low tide. 3

Cliff retreats Wave Cut Platform. 4

Dissipation of wave energy Task Using the terms below, produce a four picture storyboard on the table explaining the process that produces a wave cut platform. Abrasion High Tide Low Tide Dissipation of wave energy Collapse Wave Cut Notch Retreat Cliff Wave cut platform Wide and flat

BUG this question… A feature formed by erosion, deposition or transportation “Use one distinctive coastal landform to illustrate the erosive power of the sea” [6 marks] Which landforms can we talk about? Must be marine erioson not sub-aerial processes Explain how something has happened I should only spend 6 minutes on this question.

Plenary: Peer assess Tell them something that they did well When peer assessing, you should TAG: Tell them something that they did well E.g. I really liked the way you sequenced your explanation Ask them a question E.g. Have you tried explaining the processes involved? Give an example E.g. ‘The water erodes between the high water mark and low water mark by abrasion. This is when…
