Coastal Landforms caused by erosion Coastal Landforms are either ‘depositional’ landforms or ‘erosional’ ones. We will look at ‘erosional’ ones first We will cover: 1. Bays and headlands 2. Wave cut platforms 3. Caves, arches and stacks
Headlands Picture the scene…. You are 6 yo and making sandcastles on a small beach…. You get a bit bored and decide to go for a walk … should you go to the cliffs on the left or the cliffs on the right? and bays. http: //www. flickr. com/photos/anthonythomas/3085961629/
Harder rock Softer rock Harder rock Waves attack the coastline.
This area is now more Harder sheltered, this rock Harder rock encourages deposition and beaches are formed. Softer rock Harder rock The softer rock is eroded by the seaforming a bay. The more resistant rock is left sticking out into the sea called a headland.
Harder rock Softer rock Harder rock Surrounded by deep water and exposed to the full force of the waves- the headlands are eroded. The shallower waters in the bay continue to encourage deposition.
Headlands and Bays- Scarborough
Work to help you learn Bays and Headlands Look at Wider World page 238 …. . A typical exam question might read “With the aid of a diagram explain how bays and headlands are made. (4 marks) A* grade Challenge: Include detail, linkages, key words and an example Also notice how the text book version is simpler than the diagrams I have shown you. I also mentioned how “shallower waters can lead to more deposition because the waves will have less energy” and how the headlands are more open to the wind and therefore erosion …. .
