Landforms of Erosion
Landforms of Erosion
This page develops a number of activities, including photograph analysis, animations, diagrams to have students investigate wave action and the resulting landforms. Students look in detail at cliffs and wave-cut platforms, types of coasts of erosion, including concordant and discordant coasts, resulting headlands and bays and then wave refraction and stack formation. It uses a number of examples such the Twelve Apostles, Australia, the Moher cliffs, Ireland and the Jurrassic coast, England. There is a particular focus on sequencing including an in-depth photograph annotation assessment.
How do waves create coastal landforms of erosion?
Starter Activity - Wave Cut Platforms - Processes
Study the following image and discuss how the cliff formed
Student Activity - Wave-cut platforms Map from Memory - Processes
Study the diagram for 30 seconds and then attempt to replicate it in your books. Alternatively students can work in group and they come up to see the image from the teacher's computer and then report back to their group who then based on the instruction of the their team mate need to replicate the diagram. Repeat several times.
Once complete students should make a drawn sketch of their own
What factors are most important when explaining the formation of wave-cut platforms?
How can we incorporate:
Student Activity - Headlands and Bays - Processes
Study the following photograph of the Cliffs of Moher in Ireland
- Describe the coastline and its characteristics
- Attempt to suggest reasons for it
Student Activity - Coasts of Erosion - Processes
Study the two images below and suggest reasons for the characteristics of the coastlines shown
Student Activity - Wave Refraction and Headland Erosion - Processes
Study the following animations sequence
Click the image and follow the slides - What causes wave refraction and how is it likely to effect the erosion of a headland
Watch the following video of the 12 Apostles in Australia, showing unique footage of before and after headland and stack collapse
Watch the following video of plasticine headland being eroded
Make your owe video of a headland being eroded. Remember the basics of location, sequence and technical vocabulary
Student Assessment: Annotation exercise - Processes and Places
Study the following photograph and annotate it to explain all the processes and landforms present
