All of these landforms are mainly formed by erosional processes:
Headlands and Bays
Cliffs and Wave-Cut Platforms
- 1. Waves breaking against a cliff will create a notch at the high-tide mark through corrasion and hydraulic power.
- 2. Over hundreds of years the notch will grow deeper into the cliff face. Eventually the notch will have removed so much material the cliff cannot support its own weight and will collapse.
- 3. This process will repeat over time as the cliff retreats. A rocky platform will be left behind called a wave-cut platform.
- 4. A cliff and wave-cut platform are formed. The wave-cut platform will be smooth in most places due to abrasion. Some areas will be scarred and have created rockpools.
Caves, Arches and Stacks
This is happening on a headland as shown in the first erosional process.
Bare in mind that you won't see this diagram as this in reality. This is a model that shows what happens as erosion keeps acting on a headland. There will be a collection of different landforms along any given headland.
