How are headands like this formed?
Headlands and Bays
Headlands and bays are formed when the sea erodes rocks at faster and slower rates.
What features form when headlands are eroded?
Task 1
- Cut out and arrange the photos of the headland erosion in the correct order.
- Stick them on paper, or in your book.
- EXT – Can you add some annotations that explain what is happening?
Task 2
Complete the worksheet to explain the development of caves and stacks.
Extension
What factors will increase or decrease the rate of erosion of the Headland?
Can you name and locate any other eroded headlands, stacks, and stumps?
Stack Formation
Have a look at this great video from Time for Geography that explains the process.
Durdle Door Case Study
Use the video below to see how erosion processes have contributed to the development of Durdle Door.

Why does sand move down the beach?
Longshore Drift
The prevailing wind causes the direction of the waves.
The waves approach the beach at an angle.
This is called Swash.
The waves retreat perpendicular to the coast bac out to sea.
This is called backwash
Over time the Zig-Zag effect of the waves causes material to move down the coast line.
