1. Transportation and deposition
Starter: Activities on next few slides to recap ‘erosion’
Transportation and deposition
Objective: To describe and explain the landforms created by transportation and deposition

2. Swanage Bay An example of headlands and bays on the Dorset coastline.
Objective: To describe and explain the landforms created by transportation and deposition

3. Headlands and bays
Objective: To describe and explain the landforms created by transportation and deposition

4. If these photos were taken of one headland over time, which of these landforms would be the first to be formed?
Objective: To describe and explain the landforms created by transportation and deposition

5. Learning objectives How do waves operate?
What are sub-aerial processes and why are they important?
What processes of erosion operate at the coast?
What landforms are created by erosion?
What processes of transport operate at the coast?
What landforms are created by deposition?
Learning objectives
Objective: To describe and explain the landforms created by transportation and deposition

6. How is sediment transported along the coast?
Objective: To describe and explain the landforms created by transportation and deposition

7. Longshore drift Direction of movement
Backwash is always at right angles to the beach
swash
Backwash
This movement of sediment along the coastline is called longshore drift.
Objective: To describe and explain the landforms created by transportation and deposition

8. Examination question Study the photograph of Swanage Beach.
Level 4
I say what longshore drift is
Level 5
I explain how long shore drift works.
Level 6
I explain in detail how longshore drift works.
Level 7
I use examples from the Dorset coast to explain how longshore drift works
What is longshore drift?
Add an arrow to the photo to show which direction longshore drift is operating in.
Draw your own diagram to explain how longshore drift operates.
Objective: To describe and explain the landforms created by transportation and deposition

9. Learning objectives How do waves operate?
What are sub-aerial processes and why are they important?
What processes of erosion operate at the coast?
What landforms are created by erosion?
What processes of transport operate at the coast?
What landforms are created by deposition?
Learning objectives
Objective: To describe and explain the landforms created by transportation and deposition

10. Landforms of coastal deposition
Beaches
Spits
Tombolos and Bars
Objective: To describe and explain the landforms created by transportation and deposition

11. How are beaches formed?
Beaches form in sheltered environments, such as bays. When the swash is stronger than the backwash, deposition occurs.
Sometimes sand from offshore bars can be blown onto the shore by strong winds.
In such cases dunes may form – such as at Studland on the Dorset Coast.
Objective: To describe and explain the landforms created by transportation and deposition

12. How are spits formed?
Objective: To describe and explain the landforms created by transportation and deposition

13. How are spits formed?
Objective: To describe and explain the landforms created by transportation and deposition

14. How are spits formed?

15. How are spits formed? (use diagram to help you)
Level 4
I say what a spit is
Level 5
I explain how a spit is formed.
Level 6
I explain in detail how a spit is formed.
Level 7
I use examples from the Dorset coast to explain how a spit is formed.
Objective: To describe and explain the landforms created by transportation and deposition

16. Coastal landforms in Studland
Drag and drop exercise.
Objective: To describe and explain the landforms created by transportation and deposition

17. Erosion or deposition?
Objective: To describe and explain the landforms created by transportation and deposition

18. Key Ideas
Waves are the result of the wind blowing over the sea. They break as they approach land.
Swash and backwash describe the movement of a wave on the beach. Fetch is the distance that the wind has travelled.
Sub-aerial processes such as weathering and mass movement occur on the cliff face.
Coastal processes of erosion include hydraulic action, attrition, corrosion and solution.
Landforms created by erosion include headlands and bays, caves, arches, stacks and stumps.
Longshore drift is a method of coastal transport.
Landforms created by deposition include beaches, spits, tombolos and bars.
