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

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

8. Objective: To describe and explain the landforms created by
transportation and deposition
Examination question
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.
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

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

11. Objective: To describe and explain the landforms created by
transportation and deposition
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.

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

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

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

15. Objective: To describe and explain the landforms created by
transportation and deposition
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.

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

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

18. Objective: To describe and explain the landforms created by
transportation and deposition
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.
