Coasts: erosion, deposition and management
Learn Coasts: erosion, deposition and management for Years 7–9 pupils (ages 11–14). Free practice questions, lessons and worked examples — aligned to the UK National Curriculum.
What you'll learn
- 1
Destructive waves erode the coast; constructive waves build it up by depositing material.
- 2
A headland erodes in sequence: crack → cave → arch → stack → stump.
- 3
What forms when the roof of an arch collapses?
- 4
Longshore drift moves material along the coast in a zigzag, driven by waves arriving at an angle.
- 5
Hard engineering (sea walls, groynes) resists the sea directly but is costly and can worsen erosion further along. Soft engineering (beach nourishment, managed retreat) works with natural processes.
- 6
Which is an example of hard engineering?
- 7
Why can coastal defences cause problems elsewhere?
