1. How can cliff collapse
cause problems for
people at the coast?

2. Look at this geology map of Britain
•
We are looking for places that
you think will be the most
vulnerable to cliff collapses?
•
What makes a coastline more
vulnerable to erosion?
•
Locate Barton-on-Sea using
the textbook as a guide.
These rocks are weaker
and more easily eroded.

4. What is a cliff collapse?
• An element of coastal erosion
• Why are we studying it?
– The effect that it can have on people (when
people live very close to the coastal zone)
– The effect on the environment
A cliff collapse – how far do you think the cliff has lowered in this photograph?

5. What makes Barton-on-Sea so
vulnerable to cliff collapses?
• Geology (as we have already
demonstrated)
• Sand overlays clay in places
• Sand is permeable, clay is impermeable.
• How does this create problems?
• Fetch? (can we remember what this is?)
• Housing built close to the cliff
• Problems for residents?
• Interference with drainage

6. Why is the arrangement of the geology at
Barton-Sea so important?
How would you draw diagrams 3 & 4?
Draw a diagram for 6th June 2008 (3.) and January 2009 (4.)

11. Reminder...some of the factors
that can influence cliff collapse?

Can you think
of any others?
