- water evaporates leaving salt crystals

- these create cracks in rocks and they break away

What is a wave cut platform?
A
- Point of erosion at the bottom of a cliff from waves
- Sloping rocky area left by continual wave erosion and cliff collapse.
5
Q
THREE ways in which change in climate can affect cliff retreat
A
- Increased wave energy in extreme weather conditions/ storms
- Increased rain fall - destabilising cliffs
- Freeze/thaw cycles.
6
Q
Concordant coastline?
Discordant coastline?
A
- Different rock types (resistant and less resistant) run parallel to the coastline
