- Coastal Landforms caused by Erosion
- Wave Cut Platforms
- erosion happens at the foot of the cliff to form a wave cut notch
- the notch becomes unstable and eventually collapses
- collapsed material is washed away and the process happens again
- Repeated process leads to a retreating cliff and a wave cut platform left behind
- collapsed material is washed away and the process happens again
- the notch becomes unstable and eventually collapses
- erosion happens at the foot of the cliff to form a wave cut notch
- Headlands and Bays
- Some rock types are more resistant to erosion than others
- headlands and bays from where erosion resistance alternating
- Bays form when the less resistant rock erodes quickly forming a gentle slope
- The resistant rock erodes more slowly and is left jutting out forming a headland
- Bays form when the less resistant rock erodes quickly forming a gentle slope
- headlands and bays from where erosion resistance alternating
- Some rock types are more resistant to erosion than others
- Caves, Arches and Stacks
- Headlands have weaknesses that when are eroded form cracks
- repeated erosion of hydraulic power and abrasion enlarge the cracks forming caves
- continued erosion deepens the cave until it breaks through the headland forming an arch
- erosion continues to wear away the rock supporting the arch until in eventually collapses forming a stack
- continued erosion deepens the cave until it breaks through the headland forming an arch
- repeated erosion of hydraulic power and abrasion enlarge the cracks forming caves
- Headlands have weaknesses that when are eroded form cracks
- Wave Cut Platforms
