- WEATHERING
- Physical
- Freeze-Thaw Action
- Rainwater enters crack on cliff face
- At night, temperature drops and water freezes and expands, making the crack bigger
- During the day, the ice melts and more water is added to the larger gap
- Process repeats until the rock fall off

- Salt Crystal Growth
- Sea water left on rock
- Water evaporates, leaving salt behind
- Salt crystals grow and exert pressure on rock
