- Erosion
- Rivers
- When a river wears away rocks from their bed and their banks
- The material is carried downstream and deposited when the water slows down

- Ice
- A glacier is a tongue of ice moving down a valley
- Stones and boulders fall onto it and freeze
- It acts as sandpaper to the rocks beneath it
- the glacier carries the materials downwards and at the same time wears away the valley bottom and sides

- Sea
- coastline are under constant attack by waves
- when the waves repeatedly hit the rock with a lot of weight, the rock is weakened
- pieces then break off
- the current carry loose material away and deposit it elsewhere
- pieces then break off
- Wind
- The wind picks up tiny particles of sand
- It is blasted into anything that is in the way
- desert rocks are often eroded into strange shapes by this sandblasting effect
