- coasts and rivers
- weathering
- mechanical
- break up with no chemical change
- e.g. freeze-thaw
- break up with no chemical change
- chemical
- dissolving rock
- acidic rain/ sea water
- dissolving rock
- biological
- e.g. roots growing in rock
- mechanical
- mass movement
- rockfall
- bits of rock fall off cliff-face; usually due to free-thaw weather ing
- slides
- large blocks of rock slide downhill
- mudflows
- saturated soil flows down slope
- rotational slip
- saturated soil slumps does curved surface
- rockfall
- casual erosion
- abrasion
- pebbles grind along a rock platform or cliff base e.g. sandpaper. this rock eventually becomes smooth
- attrition
- rocks hit each other rand break
- solution
- seawater dissolves cliffs
- hydraulic action
- air in cracks compressed by waves
- abrasion
- transpiration
- solution
- dissolved salts and materials
- suspension
- finer material suspended by waves
- salutation
- pebbles bounced
- traction
- heavier rocks rolled
- solution
- weathering
