  • Erosion, transportation, deposition
    • Erosion is the wearing away and removal of material
      • hydraulic action
      • abrasion
      • attrition
    • Deposition when a river drops the eroded material it is carrying
      • It happens when a river loses velocity - why?
        • the volume of water in the river falls
        • the amount of material in the river increases
        • the river is shallower e.g. on a bend
        • the river reaches its mouth
  • traction
    • Transportation is the movement of eroded material
      • Saltation
      • suspension
      • solution
