  • Erosion
    • Attrition
      • Eroded rocks picked up by the river smash into each other, and break into smaller fragments.
      • Their edges also get rounded off as they rub together.
    • Hydraulic action
      • The force of the water breaks rock particles away from the river channel
    • Corrasion
      • Eroded rocks picked up by the river scrape and rub against the channel, wearing it away.
      • Most erosion happens by Corrasion.
    • Corrosion
      • River water dissolves some types of rock, e.g. Chalk and Limestone.
