  • Erosion
    • Hydraulic Action
      • The force of the water breaks rock particles away from the river channel
    • 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
    • Abrasion
      • Eroded rocks picked up by the river scrape and rub against the channel, wearing it away
      • Most erosion happens by abrasion
    • Solution
      • Water dissolves some types of rock
      • eg. chalk and limestone
