• What are the three main processes involved in the movement of earth by rivers?

  Erosion, transportation, and deposition
• How do rivers contribute to erosion?

  Rivers erode and pick up earth from their surroundings
• What happens to the earth that rivers pick up?

  They dump it when they find somewhere new to go
• What are the four processes of erosion by rivers?

  1. Hydraulic action
  2. Abrasion
  3. Attrition
  4. (Missing information)
• What is hydraulic action in the context of river erosion?

  It is the force of river water colliding with rocks that breaks rock particles away from the river channel
• How does abrasion contribute to river erosion?

  Abrasion occurs when eroded rock is picked up by the river and rubs against the channel, wearing it down
• What is attrition in the context of river erosion?

  Attrition is when eroded rock particles crash into each other and break into smaller pieces
• What happens to the edges of rock particles during attrition?

  The edges get rounded off as they rub together
• What are the effects of hydraulic action, abrasion, and attrition on river erosion?

  • Hydraulic action breaks rock particles away from the river channel
  • Abrasion wears down the river channel by rubbing eroded rock against it
  • Attrition breaks rock particles into smaller pieces and rounds their edges
