2. When does deposition occur?

  • When the river loses velocity and energy
  • When the river gains velocity and energy
  • When the river gains velocity and loses energy
  • When the river loses velocity and gains energy

3. What are the methods of transportation?

  • Suspension, traction, hydraulic action, saltation
  • Hydraulic action, abrasion, attrition, solution
  • Traction, suspension, saltation, solution
  • Traction, attrition, saltation, abrasion

4. What is hydraulic action?

  • The force of the river water colliding with rocks breaks rock particles away from the river channel.
  • Eroded rocks picked up by the river scrape and rub against the channel wearing it away.
  • Eroded rock picked up by the river crash into each other and break into smaller fragments. Their edges also get rounded off as they rub together. The further material travels, the more it is eroded - causes particle size to decrease from the river's source to its mouth.
  • River water dissolves some types of rock, e.g. chalk and limestone.
