Across
  1. 6. The transport of fine sediment carried and floating within the water.
  2. 7. The starting point of a river, usually in upland areas.
  3. 8. A steep-sided, narrow valley formed by river erosion when a waterfall has retreated upstream.
  4. 9. The process of rocks colliding and breaking into smaller, smoother, rounder pieces.
  5. 11. Erosion caused by the dissolving of soluble minerals in water.
  6. 12. A circular hole in the riverbed formed by drilling of rocks and erosion.
  7. 13. The force of water and air entering cracks in the riverbanks, eroding them via mini explosions.
  8. 15. The dropping of sediment when a river loses energy or sediment is too big to carry.
  9. 17. A vertical drop in a river’s course where resistant rock lies over the top of soft rock.
  10. 18. Rock projections of high land that alternate on either side of a valley.
  11. 21. The boundary separating one drainage basin from another.
  12. 23. The flat area of land on either side of a river prone to flooding.
  13. 24. The shallowest water in the river. It is the opposite of a river pool.
  14. 25. The material deposited on a floodplain that makes it really fertile.
Down
  1. 1. pool A deep pool formed at the base of a waterfall due to hydraulic action and abrasion.
  2. 2. Erosion caused by rocks and sediment eroding against the riverbed and banks like sandpaper.
  3. 3. The gently sloping bank found on the inside of a meander due to deposition.
  4. 4. Downward erosion of a river channel.
  5. 5. Energy possessed by water due to its elevation above sea level. This is why there is lots of vertical erosion in the upper course.
  6. 10. The point where two rivers meet.
  7. 14. The area of land drained by a river and its tributaries.
  8. 16. The process where small pebbles bounce along the riverbed.
  9. 19. The corkscrew motion where water bounces off the outside bends and meanders.
  10. 20. Erosion that widens a river channel or valley.
  11. 22. A landform at the river mouth where sediment is deposited.
