Across
  1. 4. river embankments built by deposition as the river floods
  2. 5. material bounced along the bed of the river
  3. 6. the highland separating one river basin from another.
  4. 8. the land that is drained by a river and its tributaries
  5. 9. form where the river meets a band of softer rock after flowing over an area of more resistant material. Waterfalls progressively cut back, leaving a gorge.
  6. 13. the point at which rivers meet.
  7. 15. where a river ends, at a lake or the sea.
  8. 18. the speed of the water flow.
  9. 19. the cross-section of the river, from its source to its mouth, concave in shape.
  10. 20. finger-like river channels which branch away from a main river channel in a delta
  11. 23. found where the river meets a band of resistant rock and usually precede a waterfall.
  12. 24. a smaller river that joins a larger one.
  13. 25. The sheer force of the water by itself can erode material from the bed and banks of the river channel
  14. 26. also known as Slip-Off Slope.
  15. 27. Holes: holes eroded in the solid rock of a river channel. They are drilled by pebbles caught in eddies in the river.
Down
  1. 1. a bend in a river. The outside of the meander has the fastest flow and deepest water
  2. 2. created on the outside of a meander bend by the erosive effect of fast-flowing water
  3. 3. Valley: a deep v-shaped valley is usually found in the upper course of the river where the water has considerable erosive power.
  4. 7. the amount of water passing a specific point at a given time
  5. 10. the pebbles being transported wear away the bed and banks of the river channel.
  6. 11. the wide, flat floor of a river valley.
  7. 12. some rocks such as limestone are subject to chemical attack and slowly dissolve in the water.
  8. 14. Course: the mountain stage of a river with steep gradients and much erosion.
  9. 16. Lake a meander which has been cut off from the main river channel and abandoned
  10. 17. the material carried by a river by being bounced or rolled along its bed.
  11. 21. The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size.
  12. 22. the break-down or decomposition of rock by biological, physical or chemical processes.
  13. 26. the deep pool below a waterfall.
