Across
  1. 3. (LOWER COURSE) as floodplains are so flat, they are often built on, which is a problem as these areas have high __-__.
  2. 4. Lateral erosion increases the width of the river and valley, eroding __
  3. 7. (UPPER COURSE) lateral erosion is caused due to __ acting on the steep gradient.
  4. 9. (UPPER COURSE) the upper course of a river has a __ gradient
  5. 13. River deposition can happen when there is less __ from a lack of precipitation
  6. 14. (UPPER COURSE) waterfalls and rapids also form here in the upper course because of __ erosion.
  7. 15. (LOWER COURSE) floodplains soak up water during the event of a __.
  8. 18. A channel is formed as a river cuts a path through __.
  9. 20. (UPPER COURSE) v-shaped valleys are found here, where __ gather in the upper course
  10. 21. (MIDDLE COURSE) the middle course of a river has a __ gradient
  11. 22. (LOWER COURSE) floodplains can be found within the lower course as they are flat pieces of land either side of a __
  12. 24. (LOWER COURSE) the lower course of a river has a __ gradient
  13. 25. Vertical erosion is dominant in the __ course of rivers
  14. 26. (MIDDLE COURSE) the middle course’s cross section would be deeper, with __ channels
Down
  1. 1. (LOWER COURSE) the cross-profile of a river’s low course has a deep, __ channel with flat, __ floodplains.
  2. 2. (LOWER COURSE) estuaries often contain __
  3. 5. (LOWER COURSE) estuaries are also found in the lower course, which are natural __ zones where freshwater meets the salty sea.
  4. 6. River deposition can happen when the river enters the __/lake
  5. 8. River discharge is the __ of water flowing through a river channel at a specific point.
  6. 10. (UPPER COURSE) v-shaped valley’s cross-sections have n__ c__ and steep sides.
  7. 11. (MIDDLE COURSE) __ can form in the middle course and leave an ox-bow lake.
  8. 12. River long profiles are used to show us the change in __ from the river’s source to the mouth.
  9. 16. Vertical erosion happens more dominantly in the upper course due to the high __ of the water driving rough, jagged particles along the river bed.
  10. 17. (MIDDLE COURSE) meanders and ox-bow lakes are created due to __ erosion in the middle course
  11. 18. Lateral erosion is dominant in the middle and __ course of rivers
  12. 19. River deposition can happen when the river gradient __ because it requires more energy to transport material.
  13. 23. Vertical erosion increases the __ of a river and valley, eroding downwards
