  • Hydraulic Action, Solution, Saltation and Attrition
  • Hydraulic Action, Corrosion, Attrition and Abrasion
  • Hydraulic Action, Levees, Solution and Attrition

7. When does a waterfall form?

  • When an area of hard rock is next to and above an area of soft rock with a river flowing across it
  • When a wave-cut platform is above a cave
  • When an area of soft rock is next to and above an area of soft rock with a river flowing across it

8. What are the two human factors of flooding?

  • Waterfalls and Deforestation
  • Deforestation and Buildings
  • Meanders and Snowmelt

9. Which of the options are present when a river drops its load?

  • Water is deeper
  • Volume of water in the river falls
  • Volume of eroded material decreases

10. Which of these are both physical factors of flooding?

  • Buildings and Prolonged Rainfall
  • Snowmelt and Heavy Rainfall
  • Prolonged Rainfall and Deforestation

11. What is Attrition?

  • A type of Mechanical Weathering
  • Rocks tap against eachother making angular rocks become smooth
  • Rivers pick up stones and use them erode the sides of the valley

  • Steep Gradient with a V-Shaped, steep sided valley. Narrow and shallow channel.
  • Medium Gradient with a U-Shaped, sloping sided valley. Wide but shallow channel.

16. What does a 'Cross Section' of a river show?

  • The height of the river bed at different points in the river
  • Cross section at ONE POINT in the river
  • Number of meanders along the river

17. Which of the options are NOT evidence for waterfalls on a map?

  • Close contour lines

18. What does a 'Long Profile' of a river shows?

  • Gradient changes over the different courses of a river
  • Length, in metres, of different rivers compared to eachother
  • Number of meanders along the river

19. What is the 'Lag Time' on a Hydrograph

  • Delay between peak rainfall and peak discharge
  • Increase in rivers discharge in one hour
  • Height of rainfall vs. Height in river
