The 20 questions

  1. What is the starting point of a river called?

    • Source
    • Mouth
    • Confluence
    • Tributary

  2. What is the end point where a river meets the sea called?

    • Estuary
    • Mouth
    • Source
    • Watershed

  3. What type of graph shows a river's height from source to mouth?

    • Cross profile
    • Long profile
    • Bar chart
    • Pie chart

  4. On a long profile graph, what does the vertical axis show?

    • Velocity
    • Distance
    • Width
    • Height

  5. On a long profile graph, where is the river's source located?

    • Right-hand end
    • Left-hand end
    • Middle
    • Top

  6. What does a steep river gradient indicate about the land?

    • Widens rapidly
    • Rises slowly
    • Drops quickly
    • Stays flat

  7. What is a smaller stream that flows into a larger river called?

    • Estuary
    • Tributary
    • Distributary
    • Delta

  8. Where along its course is a river's gradient usually steepest?

    • In the middle
    • At the estuary
    • Near the source
    • Near the mouth

  9. On a long profile, what does a flat section near the right-hand end show?

    • Steep gradient
    • High mountain
    • Gentle gradient
    • Fast waterfall

  10. In which direction does a river always flow?

    • Downhill
    • Southwards
    • Uphill
    • Northwards

  11. Where is a river channel typically at its widest?

    • At a waterfall
    • In the mountains
    • At the mouth
    • At the source

  12. Why does a river usually get wider as it flows downstream?

    • Rain stops falling
    • Evaporation increases
    • Tributaries add water
    • Gradient gets steeper

  13. What change typically happens to a river as it flows downstream?

    • Becomes wider
    • Speeds up constantly
    • Loses all water
    • Becomes narrower

  14. What is the typical channel shape near a river's source?

    • Narrow and steep
    • Deep and slow
    • Wide and tidal
    • Wide and flat

  15. Which river feature is found in the lower course near the mouth?

    • Waterfall
    • Rapids
    • Gentle gradient
    • V-shaped valley

  16. Why does a river become wider and deeper as it approaches its mouth?

    • Water evaporates
    • Rain stops falling
    • Land gets steeper
    • Tributaries join

  17. Which part of a river's long profile is steepest and located near the start?

    • River mouth
    • Upper course
    • Middle course
    • Lower course

  18. What causes a river to carry a much larger volume of water in its lower course?

    • Faster evaporation
    • Narrower channels
    • Tributaries joining
    • Increased friction

  19. How does a river with a very steep upland section appear on a long profile graph?

    • Curves upwards
    • Rises steadily
    • Drops sharply
    • Remains completely flat

  20. Why does the gradient of a river become gentler as it flows towards the sea?

    • Tides push it back
    • Gravity stops working
    • Water freezes solid
    • Erosion flattens land
