S1 English: Comparatives and Superlatives (Paper 2: intermediate)
Paper two adds calculations of discharge, gradient, run-off and reservoir life, and fixes the causes of meanders and waterfalls.
Direct answers Write the units first for area times velocity, and work out per-kilometre values before comparing steepness.

02 Questions (10 items)
- FoundationA reach has an area of 35 square metres and a velocity of 0.8 metres per second. What is the discharge?
- FoundationThe upper course falls 400 metres in 20 kilometres and the lower course 60 metres in 60 kilometres. How many times steeper is the upper course?
- FoundationA lake covers 2 square kilometres and loses 6 millimetres a day to evaporation. How many cubic metres evaporate daily?
- IntermediateA catchment of 250 square kilometres receives 120 millimetres of rain with a run-off coefficient of 0.4. What is the run-off in million cubic metres?
- IntermediateSuspended load is 60 per cent and dissolved load 25 per cent of a river load. What share is the bed load?
- IntermediateA reservoir holds 3 million cubic metres and silts up by 150 000 cubic metres a year. How long does it last?
- ChallengeAnnual rainfall is 2 400 millimetres and evaporation 1 500 millimetres. What share of rainfall evaporates?
- ChallengeWhat happens at the outer and inner bends of a meander?
- ChallengeUnder which geological condition does a waterfall usually form in an upland river?
- Error redoA student says erosion is strongest in the lower course. What is wrong?
03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 28.0 cubic metres per second | Thirty-five times 0.8 gives 28.0. |
| 2 | 20 times | The upper course drops 20 metres per kilometre against 1 metre below, so 20 times. |
| 3 | 12000 cubic metres | Two square kilometres is two million square metres, and times 0.006 metres gives 12000. |
| 4 | 12.0 million cubic metres | 0.12 metres times 250 million square metres times 0.4 gives 12.0 million cubic metres. |
| 5 | 15 per cent | One hundred minus sixty minus twenty-five leaves fifteen per cent. |
| 6 | 20 years | Three million divided by 150 000 gives 20 years. |
| 7 | 62.5 per cent | Fifteen hundred divided by 2 400 times one hundred gives 62.5. |
| 8 | The outer bend erodes because flow is fast, and the inner bend deposits because flow is slow | The outer bank retreats under erosion while the inner bank builds forward, making the meander more pronounced. |
| 9 | Hard rock lying over softer rock, with the soft rock eroded faster | Differential erosion removes the soft layer first and leaves a hard step over which the water falls. |
| 10 | Erosion is strongest in the upper and middle courses; the gentle lower course is dominated by deposition. | Velocity and gradient are greatest upstream, so downcutting is concentrated there. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Then try paper three, using voltage and current to work out power and resistance.Tutor Registration →
