S1 English: Comparatives and Superlatives (Paper 1: basics)

Paper one starts from the basic stages of the water cycle and introduces discharge, velocity and the three river processes.

Direct answers Decide first which stage changes the state of water, then handle the numerical discharge and velocity items.

03 Answers and one-line notes

# Answer One-line note
1 Evaporation Evaporation changes liquid water into vapour and is the first step of the cycle.
2 Condensation Condensation turns vapour into droplets, and the droplets gather to form clouds.
3 2.5 per cent About 97.5 per cent is salt water, leaving 2.5 per cent as fresh water.
4 30.0 cubic metres per second Discharge is area times velocity, so 20 times 1.5 gives 30.0.
5 Erosion, transportation and deposition A river erodes its bed, carries the load, and deposits it where the flow slows.
6 A V shape A steep upper course cuts down strongly, giving a narrow, deep V-shaped valley.
7 Infiltration Infiltration moves water into the soil and groundwater, which can later reach the river.
8 5 metres 600 divided by 120 gives 5, so it falls 5 metres per kilometre.
9 1.25 metres per second Fifty divided by forty gives 1.25, a common way to measure velocity.
10 The water does not vanish; the total amount is nearly conserved and only moves between sea, air and land. The cycle moves water rather than destroying it, so the total barely changes.

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.

After paper one, take paper two and sort out series against parallel in one pass.Tutor Registration →
