TuitionGoWhere Practice Paper — Geography H2 A-Level (Version 5) Answer Key
Total Marks: 60 — Section A 18, Section B 24, Section C 18.
Section A Answers (18 marks)
Q1 [4 marks]
- Ecosystem services = benefits that humans obtain from ecosystems (1 mark).
- Four categories (1 mark each): provisioning (food, water, timber), regulating (climate, flood control), cultural (recreation, spiritual), supporting (nutrient cycling, soil formation).
- Teaching note: From syllabus 1.1; students must name all four, not just define. Common mistake: listing examples but not category names.
Q2 [2 marks]
- Proven reserves: resources confirmed by exploration and economically extractable with current tech (1 mark).
- Speculative reserves: hypothesised resources in unexplored areas, uncertain existence and extractability (1 mark).
- Marking: 1 each for contrast in certainty and accessibility.
Q3 [3 marks]
- R/P = 1,200 / 40 = 30 years (2 marks for calculation, 1 mark for indication).
- Indicates: at current rate, supply lasts 30 years; moderate security but finite (1 mark).
- Working: . Unit: years.
Q4 [2 marks]
- Limitation: Malthus ignored technological innovation that can raise resource limits (e.g., Boserup effect) (2 marks). Or: uneven access means scarcity is distributional not absolute.
- Accept any one clear limitation with explanation.
Q5 [2 marks]
- Boserup: population pressure stimulates technological change that expands resource base (1 mark); differs from Malthus who saw fixed limits (1 mark).
Q6 [3 marks]
- Variation: Country A lowest (8%), E highest (93%) (1); upward gradient A<B<C<D<E (1); E near full withdrawal signals stress (1).
- Must reference chart values from placeholder.
Q7 [2 marks]
- Trade-off: floodplain habitat loss / methane from reservoirs / displaced communities (1 mark + 1 for environmental/social link).
Section B Answers (24 marks)
Q8 [5 marks]
- City S highest overall (75), City R lowest (56) (1).
- Q (72) and P (71) similar mid-high (1).
- P strong social (81) weak env (58); Q strong env (83) weak social (64) (1).
- R lags all dimensions (1).
- Pattern: no city leads all; trade-offs visible (1).
- Marking: comparative language required, not raw list.
Q9 [3 marks]
- City P: 81−58 = 23 (1 identify, 2 calc). Or Q: 83−64=19. Largest = P gap 23.
- Mark: 1 id, 2 arithmetic.
Q10 [4 marks]
- Targets quantify aims (1); indicators track change over time (1); allow comparison across space (1); reveal trade-offs (1).
- Teaching: links to SDG syllabus point on measurement challenges.
Q11 [2 marks]
- Steady rise from 0.8 to 1.9 kg/day (1); ~138% increase (1).
Q12 [4 marks]
- Reasons: urban consumption growth (2); inadequate recycling (2). Or: income rise, packaging use.
- 2 marks each, explained.
Q13 [3 marks]
- Mekong shared with State Y (1); conflict: upstream withdrawal reduces downstream flow (2).
Q14 [3 marks]
- Useful: reveals trade-offs numerically (1); but narrow indicators miss qualitative loss (1); needs context (1).
- Descriptor: balanced judgement.
Section C Answers (18 marks)
Q15 [7 marks]
- Limestone soluble CaCO₃ (1)
- Rain + CO₂ → H₂CO₃ (1)
- Dissolves rock along joints (1)
- Infiltration/percolation (1)
- Cavity enlargement (1)
- Sinkholes from collapse (1)
- Long-term, climate-dependent (1)
Q16 [5 marks]
- CO₂ per $1m = 45,000 / 120 = 375 tonnes (3 marks: 2 calc, 1 unit).
- Social limit: land contest with farmers / visual impact (2 marks).
Q17 [4 marks]
- Depth 12→41m, yield 1.2→0.4 t/ha: depletion cuts yield (2).
- Strategy: rainwater harvesting / regulated pumping (2).
Q18 [2 marks]
- High capital cost (1); advanced tech for extraction (1).
Q19 [4 marks]
- Agree: reduces waste, resource efficiency (2).
- Counter: infra cost, behaviour change hard (2).
Q20 [2 marks]
- Guano as ecological provisioning (1); Haber-Bosch shifted to industrial base via tech/demand (1).
