Answer Key and Marking Scheme
Version: 1 of 5
Section A: Map Skills (20 marks)
Question 1 (5 marks)
(a) 1853 [1]
Marking note: Accept 1853 only. Penalise reversed figures (5318) or incorrect easting/northing order. Must be 4 digits.
(b) 215474 [2]
Step-by-step:
- Easting: 21 (first two digits from grid square), estimate 5 tenths across → 215 [1]
- Northing: 47 (first two digits), estimate 4 tenths up → 474 [1]
- Common error: Reversing to 474215 loses both marks. Missing one digit loses 1 mark.
(c) South-east / SE / Southeast [1]
Concept: Direction is measured from the first named place to the second. Use North arrow, place protractor on Hillcrest, measure bearing or use compass points.
Question 2 (4 marks)
(a) Approximately 3.2 km (accept 3.0–3.4 km) [2]
Step-by-step:
- Measure straight-line distance on map with ruler (e.g., 6.4 cm) [1]
- Use scale: 1:50,000 means 1 cm = 0.5 km, or read from scale bar [1]
- Convert: 6.4 × 0.5 = 3.2 km
Acceptable range: 3.0–3.4 km depending on precise measurement.
(b) Main Road 1 follows a curved/winding route around physical features (hills, river) / road is not straight / road must follow contours [2]
Marking points: [1] for identifying road is not straight; [1] for explaining why (physical obstacles, following contours, serving settlements along the way). Accept "road winds around the coast" or similar.
Question 3 (4 marks)
(a) Vertical exaggeration = 5× (accept 5 or 5 times) [2]
Step-by-step:
- Vertical scale: 1 cm = 10 m (from graph: 1 cm represents 10 m) [0.5]
- Horizontal scale: 1 cm = 0.5 km = 500 m = 50,000 cm, so 1:50,000 [0.5]
- Or: horizontal scale 1:50,000; vertical scale 1:10,000 (10m in cm terms for direct comparison)
- Vertical exaggeration = (vertical scale fraction) ÷ (horizontal scale fraction) = 50,000/10,000 = 5 [1]
Alternative working: If vertical scale is 1 cm to 10 m and horizontal is 1 cm to 500 m, then 500/10 = 50... this needs careful handling. The standard method: convert scales to ratios (1:1000 for vertical, 1:50,000 for horizontal doesn't work directly). Better approach: Express both as representative fractions with same units.
- Vertical: 1 cm = 10 m = 1000 cm → 1:1000
- Horizontal: 1 cm = 500 m = 50,000 cm → 1:50,000
- VE = (1/1000) ÷ (1/50,000) = 50,000/1,000 = 50? No, this is incorrect.
Correction: Actually for cross-sections, vertical exaggeration is typically calculated as: VE = (Vertical scale horizontal equivalent) / (Horizontal scale horizontal equivalent), but the standard geography method is:
- If horizontal scale is 1:50,000 and vertical is 1:10,000, then VE = 50,000/10,000 = 5.
- This gives VE = 5. [1]
Teaching note: Vertical exaggeration makes small relief features visible. It = (denominator of horizontal RF) ÷ (denominator of vertical RF) when both are expressed as representative fractions.
(b) Valley / River valley / V-shaped valley [1]
Identification: Point B shows lower elevation with higher ground on either side, indicating a valley through which the river flows.
(c) Flat land / gentle slope / near water source / fertile soil from river deposits [1]
Any one valid: Proximity to water for irrigation, alluvial soil deposits, flatter land easier to cultivate.
Question 4 (5 marks)
(a) May [1]
(28.5°C)
(b) 2228 mm [2]
Step-by-step:
- Add all monthly values: 234 + 112 + 170 + 155 + 171 + 132 + 154 + 148 + 177 + 198 + 258 + 319 [1]
- = 2228 mm [1]
Allow 1 mark for correct method with minor addition error.
(c) Pattern description [2]
Marking points:
- [1] Bimodal pattern / two peaks / generally high rainfall throughout the year with no month below 100mm
- [1] Peaks in November–January and lower period in June–July specifically / wettest in December (319mm), driest in February (112mm) but still substantial
Expected answer: Rainfall is generally high all year but shows two peaks — one around November–December (monsoon season) and lower amounts in early-mid year. The wettest months are November to January; the "driest" month (February) still has over 100mm.
Question 5 (3 marks)
(a) Equatorial climate / Tropical rainforest climate [1]
(b) Two pieces of evidence [2]
Marking points — any two from:
- [1] High temperature throughout: 26–28°C consistently / small annual range (less than 2°C between hottest and coolest)
- [1] High rainfall every month: no month below approximately 150mm / all months wet
- [1] Total annual rainfall exceeds 2000mm (accept calculation if shown: approx 2500+ mm)
- [1] No distinct dry season / rainfall evenly distributed or with slight peaks but consistently heavy
Question 6 (3 marks)
(a) Emergent layer [1]
(b) Two adaptations [2]
Marking points:
- [1] Broad, waxy/drip-tip leaves allow water to run off quickly / prevent waterlogging and fungal growth
- [1] Buttress roots provide stability in shallow, wet soils / support tall growth in nutrient-poor conditions
- [1] Lianas climb to reach sunlight in dense canopy / rapid growth to access light
Any two distinct adaptations with explanations accepted. Must link to high rainfall specifically.
Question 7 (4 marks)
(a) 40% [2]
Step-by-step:
- Urban population ÷ Total population × 100 [1]
- = 52 ÷ 130 × 100 = 0.4 × 100 = 40% [1]
Common error: Forgetting ×100 gives 0.4 (no mark for final answer).
(b) Country A [1]; 90% urban (45/50) is highest percentage [1]
Step-by-step:
- Country A: 45/50 = 90%
- Country B: 40% (from a)
- Country C: 5/25 = 20%
- Country D: 56/80 = 70%
Country A has highest proportion/percentage, not necessarily highest absolute number. [2]
Question 8 (3 marks)
(a) 40% [1]
25% + 15% = 40%
(b) Two reasons [2]
Marking points:
- [1] Limited land area: Singapore is small (728 km²), so land is prioritised for housing and industry
- [1] Most food is imported rather than grown locally / urban economy focuses on services and manufacturing not agriculture
- [1] High cost of agricultural land / more profitable uses for land
- [1] Climate constraints / focus on high-tech urban farming rather than traditional agriculture
Section A Total: 20 marks
Section B: Data Analysis and Interpretation (25 marks)
Question 9 (4 marks)
(a) River R [1]; lowest turbidity (8 NTU), highest dissolved oxygen (9.0 mg/L), lowest BOD (1 mg/L), pH closest to neutral-alkaline healthy range [1]
Reasoning: Clean water requires high dissolved oxygen ( aquatic life), low turbidity (clear water), low BOD (little organic pollution), pH 6.5–8.5. River R meets all criteria best. River Q and S show pollution indicators.
(b) Two effects [2]
Marking points:
- [1] Lowers dissolved oxygen: organic waste decomposes, using up oxygen / BOD increases
- [1] Increases turbidity: suspended solids from industrial processes cloud the water
- [1] Alters pH: acidic or alkaline chemicals change pH outside safe range
- [1] Toxic substances may directly harm aquatic life
Any two distinct effects with correct link to measurements.
Question 10 (4 marks)
(a) 33 m above sea level; July [1]
Both required for mark.
(b) Range = 44 − 33 = 11 m [1]
(c) Two reasons [2]
Marking points:
- [1] July is within drier period / Southwest Monsoon / less rainfall than other months
- [1] Higher evaporation due to strong sunshine / higher temperatures
- [1] Increased water usage for irrigation/cooling during hot period
- [1] Less storm events / no major rain-carrying weather systems
Must relate to Singapore's climate context.
Question 11 (4 marks)
(a) Positive correlation / direct relationship [1]; as rainfall increases, river discharge generally increases [1]
More detail: Generally strong positive — when rainfall is 100–300mm, discharge rises from 5 to ~40 cumecs. Not perfect due to outlier.
(b) Possible reasons for outlier [1]
- Heavy rainfall after long dry period / ground very dry so infiltration high, runoff low
- Rain fell in area not contributing to this river catchment
- Man-made interference (dam release, water abstraction)
- Time lag: rain fell at end of month, peak flow next month not shown
Any reasonable geographical explanation.
(c) Shows pattern/trend clearly / helps identify relationships between two continuous variables / can see strength and direction of correlation [1]
Question 12 (4 marks)
(a) Central [1]
(b) Two reasons [2]
Marking points:
- [1] Economic opportunities: jobs in CBD/services/financial sector attract people
- [1] Better infrastructure and amenities: transport, schools, healthcare
- [1] Historical development: city grew from this centre
- [1] Accessibility: transport hub, port location
(c) Disadvantage [1]
- Shows average for whole region / masks internal variation / different densities within same colour zone
- Arbitrary boundaries create artificial steps / small areas of extreme density hidden
- Doesn't show actual population numbers, only density categories
Question 13 (4 marks)
| Letter | Process | Mark |
|---|---|---|
| A | Evaporation | [1] |
| B | Transpiration | [1] |
| C | Condensation | [1] |
| D | Precipitation | [1] |
Teaching note: These are key flows in the hydrological cycle. A = water heated by sun becomes vapour from ocean; B = plants release water through leaves; C = water vapour cools and forms droplets; D = water falls as rain/snow.
Question 14 (5 marks)
(a) Two changes with data [2]
Marking points — any two from:
- [1] Natural gas increased from 78% to 95% (increase of 17 percentage points)
- [1] Oil decreased significantly from 20% to 3% (decrease of 17 percentage points)
- [1] Coal remained constant at 1%
- [1] Solar remained very small at 1%
(b) One reason [1]
- Natural gas burns cleaner than oil/coal (lower carbon emissions per unit energy)
- More reliable supply / secure domestic processing capability
- Singapore has infrastructure for natural gas import and processing
- Regional availability and pipeline/delivery infrastructure
(c) Two strategies [2]
Marking points:
- [1] Increase solar power deployment / expand solar panel installation on rooftops and reservoirs
- [1] Invest in regional renewable energy imports / regional power grid
- [1] Improve energy efficiency / demand reduction through technology and building standards
- [1] Research and develop other renewables (tidal, geothermal, hydrogen)
- [1] Expand NEWater and waste-to-energy programmes
Section B Total: 25 marks
Section C: Application and Evaluation (15 marks)
Question 15 (4 marks)
(a) Evaluation of industrial zone B [2]
Marking points:
Positives:
- [1] Located away from residential village to west / reduces noise/air pollution impact on residents
- [1] Access to main road for transport of goods
Negatives:
- [1] If prevailing wind from west, pollution may still reach village
- [1] River to north may receive industrial runoff if not properly managed
Balanced evaluation expected for full marks. Must mention sustainability implication.
(b) Evaluation of park/nature reserve C [2]
Marking points:
Positives:
- [1] Adjacent to existing forested area / extends green corridor / maintains habitat connectivity
- [1] Preserves biodiversity / natural drainage / reduces urban heat island effect
Negatives:
- [1] Takes land that could be used for housing/industry (opportunity cost)
- [1] May fragment if not properly connected
Full marks for balanced assessment with sustainability focus.
Question 16 (5 marks)
(a) 855 million litres / 855,000 m³ [2]
Step-by-step:
- Total daily demand = population × per person demand [1]
- = 5,700,000 × 150 litres = 855,000,000 litres = 855 million litres [1]
- Or: 5.7 million × 150 = 855 million litres
Units not required for marks but good practice.
(b) Two reasons with explanation [3]
Marking points:
Reason 1: Technology and investment in water supply [2 max]
- [1] Country X (Singapore) has invested heavily in advanced water treatment (NEWater, desalination)
- [1] These technologies reduce dependence on rainfall and natural surface water / create "four national taps" for security
Reason 2: Efficiency and demand management [2 max]
- [1] Lower per capita water demand (150 vs 200 litres/day) through conservation and efficient use
- [1] Despite smaller land area, intensive infrastructure and management overcomes natural limitations
Reason 3: Economic capacity [2 max]
- [1] Higher GDP per capita enables investment in expensive water technology
- [1] Country Y has more land and rain but less capacity to store/treat/distribute effectively
Full marks require explicit comparison and use of table data plus geographical reasoning.
Question 17 (4 marks)
(a) Seawall / Hard engineering / Revetment (accept seawall specifically) [1]
(b) Advantage and disadvantage [2]
Advantage [1]: Immediate, strong protection against storm waves / long-lasting structure / prevents erosion behind wall / protects valuable land
Disadvantage [1]: Expensive to build and maintain / reflects wave energy causing scour at base / can fail catastrophically if undermined / unnatural appearance / prevents beach accumulation / damages ecosystem
Comparison to soft engineering required in explanation for full marks.
(c) Reason for hard engineering preference [1]
- Limited land area / high population density requires maximum protection
- Valuable infrastructure (airport, industry, housing) behind coast needs guaranteed protection
- Soft engineering takes more space that Singapore doesn't have
- Greater control and predictability for dense development
Question 18 (5 marks)
(a) Relationship [2]
Marking points:
- [1] As building density increases, temperature increases (positive correlation)
- [1] Data support: CBD very high density, highest temperatures (31.5°C day, 28.2°C night); nature reserve very low density, lowest temperatures (28.0°C day, 24.5°C night)
Must use data for second mark.
(b) Two ways vegetation reduces temperature [2]
Marking points:
- [1] Shade / intercepts solar radiation, reducing ground heating
- [1] Transpiration / evapotranspiration releases water vapour, cooling surrounding air
- [1] Reduces urban heat island effect by replacing heat-absorbing surfaces
- [1] Wind channels through vegetation create cooling breezes
(c) One strategy [1]
- Cool/coloured roofing materials / green roofs
- Building orientation for ventilation / wind corridors
- Water features / fountains for evaporative cooling
- Reduce energy consumption / less waste heat from buildings
- Use of permeable surfaces to reduce heat retention
