A-Level Geography H1 Quiz - Map Graph Data Skills – ANSWER KEY
Total Marks: 40
Section A: Map Interpretation Skills (Questions 1–5)
Total Marks: 10
1. State the six-figure grid reference for the northern tip of MacRitchie Reservoir. [1 mark]
Answer: 288 416 (accept 287–289 415–417)
Marking note: Award 1 mark for a six-figure grid reference within the acceptable range. Easting must be given first.
2. Calculate the straight-line distance in kilometres between the Central Expressway (CTE) exit at grid reference 285 412 and the summit of Bukit Timah Hill at grid reference 295 418. Show your working. [2 marks]
Answer:
- Easting difference: 295 – 285 = 10 (units)
- Northing difference: 418 – 412 = 6 (units)
- Grid distance = √(10² + 6²) = √(100 + 36) = √136 ≈ 11.66 units
- Scale 1:25,000 means 1 unit = 1 km (since 1 grid square = 1 km on 1:25,000 maps with 4 cm grid squares)
- Distance ≈ 11.66 km
Marking note: Award 1 mark for correct method (Pythagoras or equivalent), 1 mark for correct answer with units. Accept 11.7 km.
3. Describe the relief of the area shown in the map extract. Support your answer with evidence from the map. [3 marks]
Answer:
The relief is generally undulating/hilly, with higher ground in the west/southwest (Bukit Timah Nature Reserve area) and lower ground around MacRitchie Reservoir in the east. Contour lines are closely spaced around Bukit Timah Hill, indicating steep slopes, while wider contour spacing around the reservoir indicates gentler slopes. The highest point is Bukit Timah Hill (approximately 163 m), and the lowest areas are around the reservoir and stream valleys.
Marking note: Award 1 mark for identifying general relief (hilly/undulating), 1 mark for using contour evidence (spacing, height), 1 mark for identifying specific high/low points. Accept alternative valid descriptions with map evidence.
4. Identify the direction of flow of the stream entering the northern end of MacRitchie Reservoir. Explain how you determined this. [2 marks]
Answer:
The stream flows southwards/south-eastwards into the reservoir. This is determined by the contour lines, which show decreasing elevation towards the reservoir (contour lines point upstream, forming a V-shape pointing upstream). Water flows from higher to lower elevation.
Marking note: Award 1 mark for correct direction, 1 mark for valid explanation referencing contours/elevation.
5. Explain how the topography of the area shown in the map extract would influence surface runoff during a heavy rainfall event. [2 marks]
Answer:
Steep slopes (e.g., around Bukit Timah Hill) would experience rapid surface runoff, increasing flood risk downstream. Gentle slopes (e.g., around the reservoir) would allow more infiltration, reducing runoff. The presence of the reservoir would capture runoff from surrounding slopes, potentially reducing downstream flooding.
Marking note: Award 1 mark for identifying steep slopes = rapid runoff, 1 mark for linking to flood risk or infiltration. Accept alternative valid explanations with topographic reasoning.
Section B: Graph and Data Analysis Skills (Questions 6–15)
Total Marks: 20
6. Calculate the mean annual temperature for Singapore in 2023. Show your working and give your answer to one decimal place. [2 marks]
Answer:
Sum of temperatures = 26.5 + 27.0 + 27.5 + 27.8 + 28.0 + 27.8 + 27.5 + 27.3 + 27.0 + 26.8 + 26.5 + 26.2 = 325.9
Mean = 325.9 ÷ 12 = 27.158... ≈ 27.2°C
Marking note: Award 1 mark for correct method (sum/12), 1 mark for correct answer (27.2°C). Accept 27.2°C only.
7. Describe the relationship between temperature and rainfall shown in Resource 2. Support your answer with data. [3 marks]
Answer:
There is a weak inverse relationship between temperature and rainfall. Temperature is highest in April–May (27.8–28.0°C) when rainfall is moderate (172–178 mm), while the highest rainfall occurs in December (298 mm) when temperature is lowest (26.2°C). However, the relationship is not consistent throughout the year (e.g., January has high rainfall but moderate temperature).
Marking note: Award 1 mark for identifying inverse/weak relationship, 1 mark for using specific data, 1 mark for noting inconsistency. Accept alternative valid descriptions with data support.
8. Calculate the total annual rainfall for Singapore in 2023. [1 mark]
Answer:
242 + 168 + 185 + 178 + 172 + 162 + 158 + 175 + 189 + 208 + 252 + 298 = 2,387 mm
Marking note: Award 1 mark for correct answer with units. Accept 2,387 mm.
9. Identify the month with the highest rainfall and state one possible reason for this peak. [2 marks]
Answer:
December (298 mm). Possible reason: Northeast Monsoon brings heavy rainfall to Singapore during November–January.
Marking note: Award 1 mark for correct month, 1 mark for valid reason (monsoon, seasonal rainfall pattern). Accept other valid geographical reasons.
10. Calculate the percentage increase in population for City B between 2000 and 2020. Show your working. [2 marks]
Answer:
Increase = 18.7 – 12.0 = 6.7 million
Percentage increase = (6.7 ÷ 12.0) × 100 = 55.83% ≈ 55.8%
Marking note: Award 1 mark for correct method, 1 mark for correct answer. Accept 55.8% or 55.83%.
11. Using Resource 3, identify which city experienced the highest absolute increase in population. Explain your answer. [2 marks]
Answer:
City B experienced the highest absolute increase (6.7 million), compared to City A (3.8 million) and City C (4.6 million). This is calculated by subtracting 2000 population from 2020 population for each city.
Marking note: Award 1 mark for identifying City B, 1 mark for showing calculation or comparison.
12. Explain one limitation of using the data in Resource 3 to compare urban growth rates across the three cities. [2 marks]
Answer:
The data only shows population at two points in time (2000 and 2020), so it does not show the rate of growth over time or any fluctuations between these years. Additionally, the cities may have different base populations, making direct comparison of absolute growth misleading (e.g., a smaller city may have a higher percentage growth rate).
Marking note: Award 1 mark for identifying a valid limitation, 1 mark for explanation. Accept other valid limitations (e.g., no information on city boundaries, migration patterns, or natural increase vs. net migration).
13. Describe the general relationship shown in Resource 4. [2 marks]
Answer:
There is a positive correlation between GDP per capita and carbon emissions per capita. Countries with higher GDP per capita tend to have higher carbon emissions per capita. However, there are some outliers that do not follow this trend.
Marking note: Award 1 mark for identifying positive correlation, 1 mark for noting outliers or variation. Accept alternative valid descriptions.
14. Identify one country that is an outlier in Resource 4. Suggest one possible reason for this outlier status. [2 marks]
Answer:
Possible outlier: A country with high GDP but low emissions (e.g., Norway with hydropower) or a country with low GDP but high emissions (e.g., an oil-producing nation). Reason: Norway relies heavily on renewable energy (hydropower), reducing its carbon emissions despite high GDP. Alternatively, an oil-producing country may have high emissions from extraction industries despite lower GDP.
Marking note: Award 1 mark for identifying a plausible outlier, 1 mark for valid reason. Accept other valid examples and reasons.
15. Evaluate the usefulness of Resource 4 for understanding the relationship between economic development and environmental impact. [2 marks]
Answer:
Resource 4 is useful because it shows a clear visual correlation between GDP and emissions, suggesting economic development is linked to environmental impact. However, it is limited because it only shows a snapshot (2020), does not account for historical emissions, and does not show other environmental impacts beyond carbon emissions. The small sample size (15 countries) may not be representative of global patterns.
Marking note: Award 1 mark for identifying a strength, 1 mark for identifying a limitation. Accept other valid evaluations.
Section C: Data Presentation and Fieldwork Skills (Questions 16–20)
Total Marks: 10
16. Calculate the mean pedestrian count for Site X. Show your working. [2 marks]
Answer:
Sum = 245 + 312 + 278 = 835
Mean = 835 ÷ 3 = 278.33 ≈ 278.3 pedestrians per 10 minutes
Marking note: Award 1 mark for correct method, 1 mark for correct answer. Accept 278.3 or 278.
17. Suggest one reason for the difference in pedestrian counts between Site X and Site Y at 0800–0810. [2 marks]
Answer:
Site X may be located near a transport hub (e.g., MRT station, bus interchange) where commuters arrive for work, while Site Y may be in a less accessible area or further from public transport nodes. Alternatively, Site X could be near office buildings where workers arrive early, while Site Y could be in a residential area where people leave later.
Marking note: Award 1 mark for plausible reason, 1 mark for linking to time of day (morning peak). Accept other valid geographical reasons.
18. A student proposes to present the data in Resource 5 as a line graph. Evaluate the suitability of this method of data presentation. [2 marks]
Answer:
A line graph is suitable because it shows temporal changes clearly, with time on the x-axis and pedestrian count on the y-axis. It would allow easy comparison of trends between Site X and Site Y. However, a line graph implies continuous data, whereas the data is only collected at three discrete time points, so a bar chart might be more appropriate for discrete categories.
Marking note: Award 1 mark for identifying suitability (shows trends), 1 mark for identifying limitation (discrete data). Accept other valid evaluations.
19. Explain how the students could improve the reliability of their pedestrian count data. [2 marks]
Answer:
Students could repeat the count on multiple days to account for daily variations, increase the counting duration (e.g., 30 minutes instead of 10 minutes), use multiple counters at each site to cross-check counts, or use automated counters (e.g., video recording) to reduce human error.
Marking note: Award 1 mark for each valid suggestion with explanation. Accept other valid methods.
20. Using Resource 5, describe the temporal pattern of pedestrian counts at Site Y. [2 marks]
Answer:
Pedestrian counts at Site Y increase throughout the day, from 89 at 0800–0810 to 156 at 1200–1210, and further to 210 at 1800–1810. The highest count is in the evening, suggesting Site Y may be near evening activity areas (e.g., shopping, dining).
Marking note: Award 1 mark for describing increase, 1 mark for using data or suggesting reason. Accept alternative valid descriptions with data support.
