A-Level Geography H1 Quiz - Map Graph Data Skills (Answer Key)
Total Marks: 40
Section A: Graph and Statistical Interpretation
1. Describe the overall trend in global mean surface temperature anomalies shown in Resource 1 from 1980 to 2020. [2]
- Answer: There is a clear overall upward trend (warming) in temperature anomalies, rising from approximately -0.2°C in 1980 to +1.0°C in 2020. [1] The rate of warming appears to accelerate in the later years (post-2010). [1]
- Marking Note: Accept "increasing trend" or "positive correlation with time." Must cite data values for full marks.
2. Identify the specific anomaly visible in the data around 1991–1992 and suggest one natural cause for this temporary deviation. [2]
- Answer: There is a temporary dip or decrease in temperature anomalies. [1] This was likely caused by the eruption of Mount Pinatubo, which released aerosols/sulphur dioxide into the stratosphere, reflecting solar radiation and causing temporary cooling. [1]
- Marking Note: Accept "volcanic eruption" generally if specific mechanism (reflection of sunlight) is implied or stated.
3. Calculate the percentage change in Industrial land use in City X from 2000 to 2020. Show your working. [2]
- Answer:
- Initial Value (2000): 30%
- Final Value (2020): 15%
- Change: 15 - 30 = -15
- Percentage Change: (-15 / 30) * 100 = -50% [1 for working, 1 for correct answer -50%]
- Marking Note: Accept "decrease of 50%" or "halved."
4. With reference to Resource 2, describe two significant changes in the urban structure of City X between 2000 and 2020. [2]
- Answer:
- Industrial land use decreased significantly (from 30% to 15%). [1]
- Commercial and Green Space land use increased (Commercial doubled from 10% to 25%; Green Space increased from 20% to 25%). [1]
- Marking Note: Must reference specific categories. "Residential decreased slightly" is also valid.
5. Suggest one socio-economic factor that might explain the increase in Commercial land use shown in Resource 2. [2]
- Answer: Economic growth or tertiary sector expansion has increased demand for office and retail space. [1] This leads to the conversion of former industrial or residential land into commercial zones to maximize land value. [1]
- Marking Note: Accept "gentrification," "shift to service economy," or "urban renewal policies."
Section B: Map and Spatial Pattern Analysis
6. Describe the spatial distribution of 'High Flood Risk' areas shown in Resource 3. [2]
- Answer: High flood risk areas are concentrated in the low-lying floodplain (Zone B) and the coastal estuary (Zone C). [1] They are located adjacent to the river channel and the coast, avoiding the higher elevation inland areas (Zone A). [1]
- Marking Note: Must use locational language (e.g., "along the river," "coastal," "low-lying").
7. Explain why Zone B (the floodplain) is classified as high risk, referencing both physical and human factors visible or implied in the map. [3]
- Answer:
- Physical: Zone B has low elevation/flat terrain, leading to slow drainage and water accumulation during heavy rainfall or high tides. [1]
- Human: The presence of urban areas (buildings/infrastructure) creates impermeable surfaces, increasing surface runoff and reducing infiltration. [1]
- Synthesis: The combination of natural susceptibility (low land) and human modification (urbanization) exacerbates flood risk. [1]
8. Identify the area with the highest population density on Resource 4 and suggest one reason for this concentration. [2]
- Answer: The Central Area (CBD) or mature estates like Tampines show the highest density. [1] This is due to high-rise public housing (HDB) developments and proximity to employment opportunities/amenities. [1]
- Marking Note: Accept any dark-shaded area identified correctly. Reason must link to vertical growth or land scarcity.
9. Contrast the population density of the Nature Reserve area with the Central Area. Explain this difference using urban planning concepts. [3]
- Answer: The Nature Reserve has very low density (light shade), while the Central Area has high density (dark shade). [1] This difference is due to zoning laws that protect green spaces for conservation and recreation, prohibiting residential development. [1] In contrast, the Central Area is zoned for high-density mixed-use development to maximize land efficiency in a land-scarce city. [1]
10. A student claims that "Population density is evenly distributed across Singapore." Using evidence from Resource 4, refute this claim. [2]
- Answer: The claim is incorrect because the map shows distinct variations in shading. [1] There are clear clusters of high density (dark areas) and large areas of low density (light areas like the west/nature reserves), indicating an uneven distribution. [1]
Section C: Data Presentation and Fieldwork Methodology
11. State an appropriate hypothesis for this investigation. [1]
- Answer: "Infiltration rates are higher in areas with SUDS (e.g., permeable pavement) compared to areas with traditional impermeable surfaces."
- Marking Note: Must be a testable statement linking SUDS to infiltration/runoff.
12. The students plan to measure infiltration rates. Describe one suitable method they could use to collect primary data on infiltration. [2]
- Answer: Use a double-ring infiltrometer. [1] Pour water into the rings and measure the time taken for the water level to drop by a specific amount, calculating the rate (mm/hr). [1]
- Marking Note: Accept "pouring known volume of water and timing drainage" if method is clear.
13. Explain why it is important for the students to collect data at multiple sites within the park rather than just one location. [2]
- Answer: To ensure the data is representative of the whole area and to account for spatial variability (e.g., soil type differences, slope). [1] It allows for the identification of patterns and reduces the impact of anomalies/outliers. [1]
14. The students decide to present their infiltration data using a bar chart. Justify why a bar chart is an appropriate choice for this specific dataset. [2]
- Answer: A bar chart is suitable for comparing discrete categories (e.g., Site A with SUDS vs. Site B without SUDS). [1] It allows for easy visual comparison of the mean infiltration rates between the different land use types. [1]
15. Identify one potential source of error in their fieldwork data collection and suggest a way to minimize it. [2]
- Answer:
- Error: Human reaction time when using a stopwatch. [1]
- Minimization: Use digital data loggers or repeat measurements multiple times and calculate an average. [1]
- Alternative: Error: Soil saturation varying by time of day. Minimization: Conduct all tests at the same time of day.
Section D: Synthesis and Evaluation of Resources
16. Which sector is the largest contributor to carbon emissions in Country Z? [1]
- Answer: Energy Sector (50%).
17. Calculate the ratio of Energy sector emissions to Transport sector emissions. [1]
- Answer: 150 : 60, which simplifies to 2.5 : 1 (or 5:2).
18. A policy maker suggests focusing solely on the Waste sector to reduce emissions. Using Resource 5, evaluate the potential impact of this strategy. [2]
- Answer: This strategy would have limited impact because the Waste sector only contributes 5% of total emissions. [1] Even eliminating all waste emissions would not significantly lower the total compared to targeting the Energy (50%) or Transport (20%) sectors. [1]
19. Describe two characteristics of the settlement shown in Resource 6. [2]
- Answer:
- High density of housing with little space between buildings. [1]
- Buildings appear self-built/informal, located on steep/unstable terrain (hillside). [1]
- Alternative: Lack of visible formal infrastructure (paved roads, drains).
20. Evaluate the usefulness of Resource 6 (a single photograph) in understanding the overall liveability of informal settlements in a city. [2]
- Answer: The photograph is useful for providing visual evidence of physical conditions (housing quality, density). [1] However, it is limited because it is a single snapshot in time and space; it does not provide data on social aspects (community ties, safety) or quantitative data (access to services, income levels), so it cannot represent the "overall" liveability of all settlements.
