Secondary 4 Geography Quiz - Map Graph Data Skills (Answer Key)
Total Marks: 40
Section A: Map Skills
1. [1 mark]
1406
(Accept 1406 or 1406 only. Must be 4 figures.)
2. [2 marks]
1.0 km
(1 mark for correct measurement/calculation logic; 1 mark for correct unit and value. Distance is 2cm on map x 0.5 = 1.0km.)
3. [3 marks]
Description of Relief:
- The land is steep / has a steep gradient (1 mark).
- This is shown by the contour lines being close together (1 mark).
- The height is above 20m/30m (specific value depends on map detail, but referencing elevation gain) (1 mark).
(Must link contour spacing to slope steepness.)
4. [1 mark]
Commercial / High-density Residential / Mixed Use
(Accept any plausible zone adjacent to CBD based on standard urban models.)
5. [2 marks]
- Land value/rent is higher near the CBD (1 mark).
- Therefore, only high-density (vertical) development is economically viable to maximize profit per square metre (1 mark).
Section B: Graph Construction and Interpretation
6. [2 marks]
170 mm
- Highest: 310 mm (Dec) (0.5 mark)
- Lowest: 140 mm (Jun) (0.5 mark)
- Calculation: 310 - 140 = 170 (1 mark).
7. [2 marks]
- Rainfall is variable throughout the year (1 mark).
- There are two peaks (Nov-Dec and Jan) and a drier period in the middle of the year (Jun-Jul) (1 mark).
(Accept "no distinct dry season" if qualified with "variation exists".)
8. [4 marks]
- Title: "Monthly Rainfall in Singapore (Selected Months)" or similar (1 mark).
- Y-axis: Labelled "Rainfall (mm)" with appropriate scale (0-350) (1 mark).
- X-axis: Labelled "Month" with Jan, Jun, Dec (1 mark).
- Accuracy: Bars plotted correctly at 240, 140, and 310 (1 mark).
9. [1 mark]
Low birth rate / Declining birth rate.
10. [2 marks]
- Challenge: Ageing population / High dependency ratio (1 mark).
- Impact: Strain on healthcare services / Pension funds / Labour shortage (1 mark).
11. [2 marks]
- The temperature anomaly shows a general upward trend / increase (1 mark).
- The rate of increase has accelerated / become steeper after 2010 (1 mark).
12. [1 mark]
2020 (or the final year shown on the graph).
Section C: Data Analysis and Statistical Skills
13. [2 marks]
60.7% (or 61%)
- Working: (8.5 / 14.0) x 100 (1 mark).
- Answer: 60.71... % (1 mark).
14. [1 mark]
Pie Chart
15. [1 mark]
- It effectively shows parts of a whole / percentages / proportions (1 mark).
16. [2 marks]
108.3 (or 108)
- Working: (120 + 95 + 110) / 3 (1 mark).
- Answer: 325 / 3 = 108.33... (1 mark).
17. [3 marks]
- Site A has much higher pedestrian flow than Site B at all times (1 mark).
- Site A peaks in the morning (08:00) suggesting commuter/office activity, while Site B peaks in the evening (18:00) suggesting residential return (1 mark).
- Data reference: e.g., "Site A has 120 pedestrians at 08:00 compared to only 15 at Site B" (1 mark).
Section D: Synthesis and Evaluation
18.
(a) [1 mark]
Building height decreases as distance from the city centre increases.
(Must state relationship clearly.)
(b) [2 marks]
- Select a starting point at the city centre (1 mark).
- Measure building height at regular intervals (e.g., every 500m or every 5th building) along a transect line (1 mark).
19. [2 marks]
Disagree.
- Tables are better for showing exact values / precise data points (1 mark).
- Graphs are better for showing trends / patterns, but may lose precision (1 mark).
(Accept "Agree" if justified by "visual impact" or "ease of comparison", but must acknowledge trade-off.)
20. [2 marks]
- Wealthier areas have more access to green spaces (1 mark).
- Poorer areas have less access / green spaces are unevenly distributed favouring high-income groups (1 mark).
(Implication of positive correlation: as income goes up, access goes up.)
