Answer Key and Marking Scheme (Version 5)

Subject: Geography
Level: Secondary 3
Topic: Map, Graph, Data Skills


Section A: Map Skills and Spatial Analysis

1. (a) [1 mark]

  • Correct four-figure grid reference for the High-Density Housing Estate (e.g., 1234). Accept any valid 4-figure ref based on the hypothetical map description.

1. (b) [2 marks]

  • 1 mark: Direction (e.g., South-East).
  • 1 mark: Relative location detail (e.g., "It is located to the South-East of the Park" or "Across the main road").

1. (c) [2 marks]

  • 1 mark: Identification of wind direction/pollution dispersion.
  • 1 mark: Explanation (e.g., "In tropical regions, prevailing winds often blow from the South-West or North-East. Placing industry downwind prevents smoke/pollution from blowing into the residential park area.").

2. (a) [1 mark]

  • Area A has a higher proportion of Green/Open Space (25%) compared to Area B (10%).

2. (b) [2 marks]

  • 1 mark: Identification (Area B is likely higher density).
  • 1 mark: Explanation (Area B has less green space and more commercial/industrial land, suggesting higher built-up density and potentially higher population concentration in smaller living spaces, or Area A has more open space indicating lower density sprawl). Note: Accept logical inference based on land use.

3. (a) [1 mark]

  • Sketch map.

3. (b) [2 marks]

  • 1 mark: Limitation (e.g., Lack of scale, lack of precise contour details, not to scale).
  • 1 mark: Explanation (e.g., "Without a scale, planners cannot calculate exact distances or areas for construction," or "It does not show elevation changes which are crucial for drainage planning.").

Section B: Graph Interpretation and Data Analysis

4. (a) [1 mark]

  • 1°C - 2°C (e.g., 27°C to 28°C). Accept small range based on visual interpretation of "flat" line.

4. (b) [2 marks]

  • 1 mark: Pattern description (e.g., "Rainfall is distributed throughout the year with no true dry month").
  • 1 mark: Detail (e.g., "There are two peak periods: Nov-Jan and Jun-Aug").

4. (c) [2 marks]

  • 1 mark: Evaluation (Disagree).
  • 1 mark: Evidence (e.g., "Even the lowest rainfall months have significant precipitation (e.g., >100mm), so it is not a 'dry' season in the strict sense.").

5. (a) [1 mark]

  • Air transport.

5. (b) [2 marks]

  • 1 mark: Reason (e.g., Health concerns, slower recovery of cruise lines, capacity restrictions).
  • 1 mark: Elaboration (e.g., "Cruise ships involve close confinement, making them less attractive post-pandemic," or "Flight capacities were restored faster than cruise schedules.").

6. (a) [1 mark]

  • Negative correlation / Inverse relationship (As distance increases, land value decreases).

6. (b) [2 marks]

  • 1 mark: Accessibility/Agglomeration.
  • 1 mark: Explanation (e.g., "CBD has the highest accessibility and concentration of businesses, leading to high demand for limited land, which drives up prices.").

7. (a) [1 mark]

  • 570 (120 + 150 + 300).

7. (b) [2 marks]

  • 1 mark: Comparison (Shop A has much higher flow overall).
  • 1 mark: Pattern detail (e.g., "Shop A peaks in the evening (6 PM), while Shop C remains relatively stable/low in the evening.").

7. (c) [2 marks]

  • 1 mark: Reason (e.g., Shop C is near a park).
  • 1 mark: Explanation (e.g., "Parks may close or become less accessible in the evening, or people go home after work rather than to the park, whereas Shop A is near the MRT where commuters pass through.").

Section C: Fieldwork Methods and Data Presentation

8. (a) [1 mark]

  • Data collected firsthand by the researcher for a specific purpose.

8. (b) [1 mark]

  • Allows collection of opinions/attitudes/perceptions (which observation cannot capture).

8. (c) [2 marks]

  • 1 mark: Difficulty (e.g., Hard to generate a random list of all visitors).
  • 1 mark: Explanation (e.g., "Visitors are moving and transient; you cannot easily assign numbers to every person to pick randomly, making systematic or convenience sampling more practical.").

9. (a) [2 marks]

  • 1 mark: Physical feature (e.g., River bank, vegetation, soil).
  • 1 mark: Human feature (e.g., Litter, trash, concrete edge).

9. (b) [2 marks]

  • 1 mark: Annotation benefit (e.g., Adds context/explanation).
  • 1 mark: Explanation (e.g., "Annotations allow the student to label specific features like 'erosion' or 'types of litter' directly on the image, making the analysis clearer than a standalone photo.").

10. (a) [1 mark]

  • To identify anomalies/outliers and calculate a more reliable average (mean).

10. (b) [2 marks]

  • 1 mark: Explanation of mean sensitivity.
  • 1 mark: Context (e.g., "The siren is an anomaly not representative of normal noise. Including it skews the mean higher, giving a false impression of typical noise levels.").

11. (a) [1 mark]

  • Volume/Number of tourists.

11. (b) [2 marks]

  • 1 mark: Spatial element.
  • 1 mark: Explanation (e.g., "A flowline map shows the direction and origin of movement spatially, which a bar chart cannot do.").

12. (a) [1 mark]

  • Bar chart (or Pie chart).

12. (b) [1 mark]

  • Because the data is categorical/discrete (not continuous).

13. (a) [1 mark]

  • The section with the steepest gradient (closest contour lines/steepest line slope on profile).

13. (b) [2 marks]

  • 1 mark: Construction relevance.
  • 1 mark: Explanation (e.g., "It shows elevation changes, helping engineers plan for foundation depth, drainage, and road gradients.").

14. (a) [1 mark]

  • The phenomenon where urban areas are significantly warmer than surrounding rural areas.

14. (b) [1 mark]

  • Take readings at the same time of day / Use calibrated instruments / Hold instrument at same height.

15. (a) [1 mark]

  • Site X (Grassland). Shorter time = faster infiltration.

15. (b) [2 marks]

  • 1 mark: Soil structure/Permeability.
  • 1 mark: Explanation (e.g., "Grassland soil is porous and has root channels allowing water to pass through. Compacted paths have compressed soil particles, reducing pore space and slowing infiltration.").

Section D: Synthesis and Evaluation

16. (a) [2 marks]

  • 1 mark: Reliability/Validity.
  • 1 mark: Explanation (e.g., "Using multiple sources reduces bias. If traffic data and population data both support the location, the decision is more robust than relying on just one dataset.").

16. (b) [1 mark]

  • Informed consent / Anonymity / Privacy.

17. (a) [1 mark]

  • Assumes uniform distribution within the district (intra-district variation is hidden).

17. (b) [2 marks]

  • 1 mark: Boundary issue explanation.
  • 1 mark: Impact (e.g., "A high-crime spot right on the border might be averaged out with a low-crime area in the same district, masking the hotspot.").

18. (a) [1 mark]

  • Time-saving / Cost-effective / Access to large-scale/long-term data.

18. (b) [1 mark]

  • Data may be outdated / May not fit the specific research question exactly / Bias in original collection.

19. (a) [1 mark]

  • Evidence of commodification (e.g., Traditional dances performed only for money, loss of authentic meaning).

19. (b) [1 mark]

  • Evidence of preservation (e.g., Restoration of heritage buildings funded by tourism revenue, revival of traditional crafts).

20. (a) [1 mark]

  • Example: "Recycling bins located near the canteen are used more frequently than those in the library." Must be testable.

20. (b) [2 marks]

  • 1 mark: Method (e.g., Observation count).
  • 1 mark: Detail (e.g., "Count the number of items in each bin at the end of the school day for one week.").
