O-Level Geography Quiz - Map Graph Data Skills (Answer Key)

Total Marks: 40

Section A: Graphical Representation and Interpretation

1. Describe the trend in rainfall from January to July. [2]

  • Marking Scheme:
    • 1 mark for stating the general trend (decreasing/falling).
    • 1 mark for supporting data evidence (e.g., from 240mm to 90mm).
  • Answer: Rainfall decreases steadily from January (240mm) to July (90mm).

2. Calculate the range in temperature for the year. Show your working. [2]

  • Marking Scheme:
    • 1 mark for correct identification of max/min (31°C and 25°C).
    • 1 mark for correct calculation (6°C).
  • Answer:
    • Max Temp: 31°C (June)
    • Min Temp: 25°C (Dec)
    • Range: 31−25=6∘C31 - 25 = 6^\circ\text{C}

3. Suggest the most appropriate graph type... Explain why. [3]

  • Marking Scheme:
    • 1 mark for "Climate Graph" or "Combined Bar and Line Graph".
    • 1 mark for identifying Rainfall as bars.
    • 1 mark for identifying Temperature as a line.
    • Alternative: 1 mark for explaining that it allows comparison of two different units (mm and °C) on the same time axis.
  • Answer: A climate graph (compound bar and line graph). Rainfall is shown as bar charts because it is cumulative/quantity, while temperature is shown as a line graph to show the continuous trend/change over time. This allows easy comparison of seasonal patterns.

4. Identify the month with the highest rainfall and the month with the lowest temperature. [2]

  • Answer:
    • Highest Rainfall: December (250mm)
    • Lowest Temperature: December (25°C)

5. Evaluate the statement: "Higher temperatures cause lower rainfall." [3]

  • Marking Scheme:
    • 1 mark for stating agreement or disagreement (Disagree/Partially Agree).
    • 1 mark for evidence supporting the view (e.g., June is hottest and dry).
    • 1 mark for evidence contradicting the view or nuance (e.g., Dec/Jan are cool but wettest; correlation does not equal causation).
  • Answer: The statement is partially supported but not entirely accurate. While the hottest month (June, 31°C) has the lowest rainfall (90mm), the coolest months (Dec/Jan, 25-26°C) have the highest rainfall. This suggests an inverse relationship in this specific dataset, but "cause" cannot be proven by this data alone; it may be due to monsoon seasons rather than temperature directly causing dryness.

Section B: Map Reading and Spatial Analysis

6. Calculate actual ground distance between X and Y. [2]

  • Marking Scheme:
    • 1 mark for conversion formula (4 cm×50,0004 \text{ cm} \times 50,000).
    • 1 mark for correct answer in km (2 km).
  • Answer:
    • 4 cm×50,000=200,000 cm4 \text{ cm} \times 50,000 = 200,000 \text{ cm}
    • 200,000÷100,000=2 km200,000 \div 100,000 = 2 \text{ km}

7. Calculate the gradient between X and Y. [3]

  • Marking Scheme:
    • 1 mark for height difference (45−5=40m45 - 5 = 40\text{m}).
    • 1 mark for horizontal distance in same units (2 km=2000m2 \text{ km} = 2000\text{m}).
    • 1 mark for correct ratio (1:501:50).
  • Answer:
    • Rise: 45m−5m=40m45\text{m} - 5\text{m} = 40\text{m}
    • Run: 2 km=2000m2 \text{ km} = 2000\text{m}
    • Gradient: 402000=150\frac{40}{2000} = \frac{1}{50} or 1:501:50

8. Describe the relief... [3]

  • Marking Scheme:
    • 1 mark for steepness (steep slope).
    • 1 mark for evidence (contours are close together).
    • 1 mark for direction/shape (slope rises from SW to NE / convex/concave if visible, or just "uniform slope").
  • Answer: The relief is steep. This is evidenced by the contour lines being close together between the grid references. The land rises from 5m to 45m over a short horizontal distance.

9. Direction from Z to Y. [1]

  • Answer: North (or North-North-East depending on precise grid orientation, but typically North if 1236 to 1436 implies Easting change? Wait. Z=1236, Y=1436. Easting 12->14 is East. Northing 36->36 is same. So Z to Y is East. Correction based on standard grid logic: First 2 digits Easting, last 2 Northing. Z(12,36) to Y(14,36). Change in Easting only. Direction is East.)
    • Self-Correction in Question Design: Let's assume standard 4-figure. Z(1236) is East 12, North 36. Y(1436) is East 14, North 36. Direction is East.

10. Evidence of river flow direction. [1]

  • Answer: Contour lines form V-shapes pointing upstream (towards Y/higher ground) or the elevation decreases from Y (45m/High) to Z (10m/Low/Mouth).

Section C: Statistical Analysis and Data Processing

11. Calculate mean Dissolved Oxygen. [2]

  • Marking Scheme:
    • 1 mark for sum (29.6).
    • 1 mark for division by 5 (5.92).
  • Answer:
    • Sum: 8.5+7.0+4.2+3.1+6.8=29.68.5 + 7.0 + 4.2 + 3.1 + 6.8 = 29.6
    • Mean: 29.6÷5=5.92 mg/L29.6 \div 5 = 5.92 \text{ mg/L}

12. Site with highest pollution (Nitrate). [1]

  • Answer: Site 4 (18.5 ppm)

13. Relationship between Distance and Nitrate (Site 1-4). [2]

  • Marking Scheme:
    • 1 mark for trend (positive correlation/increases).
    • 1 mark for detail (as distance increases, nitrate levels rise).
  • Answer: There is a positive correlation. As the distance from the source increases from 2km to 12km, nitrate levels increase significantly from 2.0ppm to 18.5ppm.

14. Why Site 5 is different. [2]

  • Marking Scheme:
    • 1 mark for identifying dilution/aeration/tributary.
    • 1 mark for explanation.
  • Answer: Site 5 may be further downstream where the river widens and aerates (increasing Oxygen), or a clean tributary has joined, diluting the nitrate concentration. Alternatively, pollution sources may have ceased after Site 4.

15. Limitation of Visual Clarity Score. [2]

  • Marking Scheme:
    • 1 mark for identifying subjectivity.
    • 1 mark for explanation (bias/lighting conditions).
  • Answer: The data is subjective. Different students may interpret "clarity" differently, leading to inconsistent results. Lighting conditions (time of day) can also affect visibility, reducing reliability.

Section D: Fieldwork Data Evaluation and Synthesis

16. Scatter graph position for C. [2]

  • Answer: Location C would be in the bottom-left corner of the graph (Low Pedestrian Count, Low Litter Volume).

17. Percentage increase in pedestrian count from C to A. [3]

  • Marking Scheme:
    • 1 mark for difference (480).
    • 1 mark for division by original (20).
    • 1 mark for correct percentage (2400%).
  • Answer:
    • Difference: 500−20=480500 - 20 = 480
    • 48020×100=2400%\frac{480}{20} \times 100 = 2400\%

18. Is the hypothesis supported? [3]

  • Marking Scheme:
    • 1 mark for Yes/Supported.
    • 1 mark for evidence from A vs C.
    • 1 mark for evidence from B (intermediate).
  • Answer: Yes, the hypothesis is supported. Location A has the highest pedestrians (500) and highest litter (12kg). Location C has the lowest pedestrians (20) and lowest litter (1kg). Location B is intermediate for both. This shows a direct positive correlation.

19. Evaluate reliability of Sunday morning data. [3]

  • Marking Scheme:
    • 1 mark for identifying temporal bias.
    • 1 mark for explanation (weekend vs weekday).
    • 1 mark for suggestion (need repeated samples).
  • Answer: The data is not fully reliable because it was collected only on a Sunday. Visitor numbers and litter generation may be significantly higher on weekends than weekdays. To improve reliability, data should be collected on different days of the week and at different times of the day to get a representative average.

20. Alternative method to measure impact. [2]

  • Answer:
    • Method: Environmental Quality Survey (EQS) using a bipolar scale.
    • Detail: Score factors like noise levels, smell, or vegetation damage on a scale of -3 to +3.
    • OR: Photographic evidence comparison over time.
