A-Level Geography H1 Quiz - Map Graph Data Skills (Answer Key)
Total Marks: 40
Topic: Map, Graph & Data Skills
Section A: Data Reading
1. [1 mark]
Answer: 0.9 million (or 900,000).
Working: 3.4 – 2.5 = 0.9.
Teaching note: Absolute increase = final − initial. Common mistake: writing 0.9% instead of million.
2. [1 mark]
Answer: January.
Reason: 120 mm > 20 mm.
Teaching note: Taller bar = more precipitation.
3. [1 mark]
Answer: 20 m.
Reason: 60 − 40 = 20 m, equals one contour interval.
Teaching note: Contour interval is constant difference in elevation.
4. [1 mark]
Answer: 55% (or 0.55).
Working: 100% − 45% = 55%.
Teaching note: Whole = 100%.
5. [1 mark]
Answer: Positive correlation.
Teaching note: Points rising left to right = as one variable increases, other increases.
Section B: Graph and Map Interpretation
6. [2 marks]
Answer: July, 240 mm. [1 for month, 1 for value]
Teaching note: Read peak from line graph.
7. [2 marks]
Working: (80 + 70 + 90) ÷ 3 = 240 ÷ 3 = 80 mm.
Answer: 80 mm. [1 for sum, 1 for mean]
Teaching note: Mean = total ÷ number of months.
8. [2 marks]
Answer: Town R, 55%. [1 each]
Teaching note: Tallest bar = highest rate.
9. [1 mark]
Answer: River / water body.
Teaching note: Blue line = surface water on maps.
10. [1 mark]
Answer: District C.
Teaching note: Darkest shade = highest density class.
11. [2 marks]
Answer: One limitation: choropleth shows grouped classes, not exact values; e.g., all districts in 300–600 class look same though densities differ. [2 for explanation]
Teaching note: Mention loss of precision.
12. [2 marks]
Working: (150 − 90) ÷ 90 × 100 = 60 ÷ 90 × 100 = 66.7%.
Answer: 66.7% increase. [1 working, 1 answer]
Teaching note: % increase = (new−old)/old ×100.
13. [1 mark]
Answer: Elderly (already given as 5%); if asking missing, total 100% so none missing. If interpreted as category not labelled: elderly.
Teaching note: 40+55+5=100.
Section C: Data Representation and Evaluation
14. [2 marks]
Answer: Bar chart. Reason: compares discrete categories (neighbourhoods) easily. [1 + 1]
Teaching note: Bar for categorical comparison.
15. [2 marks]
Answer: x-label: Neighbourhood; y-label: % elderly (0–25). Bars: N1 14, N2 18, N3 22, N4 11, N5 19. [1 labels, 1 heights]
Teaching note: Sketch must show correct scale.
16. [3 marks]
Mark descriptors:
- 1 mark: dot map shows location of points.
- 2 marks: useful to see spatial pattern of flood depth.
- 3 marks: limitation – does not show depth value clearly without size/colour scale; ruler data may have error ±cm.
Answer: Useful for spatial distribution but limited by lacking precise depth legend.
Teaching note: Evaluate = strength + weakness.
17. [4 marks]
Mark breakdown:
- R1 satellite: visual extent of expansion, landuse change (2)
- R2 table: numerical growth, trend (1)
- Limitation: image no dates; table no location (1)
Answer: Both useful together; image shows where, table shows how much.
Teaching note: Use both sources, weigh.
18. [2 marks]
Answer: Trend: steady rise from 0.0 to 0.8 °C. Positive anomaly = warmer than baseline. [1 +1]
Teaching note: Anomaly = deviation from average.
19. [2 marks]
Working: Subtract 1950 value from 2020: 0.8 − 0.0 = 0.8 °C. [2]
Teaching note: Total rise = final − initial.
20. [2 marks]
Answer: Advantage: shows proportion of annual rain per month. Disadvantage: hard to read exact mm, 12 slices cramped. [1+1]
Teaching note: Pie for parts of whole.
