TuitionGoWhere Practice Paper Answer Key — Geography O-Level (Version 2)
Subject: Geography
Level: O-Level
Paper: Practice Paper (Map Graph Data Skills)
Total Marks: 50
Section A Answers (12 marks)
Q1 [3 marks]
- Suggestion: Use a line graph or grouped bar chart with months on x-axis and temperature on y-axis, one line/bar group per station. [1]
- Justification: Allows direct comparison of trends across four stations on one graph. [1]
- Requirement: Label axes (months, °C), include legend for stations. [1]
Teaching note: Continuous data over time → line graph; categorical comparison → bar. Avoid separate graphs (common trap).
Q2 [2 marks]
Mean = (1200 + 1500 + 1800) ÷ 3 = 4500 ÷ 3 = 1500 visitors. [2 for correct calc]
Working: Sum = 4500; ÷3 = 1500.
Q3 [1 mark]
Advantage: Shows spatial pattern/location at a glance (e.g., clustering, distribution) which table cannot. [1]
Q4 [2 marks]
- Suitable graph: Bar chart. [1]
- Labelling: Title, x-axis "Site", y-axis "Noise level (dB)", bars labelled A/B/C. [1]
Q5 [1 mark]
East (240 mm). [1]
Q6 [3 marks]
Positive score = (10×2) + (5×1) = 20 + 5 = 25. [1]
Negative score = (3×1) + (2×2) = 3 + 4 = 7. [1]
Net method: Multiply frequency by weight, sum positives and negatives separately. [1]
Section B Answers (20 marks)
Q7 [2 marks]
Temperature rises from 26°C (Jan) to 29°C (Jul) [1]; generally increasing trend with peak mid-year. [1]
Q8 [3 marks]
Station X mean = (26+27+28+28+29+29+29+29+28+28+27+26)÷12 = 336÷12 = 28.0°C. [1]
Station Y mean = (25+26+27+27+28+28+28+28+27+27+26+25)÷12 = 318÷12 = 26.5°C. [1]
Difference = 28.0 – 26.5 = 1.5°C. [1]
Q9 [1 mark]
Slices must sum to 100% (or 360°) of circle. [1]
Q10 [1 mark]
B is west (or northwest) of A (inland from coast, contour implies inland direction). [1]
Q11 [2 marks]
Contour lines show elevation and slope steepness [1]; closer lines = steeper slope, helping identify highlands/valleys. [1]
Q12 [2 marks]
Range = 4000 – 1000 = 3000 people/km². [2]
Q13 [3 marks]
Suggests air quality improves (index better) farther from city [1]; likely due to less traffic/industry [1]; spatial association between urban core and pollution. [1]
Section C Answers (18 marks)
Q14 [4 marks]
Position: Partially reliable. [1]
Evidence: Small sample (20 students) limits representativeness. [1]
Method: Likert scale gives quantifiable scores, structured. [1]
Qualification: Could be reliable for that school but not generalisable. [1]
Q15 [6 marks]
Effective: Systematic distances reduce bias. [1] Tally is simple, low cost. [1]
Limitations: 10 min may miss peak hours. [1] No repeat days. [1] Only one road? [1]
Conclusion: Partially effective; improve with longer count, multiple days. [1]
Q16 [5 marks]
GIS overlays land cover, built-up, temperature sensors. [2]
Adv: Visualises hotspots, processes data fast. [1]
Limit: Needs accurate input, training. [1]
(Structure: use+adv+limit = 5)
Q17 [4 marks]
Total rain = 100+80+120+150+200+180+190+210+160+140+110+90 = 1730 mm. [2]
Temp: Stable around 26–28°C, small variation. [2]
Q18 [3 marks]
Only one period shown [1]; "always" needs long-term data [1]; West may vary seasonally. [1]
Q19 [2 marks]
Dot map of litter locations [1]; heat map of density. [1]
Q20 [4 marks]
Mean S1 = (12+15)÷2 = 13.5 km/h. [2]
Graph: Grouped bar chart (sites on x, days as groups) or line graph. [2]
