Answers
O-Level Geography Quiz - Physical Geography (Answer Key)
Total Marks: 40
Topic: Physical Geography
Section A: Answers
Q1 [1 mark]
Answer: London has a larger annual temperature range than Singapore (or Singapore temperatures are more constant around 26–28°C while London varies from 5°C to 22°C).
Teaching note: Temperature pattern refers to how temperature changes across months. Singapore is near equator → small range; London mid-latitude → seasonal variation. Accept any one clear difference.
Q2 [3 marks]
Answer: Use a bar chart (or grouped bar chart) with locations A, B, C on x-axis and wind speed (km/h) on y-axis; OR a line graph if time-series but here comparison → bar chart best. Include legend/labels.
Mark breakdown: 1 mark for graph type (bar chart), 1 mark for correct axes (location, wind speed with unit), 1 mark for labelling/legend.
Teaching note: Continuous comparison of 3 categories → bar chart. Do not use pie chart (not for comparing magnitudes across independent sites). Common mistake: suggesting 3 separate graphs.
Q3 [1 mark]
Answer: Wave-cut platform.
Teaching note: Flat eroded surface at cliff base formed by wave action.
Q4 [2 marks]
Answer: Any one feature e.g., "The cliff is steep/vertical" (1m), "approximately 20 m high with bare rock" (1m).
Mark breakdown: 1 mark identify feature, 1 mark elaboration (height/material/gradient).
Teaching note: Describe = what you see, not process.
Q5 [1 mark]
Answer: Volcanoes are concentrated along the plate boundary (linear pattern).
Teaching note: Map shows dots on boundary line, not random.
Q6 [2 marks]
Answer: 120 + 90 + 60 + 40 = 310 mm.
Working: Jan 120, Feb 90 → 210; + Mar 60 → 270; + Apr 40 → 310.
Teaching note: Sum bars from chart. Units must be mm.
Q7 [1 mark]
Answer: Evaporation.
Teaching note: Upward arrow from ocean to cloud = water turning to vapour.
Q8 [1 mark]
Answer: Burning fossil fuels (or deforestation, cement production).
Teaching note: Releases CO₂, traps heat.
Section B: Answers
Q9 [3 marks]
Answer: Waves attack cliff base at high tide → notch forms (1m). Undercutting causes cliff to collapse (1m). Repeated retreat leaves flat platform at low tide level (1m).
Teaching note: Process = erosion + mass movement. Link to Q3 photo.
Q10 [2 marks]
Answer: High annual rainfall (e.g., >2000mm) (1m); high and stable temperatures (~25–28°C) (1m).
Teaching note: Tropical climate near equator; not four seasons.
Q11 [3 marks]
Answer: Longshore drift moves sediment along coast (1m); at a bend or river mouth, deposition occurs (1m); sediment extends as narrow ridge into sea = spit (1m).
Teaching note: Spit = depositional, needs drift + supply.
Q12 [2 marks]
Answer: Add the recorded temperatures for each location; divide by number of recordings (1m). Example: (T1+T2+...)/n (1m).
Teaching note: Mean = sum ÷ count. Not just state highest.
Q13 [2 marks]
Answer: Weather = short-term atmospheric condition (1m); climate = long-term average over 30+ years (1m).
Teaching note: Time scale is key difference.
Q14 [3 marks]
Answer: Boundary is convergent (1m); one plate subducts, melts to magma (1m); magma rises to form volcanoes on boundary (1m).
Teaching note: From Q5 map, volcanoes on edge = subduction zone.
Q15 [2 marks]
Answer: Any two: sea level rise floods land (1m); stronger storms erode coast (1m).
Teaching note: Climate change → thermal expansion + ice melt.
Section C: Answers
Q16 [5 marks]
Describe (2m): Steep rocky cliff ~20m; wave-cut platform flat ~10m wide at base.
Account (3m): Wave erosion at high tide cuts notch; cliff collapses; repeated retreat forms platform; process visible in photo.
Teaching note: Must link photo. Mark descriptors: 2 for description, 3 for process with mechanism.
Q17 [4 marks]
Position: Partially unreliable (1m). Evidence: single quadrat = small sample (1m); one time = misses tidal variation (1m); but quick method reduces cost (1m).
Teaching note: Reliability = consistency. Counterargument needed for 4th mark.
Q18 [4 marks]
Cause: CO₂/methane trap infrared (1m); from fossil fuels/deforestation (1m). Leads to: more heat retained → global temp rise (1m); melting ice, sea rise (1m).
Teaching note: Greenhouse effect natural but enhanced by humans.
Q19 [4 marks]
Natural processes dominate (1m): plate movement, earthquakes (1m). Human action minor (1m): mining, dams induce small quakes but not main (1m). Conclusion: mostly natural.
Teaching note: Evaluate = weigh both, conclude.
Q20 [4 marks]
Against sustainable: hard engineering, high cost, visual impact (1m). For: protects lives/properties now (1m). Not fully sustainable: no long-term ecosystem benefit (1m); better soft engineering (1m).
Teaching note: Sustainable = meet present without compromising future.
