A-Level Geography H2 Quiz - Map Graph Data Skills: Answer Key

Total Marks: 40
Topic: Map Graph Data Skills


Section A: Map Reading and Classification

Q1 [2]
Answer: Köppen-Geiger zone Af (tropical rainforest).
Teaching note: Pahang shows temperatures 24–28°C all months (>18°C) and rainfall >100 mm every month (no dry month). Per Köppen rules, Af = tropical with no month below 60 mm rainfall.
Marking: 1 mark for naming Af (or tropical rainforest climate); 1 mark for correct justification using temp + rainfall data from figure.

Q2 [3]
Answer: Technique = Choropleth mapping (shading by value).
Strength: Easy to compare spatial patterns at a glance across regions.
Limitation: Hides variation within each administrative unit (assumes uniform value inside area).
Teaching note: Choropleth uses predefined areas shaded by data class. Common mistake: calling it dot map.
Marking: 1 for name, 1 for strength, 1 for limitation.

Q3 [3]
Answer: Grid ref = 032 024. Relief NE = steep slope (contours 20→80 m close together).
Teaching note: Six-figure grid: estimate easting 03.2, northing 02.4 → 032 024. Closely spaced contours = steep.
Marking: 1 for GR, 2 for describing steep relief with contour evidence.

Q4 [2]
Answer: Advantage – shows spatial contrast clearly between countries. Disadvantage – misleading if countries differ greatly in area (large country looks more important).
Marking: 1 each.

Q5 [2]
Answer: 14 dots × 5 = 70 plants.
Teaching note: Dot maps use legend scale. Multiply count by scale.
Marking: 1 for 14×5, 1 for 70.

Q6 [2]
Answer: Bearing ≈ 045° (north-east).
Teaching note: Measure angle clockwise from north grid line to line A–B.
Marking: 2 for correct bearing ±5°.

Q7 [2]
Answer: Slump (rotational slide).
Teaching note: Curved failure surface and rotated block = slump, not fall or flow.
Marking: 2 for correct type.


Section B: Graph and Data Interpretation

Q8 [3]
Answer: Structure: emergent (~40 m), continuous canopy (25–30 m), understory (10 m), ground (<5 m). Mean biomass = 350 t/ha.
Teaching note: Describe all vertical layers, not just canopy. Biomass from table.
Marking: 2 for layers, 1 for biomass value.

Q9 [5]
Answer: City C highest total (175); City D lowest (115). City A leads economic (62) but weak environmental (48); City B strong environmental (70) but low economic (40); City C balanced high social (68).
Teaching note: Compare across cities and dimensions with comparative language.
Marking: 1 for highest/lowest, 4 for valid comparisons across dimensions (1 each dimension or paired contrast).

Q10 [3]
Sum = 20+18+25+30+42+55+60+58+45+35+28+22 = 438 m³/s.
Mean = 438 ÷ 12 = 36.5 m³/s.
Teaching note: Add all months, divide by 12. Units essential.
Marking: 1 sum, 1 division, 1 answer+unit.

Q11 [4]
Answer: (1) High birth rate / youthful population (wide base). (2) Low life expectancy / small elderly cohort (rapid narrowing).
Teaching note: Pyramid shape indicates stage 2 demographic transition.
Marking: 2 per characteristic with evidence from graph.

Q12 [3]
Answer: Proportional symbol = size of symbol shows magnitude at point/location; choropleth = shading of areas by average value. For oil: symbol size per country vs shaded area. Strength of proportional: shows actual volume; limitation: overlap in dense areas.
Marking: 1 diff, 1 strength, 1 limitation.

Q13 [3]
Answer: Positive correlation. Reason: CO₂ traps heat → rising concentrations increase anomaly.
Marking: 1 correlation, 2 for reasoned explanation.

Q14 [2]
Runoff coefficient = (360 ÷ 1200) × 100 = 30%.
Teaching note: Ratio of runoff to rainfall ×100.
Marking: 1 calc, 1 answer.


Section C: Integrated Data Skills

Q15 [4]
Answer: Zone = Af. Limitation: Map alone shows only latitude, not rainfall seasonality/temp range needed for full classification.
Marking: 2 for zone, 2 for limitation with reasoning.

Q16 [3]
Answer: Technique = Isoline (isohyet) map. Strength: shows gradual spatial change. Limitation: interpolation between points may be inaccurate.
Marking: 1 name, 1 strength, 1 limitation.

Q17 [5]
Answer: Japan highest internet (91) and mobile (98); India lowest internet (47) but mobile 79; Vietnam mid (68, 85). Gap internet Japan–India = 44 pts; mobile gap = 19 pts.
Marking: 1 highest/lowest, 4 for cross-country comparison.

Q18 [4]
Answer: Highest = Agriculture (45%). Lowest = Forestry (15%). Difference = 30 percentage points.
Teaching note: % difference = 45–15 = 30. Not relative %.
Marking: 1 highest, 1 lowest, 2 for calc.

Q19 [3]
Answer: Place line across coast; sample landforms at intervals; compare elevation/type along transect to show change.
Marking: 1 line, 1 sampling, 1 analysis.

Q20 [3]
Answer: Output = map of population in high flood risk zones. Limitation = data resolution may miss local variation; correlation ≠ causation.
Marking: 1 output, 2 for limitation reasoned.
