A-Level Geography H2 Quiz - Fieldwork: Answer Key
Total Marks: 40
Topic: Fieldwork (Cluster 4, Syllabus 9173)
Section A Answers (Q1–8)
Q1 [1 mark]
Answer: To collect primary data / test hypotheses in real-world settings / develop geographical skills.
Teaching note: Fieldwork bridges theory and observation; any one valid purpose accepted.
Q2 [1 mark]
Answer: Stream gauging / quadrat sampling / transect walk / tape measure width.
Teaching note: Primary methods are researcher-directed; not secondary sources.
Q3 [2 marks]
Answer: (1) Informed consent from residents; (2) anonymise responses.
Marking: 1 mark per valid ethical point.
Teaching note: Ethics protect participants and data integrity.
Q4 [2 marks]
Advantage: Direct, cheap, simple. Limitation: Limited to accessible points, operator error.
Marking: 1m each.
Q5 [1 mark]
Answer: Primary data.
Q6 [4 marks]
Forest: Avoid trampling, stay on paths, no sample removal.
Urban canal: Avoid contamination, safe edge, permission for access.
Marking: 2m each site, differ meaningfully.
Q7 [3 marks]
Technique: Grid mapping / stratified sampling grid.
Strength: Systematic, comparable. Limitation: Ignores variation within cell.
Marking: 1+1+1.
Q8 [2 marks]
Working: (6.2+6.8+7.1+6.5+7.0)/5 = 33.6/5 = 6.72
Mean: 6.72
Marking: 1m working, 1m answer.
Section B Answers (Q9–14)
Q9 [3 marks]
Answer: Four layers; emergent 35m/40t, canopy 22m/120t, understory 8m/25t, ground 1m/5t; total 190 t/ha.
Marking: Structure 1m, biomass values 1m, synthesis 1m.
Q10 [3 marks]
Answer: Rises from 5 to peak 140 at 6h, then falls to 10 by 12h; lagged response.
Marking: Rise 1m, peak 1m, fall 1m.
Q11 [2 marks]
Answer: Increased overland flow after saturation mobilises sediment.
Marking: Process + link to graph.
Q12 [2 marks]
Answer: Pilot test, larger sample, standardised questions.
Marking: 1m each.
Q13 [5 marks]
Answer: C highest (21), A (18), D (16), B lowest (15). C strong green/clean; B noisy.
Marking: Compare across all 4 with numbers, 1m each dimension referenced.
Q14 [2 marks]
Hazard: Slump / translational slide. Precaution: Keep distance, helmet.
Marking: 1+1.
Section C Answers (Q15–20)
Q15 [6 marks]
Answer: Stratified sites upstream/downstream; measure width, depth, velocity; repeat 3x; use GPS.
Marking: Design 2m, sampling 2m, variables 2m.
Q16 [4 marks]
Strengths: Visual, layered. Limits: Skill needed, data errors.
Marking: 2+2.
Q17 [8 marks]
L1 (1–2): Simple, partial. L2 (3–5): Some representation, limits noted. L3 (6–8): Synthesises scale, time, control; balanced judgement.
Content: School scope vs real complexity; use of proxies; cannot replicate climate events.
Q18 [3 marks]
Working: (29.5-28.0)/8m *100 = 18.75°C/100m (inversion).
Rate: 18.75°C/100m. Interpretation: Temperature increases with height (inversion).
Marking: 1+1+1.
Q19 [5 marks]
Interviews: Depth, flexible. Questionnaires: Scale, comparable. Evaluate trade-off.
Marking: 2+2+1 conclusion.
Q20 [5 marks]
Assess: Tropical hazards (storm, disease); legal, safety, contingency.
