Topic: Map, Graph & Data Skills

Section A: Map and Photograph Interpretation (15 Marks)

1. Map Extract 1 Analysis

(a) Grid Reference: [1 mark]
- Accept 4-digit grid reference for the lighthouse (e.g., 4522 or similar depending on specific insert logic, but typically 4-figure is accepted unless 6-figure requested. Based on prompt pattern, 4-figure is standard for quick ID).
- Marker Note: Ensure the candidate identifies the correct symbol.
(b) Distance Measurement: [1 mark]
- Answer must be within ±0.1 km of the actual measured distance on the specific insert.
- Marker Note: Check if scale line was used correctly.
(c) Settlement Pattern: [2 marks]
- 1 mark for identifying the pattern (e.g., linear, nucleated, dispersed).
- 1 mark for evidence/description (e.g., "houses are built along the main road" for linear).

2. Photograph A Analysis

(a) Landform ID: [1 mark]
- Correct identification (e.g., Stack, Arch, Cave, or Headland depending on Insert). Let's assume Stack for this key.
(b) Visible Features: [2 marks]

  - Presence of wave-cut notch.
(c) Formation Explanation: [3 marks]
- 1 mark for process: Hydraulic action/abrasion attacks weaknesses (cracks/joints).
- 1 mark for development: Crack enlarges to form cave, then arch, then collapses to form stack.
- 1 mark for link to photo: Reference to specific feature in photo (e.g., "As seen in the photo, the base is narrower...").

3. Resort Location Explanation: [5 marks]

Level 1 (1-2 marks): Generic statement about tourism.
Level 2 (3-4 marks): Links map features to resort location but lacks detail.
Level 3 (5 marks): Detailed explanation using map evidence.
- Points may include:
  - Proximity to beach/scenic area (aesthetic value).
  - Flat land (contour lines widely spaced) allows for easy construction.
  - Access to road network (transport links for tourists).
  - Sheltered bay (calm waters for water sports).
- Award 1 mark per valid point, up to 5. Must reference map.

Section B: Graph Construction and Data Representation (15 Marks)

4. Pie Chart Construction

(b) Driest Quarter: [1 mark]
- June, July, August (or any consecutive 3 months with lowest total, J-J-A is 290mm, M-A-M is 350mm).
(c) Plotting: [5 marks]
- 2 marks for correct plotting of rainfall bars (all 12 months correct).
- 2 marks for correct plotting of temperature line (all 12 points correct and joined).
- 1 mark for correct axis labels and units (°C and mm).

6. Climate Type Identification: [2 marks]

Name: Equatorial / Tropical Rainforest Climate. [1 mark]
Reason: High temperature year-round AND high rainfall year-round (no distinct dry season). [1 mark]

Section C: Statistical Analysis and Fieldwork Data (20 Marks)

7. Pedestrian Count Data

(a) Mean Calculation: [2 marks]
- Working: $(120 + 95 + 60 + 30 + 15) / 5$
- Sum = 320.
- Mean = $320 / 5 = 64$ .
- Answer: 64.
(b) Relationship Description: [2 marks]
- 1 mark for direction: Negative correlation / As distance increases, footfall decreases.
- 1 mark for qualification: It is a strong relationship / It decreases rapidly at first then levels off.
(c) Scatter Graph:
- (i) Axes: [2 marks]
  - X-axis: Distance from City Centre (Independent Variable).
  - Y-axis: Pedestrian Count (Dependent Variable).
- (ii) Appropriateness: [2 marks]
  - 1 mark for stating it shows relationship/correlation between two continuous variables.
  - 1 mark for explaining it helps identify trends/outliers.

8. River pH Levels

(a) Range Calculation: [1 mark]
- Max (6.8) - Min (6.5) = 0.3.
(b) Reason for Trials: [1 mark]
- To identify anomalies / increase reliability / calculate a more accurate mean.
(c) Hypothesis Evaluation: [4 marks]
- Level 1 (1 mark): States data supports hypothesis.
- Level 2 (2-3 marks): Uses data to support (pH drops from 7.2 to 5.9) but lacks critical evaluation.
- Level 3 (4 marks): Balanced evaluation.
  - Support: Data shows clear decrease in pH (increase in acidity) from Upstream (7.2) to Downstream (5.9). This aligns with the idea of pollution accumulation.
  - Limitation: Data alone does not prove industrial discharge is the cause (could be agricultural runoff or natural geology).
  - Conclusion: Data supports the trend of decreasing quality, but further testing is needed to confirm the source.

9. Divided Bar Graph Analysis

(a) Land Use Changes: [2 marks]
- 1 mark per change. Examples:
  - Agriculture decreased significantly (from 60% to 20%).
  - Residential use increased (from 30% to 50%).

(b) Impacts: [4 marks]
- Social Impact (2 marks):
  - Positive: More housing available / better access to shops/services.
  - Negative: Loss of rural community lifestyle / potential congestion.
- Environmental Impact (2 marks):
  - Negative: Loss of green space/habitat / increased urban heat island effect / increased runoff/pollution.
  - Positive: (Less likely but possible) Brownfield redevelopment might clean up old sites.
- Award 2 marks for each well-explained impact.
