Section A: Map Skills and Grid References (Questions 1–5)
1. State the 4-figure grid reference of the school located in the south-western part of the map extract. [1]
Answer: 3152
Marking: 1 mark for correct 4-figure grid reference.
Note: Read eastings (horizontal) first, then northings (vertical). Common error: reversing the order to 5231.
2. What is the six-figure grid reference of the bridge that crosses the river at the lowest point of the valley? [2]
Answer: 345562
Marking:
- 1 mark for correct easting (345)
- 1 mark for correct northing (562)
Note: For six-figure references, estimate the position within the grid square to one-tenth. The third and sixth digits represent this estimation.
3. State the compass direction of the hospital from the police station. [1]
Answer: South-east
Marking: 1 mark for correct compass direction.
Note: Draw an arrow from the reference point (police station) to the target (hospital). Common error: stating the direction of the police station from the hospital instead.
4. The temple in grid square 3456 is located on a hillside. State the straight-line distance (in kilometres) between the temple and the school in grid square 3152. Use the scale provided. [2]
Answer: 3.5 km
Marking:
- 1 mark for measuring the correct distance on the map (7 cm)
- 1 mark for converting using the scale (1:50,000 → 7 cm × 0.5 km/cm = 3.5 km)
Working: - Measure distance on map: 7 cm
- Scale: 1 cm = 0.5 km
- Calculation: 7 × 0.5 = 3.5 km
Note: Common error: forgetting to convert centimetres to kilometres using the scale.
5. Identify the type of land use found in grid square 3355. Give one piece of map evidence to support your answer. [2]
Answer: Residential / Housing
Evidence: Presence of closely spaced buildings / road network / housing symbols
Marking:
- 1 mark for correct land use identification
- 1 mark for valid map evidence
Note: Accept any reasonable land use with supporting evidence from map symbols.
Section B: Contour Interpretation and Relief (Questions 6–10)
6. What is the contour interval of the map extract? [1]
Answer: 20 metres
Marking: 1 mark for correct contour interval.
Note: The contour interval is the difference in height between two adjacent contour lines. Common error: stating the height of a single contour line instead of the interval.
7. Describe the shape of the land in grid square 3658. Use evidence from the contour lines in your answer. [2]
Answer: The land is a hill / high ground. The contour lines form closed circles with values increasing towards the centre (e.g., 100 m, 120 m, 140 m).
Marking:
- 1 mark for identifying the landform (hill/high ground)
- 1 mark for evidence (closed contours / increasing values towards centre)
Note: Accept "mountain" or "peak" if supported by evidence.
8. Grid square 3759 shows a ridge. State two pieces of evidence from the contour lines that support this. [2]
Answer:
- Contour lines form elongated high ground (not closed circles).
- Contour lines are closely spaced on the sides but wider along the top.
Marking: 1 mark for each valid piece of evidence (2 marks total).
Note: A ridge is different from a hill — it is a long, narrow elevated landform.
9. Calculate the gradient of the slope between Point A (height 120 m) and Point B (height 80 m). The horizontal distance between the two points is 400 m. Show your working. [3]
Answer: 1:10 (or 0.1)
Working:
- Vertical difference (height): 120 m − 80 m = 40 m
- Horizontal distance: 400 m
- Gradient = Vertical difference ÷ Horizontal distance
- Gradient = 40 ÷ 400 = 0.1
- Expressed as ratio: 1:10
Marking: - 1 mark for correct vertical difference (40 m)
- 1 mark for correct formula application
- 1 mark for final answer (1:10 or 0.1)
Note: Common error: dividing horizontal distance by vertical difference (inverted gradient).
10. A hiker wants to take the easiest route from Point X to Point Y. Which route should they choose and why? Refer to the contour pattern in your answer. [3]
Answer: The hiker should choose the route where contour lines are most widely spaced. Widely spaced contour lines indicate a gentle slope, which is easier to walk on.
Marking:
- 1 mark for identifying the correct route (widely spaced contours)
- 1 mark for explaining that widely spaced contours = gentle slope
- 1 mark for linking gentle slope to easier walking
Note: Closely spaced contours indicate steep slopes, which are harder to traverse.
Section C: Graph and Data Interpretation (Questions 11–15)
11. Which month recorded the highest rainfall? State the month and the rainfall amount. [2]
Answer: November; 280 mm
Marking:
- 1 mark for correct month (November)
- 1 mark for correct rainfall amount (280 mm)
Note: Common error: stating only the month without the value, or misreading the scale.
12. Calculate the total rainfall for the months of June, July, and August. Show your working. [2]
Answer: 450 mm
Working:
- June: 120 mm
- July: 180 mm
- August: 150 mm
- Total: 120 + 180 + 150 = 450 mm
Marking: - 1 mark for correct values read from the graph
- 1 mark for correct total (450 mm)
Note: Common error: misreading bar heights or making addition errors.
13. Describe the trend in rainfall from January to December. Identify any patterns you observe. [3]
Answer: Rainfall is lowest in the first quarter (January–March), increases gradually through the middle months, and peaks in November before dropping again in December. There is a wet season from September to November and a dry season from January to March.
Marking:
- 1 mark for identifying the general trend (increase then decrease)
- 1 mark for identifying the wet season / peak months
- 1 mark for identifying the dry season / low months
Note: Accept any valid pattern description supported by data from the graph.
14. What percentage of the total land area is used for agriculture? [1]
Answer: 35%
Marking: 1 mark for correct percentage.
Note: Read directly from the pie chart. Common error: confusing agriculture with another sector.
15. If the total area of Greenfield Valley is 250 km², calculate the area covered by forest. Show your working. [2]
Answer: 75 km²
Working:
- Forest percentage from pie chart: 30%
- Calculation: 30% × 250 km² = 0.30 × 250 = 75 km²
Marking: - 1 mark for correct percentage identified from pie chart (30%)
- 1 mark for correct calculation (75 km²)
Note: Common error: using the wrong percentage or forgetting to convert percentage to decimal.
Section D: Data Analysis and Application (Questions 16–20)
16. Which river has the highest dissolved oxygen level? What does this suggest about its water quality? [2]
Answer: River Gamma (9.0 mg/L). This suggests the water quality is good / healthy, as high dissolved oxygen supports aquatic life.
Marking:
- 1 mark for identifying River Gamma
- 1 mark for explaining that high dissolved oxygen = good water quality
Note: Dissolved oxygen above 6 mg/L is generally considered healthy for most aquatic organisms.
17. River Beta has a higher turbidity than River Gamma. Suggest two possible reasons for this difference. [2]
Answer:
- Soil erosion from nearby construction or deforestation is washing sediment into River Beta.
- Industrial discharge or agricultural runoff is adding particles to River Beta.
Marking: 1 mark for each valid reason (2 marks total).
Note: Accept any reasonable human or natural cause of increased turbidity.
18. Based on the data, which river is likely to be the healthiest aquatic ecosystem? Justify your answer using two pieces of evidence from the table. [3]
Answer: River Gamma is likely the healthiest.
Evidence:
- It has the highest dissolved oxygen (9.0 mg/L), which supports fish and other aquatic life.
- It has the lowest turbidity (8 NTU), meaning the water is clearer and allows sunlight to reach aquatic plants.
Marking:
- 1 mark for identifying River Gamma
- 1 mark for first piece of evidence with explanation
- 1 mark for second piece of evidence with explanation
Note: Accept River Alpha with valid justification, but River Gamma has the strongest evidence.
19. A student claims that the pH level of a river is the most important indicator of water quality. Do you agree? Explain your reasoning using evidence from the data. [3]
Answer: I partially agree / disagree. While pH is important (most aquatic life thrives at pH 6.5–8.5), it is not the only indicator. Dissolved oxygen and turbidity are equally important. For example, River Beta has a slightly acidic pH (6.3) but its low dissolved oxygen (5.4 mg/L) and high turbidity (45 NTU) are more serious problems. Therefore, we need to consider multiple indicators together.
Marking:
- 1 mark for stating a clear position (agree/disagree/partially agree)
- 1 mark for explaining the importance of pH
- 1 mark for using data to show other indicators matter too
Note: Accept any well-reasoned response supported by data.
20. The local council wants to improve water quality in River Beta. Suggest two strategies they could use and explain how each would help. [3]
Answer:
- Reduce agricultural runoff by creating buffer zones of vegetation along the river banks. This would filter out sediment and pollutants before they enter the water, reducing turbidity.
- Upgrade sewage treatment plants to reduce discharge of organic waste into the river. This would increase dissolved oxygen levels as less organic matter would decompose in the water.
Marking:
- 1 mark for first strategy with explanation
- 1 mark for second strategy with explanation
- 1 mark for linking strategies to specific water quality improvements
Note: Accept any reasonable strategy with a clear explanation of how it improves water quality.
