SA2 (Version 4 of 5) — Answer Key
Total Marks: 50
Section A: Map Reading Skills (15 marks)
1. Four-figure grid reference of the hospital: 1432 [1]
Marking note: Award 1 mark for the correct four-figure grid reference. Easting (14) must come before northing (32). Do not accept reversed answers (e.g., 3214).
2. Six-figure grid reference of the school: 162347 [1]
Working:
- Grid square easting: 16; northing: 34
- Two-tenths east → 2; seven-tenths north → 7
- Six-figure reference: 162347
Marking note: Award 1 mark for the correct six-figure reference. Common error: writing 167343 (reversing the tenths).
3. Compass direction of the church from the car park: North-East (NE) [1]
Working:
- Car park: 1331; Church: 1735
- Church is further east (17 > 13) and further north (35 > 31)
- Therefore, direction is north-east
Marking note: Accept "NE" or "north-east". Do not accept vague answers like "up and right".
4. Direction of river flow: [2]
Sample answer: The river flows from the north-west to the south-east of the map extract. [1] This is because the river begins in grid square 1236 (north-west area) and ends at 1731 (south-east area), showing it flows from higher ground in the north-west towards lower ground in the south-east. [1]
Marking note: Award 1 mark for correct direction (NW to SE or equivalent). Award 1 mark for map evidence (grid references or compass reasoning).
5. Straight-line distance from hospital to school: [2]
Working:
- Map distance = 8 cm
- Scale: 1 cm = 0.25 km (since 1:25,000 means 1 cm = 25,000 cm = 0.25 km)
- Actual distance = 8 × 0.25 = 2.0 km
Alternative method:
- 8 cm × 25,000 = 200,000 cm = 2 km
Answer: 2.0 km (or 2 km)
Marking note: Award 1 mark for correct method/working. Award 1 mark for correct final answer with unit. If the answer is correct but no working is shown, award 2 marks. If the method is correct but the final answer has a calculation error, award 1 mark.
6. Two types of land use in grid square 1535: [2]
(a) Woodland / Forest [1]
(b) Residential / Housing (or any other valid feature shown in that grid square, e.g., "road", "park") [1]
Marking note: Award 1 mark per correct land use identified. Answers must be consistent with the map provided. Accept any two distinct land uses visible in the grid square.
7. Route of the railway line: [3]
Sample answer: The railway line runs in an east–west direction across the map extract. [1] It begins in grid square 1333 on the western side and continues eastward through grid squares 1433, 1533, 1633, and ends at 1733 on the eastern side. [1] The railway line passes south of the hospital (1432) and north of the river as it crosses the map. [1]
Marking note: Award 1 mark for correct compass direction. Award 1 mark for accurate grid square references along the route. Award 1 mark for describing features the railway passes near or through. Maximum 3 marks.
8. Suitability of grid square 1636 for a housing estate: [2]
Reason it could be true: The area is relatively flat (or has existing road access / is near other residential areas), making construction easier and more cost-effective. [1]
Reason it could be false: The area contains woodland (grid squares 1535–1636), which would need to be cleared, raising environmental concerns and potentially increasing costs. Alternatively, the area may be flood-prone if it is near the river. [1]
Marking note: Award 1 mark for a valid reason supporting the statement and 1 mark for a valid reason against it. Reasons must be plausible and based on map evidence.
Section B: Graph and Data Interpretation (20 marks)
9. Total rainfall for June and July: [2]
Working:
- June rainfall = 130 mm
- July rainfall = 150 mm
- Total = 130 + 150 = 280 mm
Marking note: Award 1 mark for correct working (identifying both values). Award 1 mark for correct final answer with unit.
10. Month with highest rainfall: [2]
Month: July [1]
Rainfall: 150 mm [1]
Marking note: Both the month and the value must be correct for full marks.
11. Range of rainfall: [2]
Working:
- Highest rainfall = 150 mm (July)
- Lowest rainfall = 60 mm (February)
- Range = 150 − 60 = 90 mm
Marking note: Award 1 mark for identifying the correct highest and lowest values. Award 1 mark for correct final answer with unit.
12. Temperature trend from January to April: [2]
Sample answer: The average monthly temperature increased from January to April. [1] In January, the temperature was 26°C, and it rose steadily to reach 29°C in April, an increase of 3°C over the four-month period. [1]
Marking note: Award 1 mark for describing the trend (increasing). Award 1 mark for supporting the answer with specific data from the graph.
13. Comparison of rainfall: first half vs. second half of the year: [3]
Sample answer: In the first half of the year (January–June), total rainfall was 80 + 60 + 70 + 90 + 110 + 130 = 540 mm. [1] In the second half (July–December), total rainfall was 150 + 140 + 120 + 100 + 90 + 85 = 685 mm. [1] The second half of the year received more rainfall than the first half, with a difference of 145 mm. The wettest months (June, July, August) fall in the middle to latter part of the year. [1]
Marking note: Award 1 mark for correct total for first half. Award 1 mark for correct total for second half. Award 1 mark for a valid comparison statement. Allow error carried forward if arithmetic is slightly off but the comparison logic is sound.
14. Months suitable for the crop: [4]
Conditions required: rainfall ≥ 100 mm AND temperature ≥ 27°C
Working:
| Month | Rainfall (mm) | ≥100 mm? | Temp (°C) | ≥27°C? | Suitable? |

Marking note: Award 1 mark for correctly checking rainfall condition. Award 1 mark for correctly checking temperature condition. Award 1 mark for identifying at least 4 correct months. Award 1 mark for the complete correct list of 6 months. Deduct 1 mark if the list is incomplete but at least 3 correct months are identified.
15. Limitation of using only Fig. 2 and Fig. 3: [1]
Sample answer: The data only covers one year, so it may not represent the long-term or typical climate pattern of Greenfield Town. Climate is usually based on data collected over at least 30 years. [1]
Alternative acceptable answers:
- The data does not show extreme weather events (e.g., droughts, floods).
- The data does not show wind speed, humidity, or sunshine hours, which are also important climate factors.
- The data is only for one location and may not represent the climate of the wider region.
Marking note: Award 1 mark for any valid limitation. The answer must relate to the data's incompleteness or limited scope.
16. Town with population decrease and percentage decrease: [3]
Town: Town B and Town E both decreased. (Accept either; Town E has the larger decrease.)
Working for Town E:
- Decrease = 54,000 − 48,600 = 5,400
- Percentage decrease = (5,400 ÷ 54,000) × 100 = 10%
Working for Town B:
- Decrease = 32,000 − 30,500 = 1,500
- Percentage decrease = (1,500 ÷ 32,000) × 100 = 4.69% (or 4.7%)
Marking note: Award 1 mark for correctly identifying a town with a decrease. Award 1 mark for correct working. Award 1 mark for correct final answer with unit (%). Accept either Town B or Town E.
17. Reason for unchanged population in Town D: [1]
Sample answer: The number of births and immigration into Town D may have been roughly equal to the number of deaths and emigration, resulting in no net change in population. [1]
Alternative acceptable answers:
- Town D may have reached its carrying capacity or have strict housing limits.
- There may have been no new housing developments or job opportunities to attract new residents.
Marking note: Award 1 mark for any plausible geographical reason.
Section C: Source-Based and Structured Response (15 marks)
18. Three features suggesting a built-up urban area: [3]
Feature 1: High-rise HDB flats / tall buildings [½] Explanation: These indicate high-density residential land use, meaning many people live in a small area, which is typical of urban areas. [½]
Feature 2: Road with vehicles / multi-storey car park [½] Explanation: This shows transport infrastructure is present, indicating the area has a high volume of traffic and movement of people, which is common in urban areas. [½]
Feature 3: Void deck at ground level / paved surfaces [½] Explanation: This indicates commercial or community land use at the ground level, showing the area is designed for human activity and services, typical of urban planning. [½]
Marking note: Award ½ mark per correctly identified feature and ½ mark per valid explanation linking the feature to urban land use. Maximum 3 marks. Accept any three valid features from the photograph with appropriate explanations.
19. Green elements in the urban area: [2]
Evidence from photograph: There are roadside trees (or "parks/green spaces/planted vegetation") visible along the road and between buildings. [1]
Benefit: Trees help to reduce the urban heat island effect by providing shade and releasing moisture through transpiration. Other acceptable benefits: improve air quality, reduce flooding by absorbing rainwater, provide aesthetic value / improve mental well-being of residents, provide habitats for wildlife. [1]
Marking note: Award 1 mark for identifying a green element visible in the photograph. Award 1 mark for a valid benefit.
20. River fieldwork investigation:
(a) Mean width of the river: [2]
Working:
- Mean = (4.2 + 5.8 + 7.1) ÷ 3
- Mean = 17.1 ÷ 3
- Mean = 5.7 m
Marking note: Award 1 mark for correct method (summing and dividing by 3). Award 1 mark for correct final answer with unit.
(b) Trend and reason: [2]
Trend: The river width increases from upstream (4.2 m) to downstream (7.1 m). The river is narrowest at Point X (upstream) and widest at Point Z (downstream). [1]
Reason: As the river flows downstream, it receives water from tributaries (or "more water joins the river from the surrounding drainage basin / through surface runoff"), increasing the volume of water and causing the river to become wider. [1]
Marking note: Award 1 mark for correctly describing the trend (increasing width downstream). Award 1 mark for a valid geographical reason.
(c) Median depth at Point Y: [2]
Working:
- Data: 0.8, 1.2, 1.5, 1.1, 0.6
- Arrange in order: 0.6, 0.8, 1.1, 1.2, 1.5
- Median (middle value) = 1.1 m
Marking note: Award 1 mark for correctly ordering the data. Award 1 mark for identifying the correct median value with unit. Common error: students may forget to order the data before finding the median.
