Geography Secondary 1 | Map, Graph & Data Skills | Version 2 of 5

Section A: Map Skills (15 marks)

1. (a) [1 mark]

• Answer: 1 cm on the map represents 25,000 cm (or 250 m or 0.25 km) on the ground.
• Marking note: Award 1 mark for a correct statement linking map distance to real-world distance. Accept equivalent answers such as "1 cm = 250 m" or "1 cm represents 0.25 km."

1. (b) [2 marks]

• Working:
  • Map distance = 6.8 cm
  • Scale: 1 cm = 25,000 cm
  • Actual distance = 6.8 × 25,000 = 170,000 cm
  • Convert to km: 170,000 ÷ 100,000 = 1.7 km
• Answer: 1.7 km
• Marking note: Award 1 mark for correct multiplication (6.8 × 25,000 = 170,000 cm). Award 1 mark for correct conversion to km (1.7 km). If the final answer is correct but no working shown, award 1 mark only.

2. (a) [1 mark]

• Answer: 4071 (Accept the correct 4-figure grid reference based on the described map context — the health clinic is in grid square 4071, read as easting 40, northing 71.)
• Marking note: Accept any plausible 4-figure grid reference consistent with a southwestern location. Award 1 mark for a correct 4-figure reference.

2. (b) [2 marks]

• Answer: 415738 (Accept a plausible 6-figure grid reference for a bridge crossing Sungei Melati in grid square 4173.)
• Marking note: Award 1 mark for correctly identifying the easting subdivision (e.g., 415) and 1 mark for the northing subdivision (e.g., 738). Common error: reversing easting and northing order.

3. (a) [1 mark]

• Answer: South-east
• Marking note: Accept "SE" or "south-east." Award 1 mark for the correct compass direction.

3. (b) [1 mark]

• Answer: 4171 (Accept a plausible 4-figure grid reference for a viewpoint on a hill in a south-easterly direction from grid square 4072.)

4. (a) [1 mark]

• Answer: The land is a hill / The land rises to a peak in the centre / Contour lines form closed circles indicating a hill.

4. (b) [2 marks]

• Answer: The maximum possible height is between 80 m and 90 m. Since the highest visible contour line is 80 m and the contour interval is 10 m, the actual summit must be above 80 m but below the next contour line at 90 m.
• Marking note: Award 1 mark for stating the range (80–90 m or "above 80 m but less than 90 m"). Award 1 mark for explaining the reasoning using the contour interval. Common error: stating exactly 80 m without acknowledging it could be higher.

14. (a) [1 mark]

• Answer: There is a negative correlation / as the distance from the city centre increases, the average house price decreases.
• Marking note: Award 1 mark for describing the inverse/negative relationship.

14. (b) [2 marks]

• Answer: The estimated house price at 6 km is approximately **$0.9 million** (or$900,000). This is obtained by interpolation between the values at 5 km ($1.0 million) and 7 km ($0.8 million). At 6 km, which is halfway between 5 km and 7 km, the price would be approximately halfway between $1.0 million and$0.8 million.
• Marking note: Award 1 mark for a reasonable estimate between $0.8 million and$1.0 million. Award 1 mark for explaining the interpolation method.

14. (c) [1 mark]

• Answer: Any one of the following:
  • Houses near the city centre are closer to jobs, amenities, and services, making them more desirable.
  • Land is scarcer near the city centre, driving up prices.
  • Better transport links near the city centre increase accessibility and demand.
• Marking note: Award 1 mark for a valid reason.

Section C: Data Response & Application (10 marks)

15. [1 mark]

• Answer: The location / testing point along the river (Point P, Q, or R) is the independent variable.
• Marking note: Award 1 mark for correctly identifying the independent variable as the location/testing point. Accept "the point along the river" or "where the sample was taken."

16. [1 mark]

• Answer: The dissolved oxygen levels decrease from Point P (9.2 mg/L) to Point Q (6.5 mg/L) to Point R (3.8 mg/L). / Dissolved oxygen decreases as you move downstream.
• Marking note: Award 1 mark for describing the decreasing trend. Accept answers that reference the data values.

17. [3 marks]

• Answer: Point P has the best water quality.
• Evidence 1: It has the highest dissolved oxygen level (9.2 mg/L), which indicates cleaner, healthier water that can support more aquatic life.
• Evidence 2: It has no pollutants detected, unlike Points Q and R which have detergents, organic waste, heavy metals, and chemical waste.
• Marking note: Award 1 mark for correctly identifying Point P. Award 1 mark for each valid piece of evidence (up to 2 marks). Accept reference to pH being closest to neutral (6.8) as additional evidence.

18. [2 marks]

• Answer: One possible source of pollution at Point Q is domestic sewage / household wastewater from the nearby housing estate. This introduces organic waste and detergents into the river, which reduces dissolved oxygen levels as bacteria decompose the organic matter, making the water less suitable for aquatic life.
• Marking note: Award 1 mark for identifying a valid source (e.g., domestic sewage, household waste, detergents from washing). Award 1 mark for explaining how it affects water quality (e.g., reduces dissolved oxygen, adds pollutants).

19. [1 mark]

• Answer: A pH of 4.5 means the water is acidic. This indicates that the water has been contaminated by chemical pollutants / industrial waste, which makes it harmful to most aquatic organisms.
• Marking note: Award 1 mark for stating that the water is acidic and linking it to pollution. Accept "the water is acidic / polluted / harmful to living things."

20. [2 marks]

• Answer: One way to improve water quality at Point R is to treat industrial wastewater before it is discharged into the river. Factories should be required to install water treatment systems that remove heavy metals and harmful chemicals. This would reduce the pollutants entering the river, allowing dissolved oxygen levels to recover and aquatic life to return.
• Marking note: Award 1 mark for suggesting a valid method (e.g., treating industrial waste, enforcing environmental regulations, building water treatment plants). Award 1 mark for explaining how the method would improve water quality.
