Answers

SA2 Practice Paper — Geography Secondary 1

Answer Key (Version 5 of 5)

Section A: Map Skills

1. [1 mark]

Accept any valid four-figure grid reference read correctly from the map insert (easting first, then northing).
Example answer: 3264
Marking note: Award 1 mark for a correct four-figure grid reference. Deduct if order is reversed (northing before easting).

2. [1 mark]

Accept any valid six-figure grid reference (easting to nearest tenth, then northing to nearest tenth).
Example answer: 335618
Marking note: Award 1 mark for a correct six-figure grid reference. Accept minor variations depending on map insert.

3. [1 mark]

Accept the correct eight-point compass direction.
Example answer: South-west
Marking note: Award 1 mark for the correct direction. Accept abbreviated forms (e.g., SW).

4. [2 marks]

Step 1: Measure the straight-line distance on the map in centimetres. (Example: 4.5 cm)
Step 2: Use the map scale to convert cm to km. (Example: 1 cm = 0.5 km, so 4.5 cm × 0.5 = 2.25 km)
Answer: 2.25 km (accept values consistent with the map insert)
Marking: Award 1 mark for correct measurement/conversion working, 1 mark for correct final answer with unit.

5. [2 marks]

Expected answer (example): The land is low-lying, with heights between 0 m and 10 m above sea level. The contour lines are widely spaced, indicating gentle slopes. There is a small hill in the north-eastern corner of the grid square reaching about 15 m.
Marking: Award 1 mark for describing height/altitude, 1 mark for describing shape/relief (e.g., flat, gentle slope, steep, undulating). Accept answers consistent with the map insert.

6. [2 marks]

Settlement pattern: Linear / Nucleated / Dispersed (accept the correct pattern based on the map insert).
Example answer: Linear — the buildings are arranged along a road.
Marking: Award 1 mark for correct identification of settlement pattern, 1 mark for valid map evidence.

7. [3 marks]

Example answer: I disagree.
- Reason 1: The area is low-lying and near a river, so it is prone to flooding.
- Reason 2: The contour lines are close together in parts, indicating steep slopes that would make construction difficult and costly.
Marking: Award 1 mark for stating agree/disagree, 2 marks for two valid geographical reasons (1 mark each). Accept answers consistent with the map insert.

8. [3 marks]

Example answer:
- Advantage 1: It would provide faster and more convenient access for residents to the jetty for transport and trade.
- Advantage 2: It could improve economic opportunities by connecting the settlement to the coast for fishing and tourism.
- Disadvantage: Building the road through the area may require clearing vegetation or forest, which could harm the natural environment.
Marking: Award 1 mark each for two valid advantages and 1 mark for one valid disadvantage. Answers must be geographical in nature.

Section B: Graph and Data Interpretation

9. [1 mark]

Answer: November
Marking note: Award 1 mark for the correct month only.

10. [2 marks]

Working: 180 + 140 + 160 + 210 + 250 + 220 + 190 + 200 + 230 + 270 + 310 + 260 = 2620 mm
Answer: 2620 mm
Marking: Award 1 mark for correct addition/working, 1 mark for correct final answer with unit.

11. [2 marks]

Working: Total annual rainfall ÷ 12 = 2620 ÷ 12 = 218.33 mm
Answer: 218.3 mm (accept 218 mm or 218.33 mm)
Marking: Award 1 mark for correct division/working, 1 mark for correct answer with unit.

12. [3 marks]

Expected answer: Rainfall generally increases from January (180 mm) to November (310 mm), with some fluctuations. For example, rainfall dips slightly in February (140 mm) and July (190 mm) but the overall trend is an increase. The highest rainfall occurs in November (310 mm) and the lowest in February (140 mm). From June to November, rainfall is consistently above 200 mm.
Marking: Award 1 mark for identifying the overall trend (increase), 1 mark for using at least two specific data values to support the trend, 1 mark for noting fluctuations or describing the pattern in detail.

13. [1 mark]

Example answer: November and December fall during the Northeast Monsoon season, which brings heavy rainfall to the region.
Marking note: Award 1 mark for a valid reason related to monsoon season, convectional rain, or tropical climate.

14. [1 mark]

Answer: Town C, 38 thousand
Marking note: Award 1 mark for correctly identifying the town AND stating the population.

15. [2 marks]

Working: Most populated = Town E (71 thousand); Least populated = Town C (38 thousand). Difference = 71 − 38 = 33 thousand.
Answer: 33 thousand
Marking: Award 1 mark for correct identification of both towns, 1 mark for correct answer with unit.

16. [2 marks]

Expected answer: The statement is incorrect. Town E has a population of 71 thousand and Town C has 38 thousand. Twice the population of Town C would be 76 thousand (38 × 2 = 76). Since 71 ≠ 76, Town E does not have twice the population of Town C. It is close but not exactly double.
Marking: Award 1 mark for stating the statement is incorrect, 1 mark for using data to show the calculation/comparison.

17. [2 marks]

Working: Highest temperature = 31 °C (July); Lowest temperature = 27 °C (March). Range = 31 − 27 = 4 °C.
Answer: 4 °C
Marking: Award 1 mark for correct identification of highest and lowest values, 1 mark for correct range with unit.

18. [1 mark]

Example answer: A line graph only shows trends between data points and does not show the exact value for every day or week — it assumes a smooth change between points, which may not reflect actual daily variations.
Marking note: Award 1 mark for a valid limitation (e.g., assumes continuous data, does not show individual data points clearly, may oversimplify fluctuations).

Section C: Data Response and Application

19. (a) [3 marks]

Worst water quality: Sampling Point B
Evidence 1: It has the lowest dissolved oxygen level (4.1 mg/L), which indicates high pollution.
Evidence 2: It has the highest turbidity (42 NTU), meaning the water is very murky/cloudy, and the lowest pH (5.2), indicating acidic conditions.
Marking: Award 1 mark for correct identification of Point B, 2 marks for two valid pieces of evidence from the table (1 mark each).

(b) [1 mark]

Example answer: Discharge of chemical waste / effluent from the factory.
Marking note: Award 1 mark for a valid pollution source related to the factory.

Expected answer: From Point B to Point D, the water quality improves. Dissolved oxygen increases from 4.1 mg/L at Point B to 7.5 mg/L at Point D, indicating less pollution. The pH rises from 5.2 (acidic) to 6.8 (closer to neutral), showing the water is becoming less acidic. Turbidity decreases from 42 NTU to 12 NTU, meaning the water is becoming clearer as pollutants settle out or are diluted further downstream.
Marking: Award 1 mark for stating that water quality improves, 1 mark for describing the change in at least one variable with data, 1 mark for describing the change in a second variable with data.

20. (a) [3 marks]

Expected answer: As the distance from the car park increases, the number of litter items decreases. At 0 m from the car park, there are 48 litter items, but at 100 m, there are only 8 litter items. This shows a negative relationship — the further away from the car park, the less litter is found. For example, at 40 m there are 22 items, and at 80 m there are only 10 items.
Marking: Award 1 mark for identifying the relationship (negative/inverse), 1 mark for describing the trend, 1 mark for using at least two data values to support the answer.

(b) [1 mark]

Example answer: The car park is where people gather and consume food/drinks, so most litter is dropped near the car park. Fewer people walk further away, so less litter is found at greater distances.
Marking note: Award 1 mark for a valid reason related to human activity/concentration near the car park.

Type of graph: Line graph
Reason: A line graph is more appropriate because the data shows a continuous trend (distance is a continuous variable) and it clearly shows how the number of litter items changes as distance increases. A bar graph would treat each distance as a separate category rather than showing the continuous relationship.
Marking: Award 1 mark for correct graph type, 1 mark for a valid reason.
