Answers
Secondary 1 Geography Quiz – Map Graph Data Skills
Answer Key
Section A: Map Skills (Questions 1–10)
1. State the four-figure grid reference of the school.
Answer: 3346
[1]
Note: Read easting (33) first, then northing (46). The school lies in grid square 3346.
2. State the six-figure grid reference of the jetty.
Answer: 343421
[1]
Note: The jetty is in grid square 3442. Estimating the position within the square: 3/10 across (→ 343) and 1/10 up (→ 421). Accept 343421 or any reasonable estimate such as 344421 if the jetty is near the centre of the square. Award 1 mark for correct method and reasonable estimate.
3. What is the approximate height of Bukit Tanah Tinggi? Give your answer in metres.
Answer: 85 m
[1]
Note: The spot height of 85 m is marked in grid square 3245 where Bukit Tanah Tinggi is located.
4. In which direction is the mosque from the school?
Answer: South-west
[1]
Note: The mosque is in grid square 3144, while the school is in 3346. From the school, the mosque is to the left (west) and down (south), i.e., south-west.
5. Describe the direction of flow of Sungai Laju.
Answer: From north-east to south-west
[1]
Note: The river flows from grid square 3147 (north-east) to 3443 (south-west). Accept "north to south" or "north-east to south-west".
6. What is the straight-line distance between the school and the mosque? Use the scale 1:50,000. Show your working.
Answer:
- Measure the distance on the map (e.g., approximately 4.4 cm).
- 4.4 cm × 50,000 = 220,000 cm = 2.2 km
Accept any reasonable measurement between 2.0 km and 2.5 cm on map → 2.0–2.5 km.
[2]
Marking: 1 mark for correct method (multiplying by scale), 1 mark for correct answer with unit.
7. State two pieces of evidence from the map that suggest the area around grid square 3246 is suitable for farming.
(a) The area is relatively flat (contours are widely spaced).
(b) There is a water source nearby (Sungai Laju flows close by).
[2]
Accept any two of: flat land, proximity to river/water source, presence of woodland (fertile soil), accessible by road. 1 mark each.
8. A student says: "The land in grid square 3345 is flat." Do you agree? Use evidence from the map to explain your answer.
Answer:
Yes, I agree. The contour lines in grid square 3345 are widely spaced, which indicates gentle slopes or flat land. Additionally, a main road runs through this grid square, which is usually built on relatively flat terrain.
[2]
Marking: 1 mark for stating agreement/disagreement with reason, 1 for using map evidence (contour spacing or road).
9.
(a) Which town has the highest population?
Answer: Pekan Baru
[1]
(b) What is the total population of all four towns? Show your working.
Answer: 12,500 + 8,200 + 15,300 + 6,700 = 42,700
[1]
10.
(a) What is the highest monthly rainfall recorded?
Answer: 280 mm (in December)
[1]
(b) In which month is the lowest temperature recorded?
Answer: January
[1]
(c) Describe the relationship between rainfall and temperature in Town X.
Answer: When the temperature is lower (e.g., January at 25°C), the rainfall is higher (280 mm in December/January). When the temperature is higher (e.g., May at 30°C), the rainfall is lower (60 mm in June). This shows an inverse/negative relationship — as temperature increases, rainfall decreases.
[2]
Marking: 1 mark for identifying the pattern, 1 mark for describing the relationship (inverse/negative).
Section B: Graph and Data Interpretation (Questions 11–16)

(b) Estimate the amount of CO₂ absorbed when 500 trees are planted.
Answer: Approximately 150 tonnes (accept a reasonable estimate based on the trend line, e.g., 140–160 tonnes).
[1]
16.
(a) Which school generated more paper waste?
Answer: Eco School
[1]
(b) What was the total waste generated by Green School? Show your working.
Answer: 40 + 25 + 35 + 10 = 110 tonnes
[1]
(c) Suggest one reason why Eco School may have generated less plastic waste than Green School.

[2]
Marking: 1 mark for a valid suggestion, 1 mark for a brief explanation. Accept any reasonable answer.
Section C: Data Response (Questions 17–20)
17.
(a) In which year was the highest number of flood incidents recorded?
Answer: 2022
[1]
(b) Describe the relationship between rainfall and the number of flood incidents.
Answer: There is a positive relationship between rainfall and flood incidents. As the amount of rainfall increases, the number of flood incidents also increases. For example, in 2022, rainfall was the highest at 3,000 mm and flood incidents were also the highest at 9.
[2]
Marking: 1 mark for identifying the relationship (positive), 1 mark for supporting with data from the table.
(c) Suggay one way Town Y can reduce the number of flood incidents.
Answer: Town Y can build more drains or improve the drainage system to allow rainwater to flow away more quickly, reducing the risk of flooding.
[2]
Marking: 1 mark for a valid suggestion, 1 mark for a brief explanation. Accept any reasonable answer (e.g., building retention ponds, planting more trees, constructing flood barriers).
18.
(a) Calculate the total decrease in forest cover from 2000 to 2020. Show your working.
Answer: 150,000 − 100,000 = 50,000 km²
[1]
(b) Calculate the average rate of decrease in forest cover per year over this period. Show your working.
Answer: 50,000 ÷ 20 = 2,500 km² per year
[2]
Marking: 1 mark for correct method (total decrease ÷ number of years), 1 mark for correct answer with unit.
(c) Suggest two reasons why the forest cover in Country Z has decreased.
(a) Deforestation for agriculture (clearing land for farming).
(b) Urbanisation (clearing forests to build houses, roads, and infrastructure).
[2]
Accept any two valid reasons: logging, mining, forest fires, population growth, industrial development. 1 mark each.
19.
(a) Which river has the best water quality?
Answer: River Alpha
[1]
(b) A student claims: "River Gamma is polluted because of domestic sewage only." Using the data and your knowledge, explain why this statement may not be fully correct.
Answer:
The statement may not be fully correct because water pollution can come from multiple sources, not just domestic sewage. River Gamma's poor water quality (WQI of 40) could also be caused by industrial waste, agricultural runoff containing fertilisers and pesticides, or construction site runoff. The data only shows the overall water quality rating, not the specific sources of pollution. Therefore, it is not accurate to conclude that domestic sewage is the only cause.
[3]
Marking: 1 mark for stating that pollution has multiple sources, 1 mark for giving at least one other possible source, 1 mark for explaining that the data does not specify the source.
20.
(a) Which city has the highest PM2.5 level?
Answer: City S
[1]
(b) Describe the relationship between the number of vehicles and the PM2.5 level.
Answer: There is a positive relationship between the number of vehicles and the PM2.5 level. As the number of vehicles increases, the PM2.5 level also increases. For example, City S has the most vehicles (3.5 million) and the highest PM2.5 level (55 µg/m³), while City R has the fewest vehicles (0.9 million) and the lowest PM2.5 level (20 µg/m³).
[2]
Marking: 1 mark for identifying the relationship (positive), 1 mark for supporting with data.
(c) City R wants to keep its PM2.5 level low even as the number of vehicles increases. Suggest two strategies the city can adopt.
(a) Encourage the use of public transport (e.g., buses and MRT) to reduce the number of private vehicles on the road.
(b) Promote the use of electric vehicles, which produce fewer emissions than petrol or diesel vehicles.
[2]
Accept any two valid strategies: carpooling, congestion charges, stricter emission standards, cycling infrastructure, planting more trees. 1 mark each.
