Subject: Geography (Secondary 4)
Paper: Practice Paper 1 of 5 — Map, Graph & Data Skills
Total Marks: 40

Section A: Data Response [20 marks]

Question 1 [5 marks]

(a) Calculate the population density of Jurong West. Show your working. [2]

Working:
Population density = Population ÷ Land Area
= 263,000 ÷ 14.7
= 17,891 people/km² (accept 17,890–17,900)

[2 marks] — 1 mark for correct formula/method, 1 mark for correct answer with unit.

Common mistake: Forgetting to include "people per km²" as the unit. Award 1 mark if working is correct but unit is missing.

(b) Which district has the highest population density? Show how you determined your answer. [2]

Calculations:

Ang Mo Kio: 167,000 ÷ 13.9 = 12,014 people/km²
Jurong West: 263,000 ÷ 14.7 = 17,891 people/km²
Tampines: 258,000 ÷ 20.9 = 12,344 people/km²
Woodlands: 250,000 ÷ 11.9 = 21,008 people/km²

Answer: Woodlands has the highest population density.

[2 marks] — 1 mark for showing at least two calculations, 1 mark for correct identification of Woodlands.

(c) Suggest one reason why population density varies between districts in Singapore. [1]

Accept any one of the following (or equivalent):

Differences in land area — smaller districts tend to have higher densities if population is similar.
Differences in the number or type of housing units (e.g., more high-rise HDB flats in some districts).
Proximity to the Central Area or employment hubs attracting more residents.
Historical development patterns — newer towns may have lower densities due to more open space planning.

[1 mark] — Award 1 mark for a valid, clearly stated reason.

Question 2 [7 marks]

(a) Describe the temperature pattern shown in Figure 2. [2]

Answer:

Temperatures are high throughout the year, ranging from approximately 25°C to 30°C.
The warmest months are March to April (reaching ~30°C), with slightly cooler temperatures from June to September (27–29°C).
The annual temperature range is small (approximately 3–5°C).

[2 marks] — 1 mark for stating that temperatures are high year-round, 1 mark for describing the small range or identifying the warmest period.

(b) Describe the rainfall pattern shown in Figure 2. [2]

Answer:

Rainfall is highly seasonal. The driest months are January to March (under 30mm per month).
Rainfall increases sharply from May onwards, peaking in September at approximately 250mm.
Rainfall decreases from October to December.
Annual rainfall is high (estimated over 1,400mm).

[2 marks] — 1 mark for identifying the wet and dry seasons, 1 mark for referencing specific data values or the peak month.

(c) Account for the climate characteristics of Bangkok. [3]

Answer:

Bangkok is located at a low latitude (~13°N), close to the equator, so it receives intense solar radiation throughout the year. This explains the consistently high temperatures.
The high rainfall from May to September is caused by the southwest monsoon, which brings warm, moist air from the Indian Ocean, resulting in heavy convectional and orographic rainfall.
The drier period from November to March corresponds to the northeast monsoon, which brings drier continental air from mainland Asia.
The small annual temperature range is typical of tropical locations where day length and solar angle vary little across the year.

[3 marks] — 1 mark for explaining high temperatures (latitude/solar radiation), 1 mark for explaining wet season (monsoon/convectional rainfall), 1 mark for explaining dry season or small temperature range.

Marking note: Award a maximum of 2 marks if the answer lacks reference to specific mechanisms (e.g., just says "monsoon" without explaining moisture source).

Question 3 [7 marks]

(a) Identify the stage of the river shown in each diagram. [2]

Stage X: Youth stage / Upper course
Stage Y: Old stage / Lower course / Mature stage

[2 marks] — 1 mark each. Accept "upper course" for Stage X and "lower course" for Stage Y.

(b) Describe two differences between the river valley at Stage X and Stage Y. [2]

Answer (any two of the following):

The valley at Stage X is narrow and V-shaped, while at Stage Y it is wide with a flat floodplain.
The channel at Stage X is straight, while at Stage Y it meanders.
The valley sides at Stage X are steep, while at Stage Y they are gentle.
Stage Y shows evidence of deposition (floodplain), while Stage X shows a deep, narrow channel suggesting vertical erosion.

[2 marks] — 1 mark per valid difference. Differences must be comparative (i.e., refer to both stages).

(c) Explain how the river valley changes from Stage X to Stage Y. [3]

Answer:

In the upper course (Stage X), the river has high potential energy due to a steep gradient, so vertical (downward) erosion dominates, creating a narrow, V-shaped valley.
As the river moves downstream, the gradient decreases and lateral (sideways) erosion becomes more dominant. The river undercuts valley sides, causing them to retreat and widen the valley.
In the lower course (Stage Y), the river has lower energy and deposits sediment on the inside of bends and during floods, building up a wide floodplain. The river develops meanders as it flows across the flat land.
Over time, weathering and mass movement also contribute to valley widening.

[3 marks] — 1 mark for explaining vertical erosion in Stage X, 1 mark for explaining lateral erosion/valley widening, 1 mark for explaining deposition/floodplain formation in Stage Y.

Question 4 [6 marks]

(a) In which year did Singapore record the highest number of tourist arrivals? [1]

Answer: 2019 (15.1 million)

[1 mark] — Award 1 mark for correct year.

(b) Calculate the percentage decrease in tourist arrivals from 2019 to 2020. Show your working. [3]

Working:
Decrease = 15.1m − 2.7m = 12.4 million
Percentage decrease = (12.4 ÷ 15.1) × 100 = 82.1% (accept 81.5%–82.5%)

[3 marks] — 1 mark for correct subtraction, 1 mark for correct division, 1 mark for correct percentage answer.

Common mistake: Dividing by 2.7 instead of 15.1. Award 2 marks if the method is otherwise correct.

(c) Suggest two reasons for the trend shown from 2020 to 2023. [2]

Answer (any two of the following):

In 2020–2021, the COVID-19 pandemic led to border closures, travel restrictions, and lockdowns, causing a sharp drop in tourist arrivals.
From 2022 onwards, the easing of travel restrictions, reopening of borders, and resumption of international flights led to a recovery in tourist numbers.
Singapore's vaccination-differentiated safe travel lanes and later the full reopening of borders encouraged tourists to return.
Pent-up demand for travel after the pandemic contributed to the rebound in 2022–2023.

[2 marks] — 1 mark per valid reason. Reasons must address the trend (decline then recovery), not just state "pandemic."

Question 5 [5 marks]

(a) Identify two land uses visible in Figure 5. [2]

Accept any two of the following:

Residential (HDB flats)
Transport (road)
Recreational / green space (park)
Water management / drainage (canal)

[2 marks] — 1 mark per valid land use identified from the photograph.

(b) Describe one piece of evidence from the photograph that suggests this area is densely populated. [1]

Accept any one of the following:

The presence of high-rise HDB flats, which house many people in a small land area.
The large number of residential blocks visible in a small area.
The road is lined with buildings, indicating intensive land use.

[1 mark] — Award 1 mark for a valid observation linked to population density.

(c) Suggest one challenge that residents in this area might face, and explain your answer. [2]

Accept any one of the following with explanation:

Traffic congestion: The road with many vehicles suggests high traffic volume, which can lead to congestion during peak hours, increasing commute times.
Limited green space: Although there is a small park, the dominance of built-up areas means residents may have limited access to nature and recreational areas, affecting quality of life.
Noise pollution: Living near a busy road and in close proximity to many residents can result from constant traffic and human activity.
Urban heat island effect: The concentration of concrete buildings and roads absorbs and re-radiates heat, making the area warmer than surrounding rural areas.

[2 marks] — 1 mark for identifying a valid challenge, 1 mark for a clear explanation linking the challenge to the urban context.

Section B: Structured Response [20 marks]

Question 6 [7 marks]

(a) Compare the temperature patterns of City A and City B. In your answer, refer to specific data from Figure 6. [4]

Answer:

City A has consistently high temperatures year-round, ranging from 26°C to 28°C, with very little variation (annual range of ~2°C).
City B has a much wider temperature range, from approximately 2°C in January to 22°C in July, giving an annual range of ~20°C.
City A's temperatures peak around April (28°C) and dip slightly in December–January (26°C), while City B's temperatures follow a clear seasonal cycle with warmest temperatures in July–August and coldest in January–February.
City A is warmer than City B in every month of the year; the difference is greatest in City B's winter months (January: 2°C vs 26°C = 24°C difference).

[4 marks] — 1 mark for describing City A's pattern with data, 1 mark for describing City B's pattern with data, 1 mark for a direct comparison (e.g., range or specific months), 1 mark for referencing specific numerical values from the graph.

Marking note: Award a maximum of 2 marks if no data values are quoted.

(b) Explain why City A experiences a smaller annual temperature range than City B. [3]

Answer:

City A is located at 5°N, very close to the equator. At low latitudes, the angle of the sun is high and day length remains relatively constant throughout the year, so solar energy input is consistent, resulting in stable temperatures.
City B is located at 45°N, a mid-latitude location. At this latitude, there is significant variation in solar angle and day length between summer and winter. In summer, longer days and a higher solar angle lead to warmer temperatures; in winter, shorter days and a lower solar angle result in much cooler temperatures.
The greater seasonal variation in solar radiation at higher latitudes directly causes a larger annual temperature range.

[3 marks] — 1 mark for explaining City A's low latitude/consistent solar input, 1 mark for explaining City B's mid-latitude/seasonal variation, 1 mark for linking solar angle/day length to temperature differences.

Question 7 [7 marks]

(a) State the largest source of Singapore's water supply. [1]

Answer: NEWater (40%)

[1 mark] — Award 1 mark for correct answer.

(b) Calculate the combined percentage of water from NEWater and Desalination. Show your working. [2]

Working:
NEWater = 40%
Desalination = 10%
Combined = 40% + 10% = 50%

[2 marks] — 1 mark for correct values identified, 1 mark for correct sum.

(c) Explain why Singapore has invested in NEWater and desalination technologies. [4]

Answer:

Singapore has limited land area and natural water resources, making it difficult to rely solely on local catchment and imported water. Diversifying water sources enhances water security.
Imported water from Malaysia is subject to political agreements and potential supply disruptions. Reducing dependence on imports through NEWater and desalination ensures a more reliable and self-sufficient water supply.
NEWater uses advanced membrane technology to treat used water into ultra-clean, high-grade reclaimed water. This is a sustainable solution as it recycles water within the system, reducing waste.
Desalination converts seawater into fresh water, providing a weather-independent source that is not affected by droughts or reduced rainfall due to climate change.
Both technologies support Singapore's goal of water self-sufficiency, especially as population and economic growth increase water demand. They are part of Singapore's "Four National Taps" strategy.

[4 marks] — 1 mark for limited natural resources/land constraints, 1 mark for reducing import dependence, 1 mark for explaining NEWater (recycling/reclaimed water), 1 mark for explaining desalination (seawater/weather-independent) or linking to water security strategy.

Marking note: Award a maximum of 3 marks if the answer does not mention both NEWater and desalination specifically.

Question 8 [8 marks]

(a) Describe the relationship shown in Figure 8. [2]

Answer:

There is a general positive correlation between GDP per capita and CO₂ emissions per capita.
As GDP per capita increases, CO₂ emissions per capita tend to increase as well.
Countries with low GDP per capita generally have low emissions, while countries with high GDP per capita generally have higher emissions.

[2 marks] — 1 mark for identifying a positive relationship/correlation, 1 mark for describing the trend (as one increases, so does the other).

(b) Identify one anomaly from the scatter graph and suggest a reason for it. [2]

Answer (example):

Anomaly: A country with relatively high GDP per capita but lower-than-expected CO₂ emissions (e.g., a country that falls below the general trend line).
Reason: This country may have invested heavily in renewable energy sources (e.g., hydroelectric, solar, or wind power), reducing its reliance on fossil fuels despite high economic output. Alternatively, the country may have a service-based economy rather than a manufacturing-based one, resulting in lower industrial emissions.

[2 marks] — 1 mark for identifying a valid anomaly (a data point that does not follow the general trend), 1 mark for a plausible explanation.

(c) Discuss whether reducing carbon dioxide emissions should be the responsibility of all countries. [4]

Answer (balanced discussion expected):

Yes, it should be the responsibility of all countries:

Climate change is a global problem; greenhouse gases mix in the atmosphere regardless of where they are emitted. Every country's emissions contribute to global warming, so all nations have a shared responsibility to reduce them.
Figure 8 shows that high-GDP countries tend to have the highest per capita emissions, suggesting that developed nations have a greater historical responsibility and should lead in emission reductions.
Even low-emitting countries can contribute by adopting cleaner technologies and sustainable practices as they develop, avoiding the high-emission development path taken by industrialised nations.

However, there are arguments for differentiated responsibility:

Figure 8 shows that many low-GDP countries have very low per capita emissions. Expecting these countries to reduce emissions may hinder their economic development and poverty alleviation efforts.
Developed countries have historically contributed the most to cumulative emissions and have greater financial and technological capacity to reduce emissions. They should therefore bear a larger share of the burden.
Some countries depend heavily on fossil fuels for energy and economic growth, and transitioning to cleaner alternatives requires significant investment that may not be immediately feasible.

Conclusion: All countries should take responsibility, but the extent and pace of action should be differentiated based on economic capacity, historical emissions, and development needs. International cooperation and support (e.g., climate finance, technology transfer) are essential.

[4 marks] — 1 mark for arguing that all countries should take responsibility (with reasoning), 1 mark for arguing that responsibility should be differentiated (with reasoning), 1 mark for referring to evidence from Figure 8, 1 mark for a clear, balanced conclusion or synthesis.

Marking note: Award a maximum of 2 marks if the answer is one-sided (only argues one position). Award a maximum of 3 marks if no reference is made to Figure 8.
