Answer Key – Map Graph Data Skills

Section A: Map Reading and Interpretation

1.(a) [2]

Working:

Map distance = 8.4 cm
Scale = 1:50,000 → 1 cm on map = 50,000 cm on ground
Actual distance = 8.4 × 50,000 = 420,000 cm
420,000 cm ÷ 100,000 = 4.2 km

Answer: 4.2 km

Marking notes: 1 mark for correct method, 1 mark for correct answer with unit. Award 1 mark if method is correct but arithmetic error is made.

1.(b) [1]

Answer: A scale of 1:50,000 shows more detail (or a larger-scale view) of a small area compared to 1:250,000, which covers a larger area with less detail.

Marking notes: Accept any valid advantage related to greater detail, larger representation of features, or ability to show individual buildings/landmarks.

2.(a) [2]

Working:

From 4125 to 4529: easting changes from 41 to 45 (difference of 4, i.e., 4000 m), northing changes from 25 to 29 (difference of 4, i.e., 4000 m).
Three-tenths along: easting = 41 + (0.3 × 4) = 41 + 1.2 = 41.2 → easting 412
Northing = 25 + (0.3 × 4) = 25 + 1.2 = 25.2 → northing 252
Six-figure grid reference: 412252

Answer: 412252

Marking notes: 1 mark for correct method of interpolation, 1 mark for correct six-figure grid reference. Accept 412252 only.

2.(b) [1]

Answer: The river flows from the southwest to the northeast (or from a lower easting/northing to a higher easting/northing).

Marking notes: Accept "southwest to northeast" or "SW to NE". Do not accept vague answers like "upwards" or "north".

3.(a) [1]

Working:

Base = 55 m, contour interval = 10 m
1st contour line = 65 m; 2nd = 75 m; 3rd = 85 m

Answer: 85 m

3.(b) [1]

Working:

Relief = 85 m − 35 m = 50 m

Answer: 50 m

3.(c) [1]

Answer: The hill is a conical hill (or a hill with even, uniform slopes on all sides).

Marking notes: Accept "conical", "even slopes", or "symmetrical". Do not accept "volcanic cone" unless specified.

4.(a) [2]

Answer (any two of the following):

The settlement is located on flat land (low relief / low contour values), which is suitable for farming.
It is near a river, which provides water for irrigation.
The surrounding area shows agricultural land use (e.g., fields, plantations).
The area has fertile alluvial soil deposited by the river.

Marking notes: 1 mark per valid piece of evidence, maximum 2 marks. Evidence must be map-based.

4.(b) [1]

Answer: The settlement is at risk of flooding from the nearby river during heavy rainfall.

Marking notes: Accept flooding, waterlogging, or soil erosion. Do not accept "earthquakes" or other unrelated hazards.

5.(a) [2]

Working:

Map distance = 7.2 cm
Scale = 1:50,000
Actual distance = 7.2 × 50,000 = 360,000 cm
360,000 ÷ 100,000 = 3.6 km

Answer: 3.6 km

Marking notes: 1 mark for correct method, 1 mark for correct answer with unit.

5.(b) [1]

Answer: A single solid line (or a thin black line) on a topographic map.

Marking notes: Accept "single line", "solid line", or description of the standard OS/map symbol for a single carriageway road.

6.(a) [1]

Answer: Agriculture (or farmland / cultivated land / smallholder farming).

Marking notes: Accept "agriculture", "farming", "crop cultivation", or "smallholdings".

6.(b) [1]

Answer: Southeast Asia has a warm, wet climate (or high rainfall and temperatures) that is suitable for growing crops such as rice throughout the year.

Marking notes: Accept any valid reason related to climate, population demand, or traditional farming practices.

7. [3]

Answer (model response):

I agree that the area around grid reference 4128 is suitable for building a reservoir. The map shows a narrow valley (or gorge) at this location, which would be an ideal site for damming. The contour lines are close together, indicating steep valley sides that would help contain the water. Additionally, there is a river flowing through this area, providing a reliable water source to fill the reservoir. The higher elevation of the surrounding land would also allow water to be distributed by gravity.

Marking notes: Award 1 mark for stating agreement or disagreement with valid reasoning, 1 mark for identifying a relevant map feature (narrow valley, steep sides, river), and 1 mark for explaining how the feature supports the claim. Maximum 3 marks.

8.(a) [1]

Answer: X is a ridge (or spur / hilltop).

Marking notes: Accept "ridge", "spur", or "hilltop" depending on the cross-section shown. The most likely answer is a ridge or elevated landform.

8.(b) [2]

Working:

Vertical exaggeration = Vertical scale denominator ÷ Horizontal scale denominator
VE = 50,000 ÷ 5,000 = 10 times

Answer: 10 times (10×)

Marking notes: 1 mark for correct formula, 1 mark for correct answer. Accept "10" or "10×".

9.(a) [1]

Answer: A mangrove is a coastal woodland (or tropical coastal forest) that grows in saline or brackish water in intertidal zones.

Marking notes: Must mention coastal/tidal environment and salt-tolerant trees. Do not accept "swamp" alone.

9.(b) [2]

Answer:

Mangrove roots trap sediments and stabilise the coastline, reducing erosion.
Mangroves act as a natural buffer against storm surges, waves, and tsunamis, protecting the coast and human settlements behind them.

Marking notes: 1 mark per valid point. Accept any two valid explanations related to coastal protection.

10. [4]

Answer (model response):

Two factors that make grid reference 4523 suitable for tourism development are:

Coastal location: The site is near the coast, which provides scenic views, beaches, and opportunities for water-based recreational activities such as swimming, snorkelling, and boating. Coastal areas are attractive to tourists seeking leisure and relaxation.
Accessibility: The map shows that the site is near a road, making it easily accessible by car or bus. Good transport links are important for attracting tourists and supporting the development of resort facilities.

Marking notes: Award 1 mark per identified factor and 1 mark per explanation (2 + 2 = 4 marks). Accept other valid factors such as flat land for construction, proximity to natural attractions, or availability of water supply.

Section B: Graph and Data Interpretation

11. [2]

Highest: 27.3 °C (in May)

Lowest: 26.5 °C (in January and December)

Marking notes: 1 mark for each correct answer with unit. Both must be correct for full marks.

12. [2]

Working:

Annual temperature range = Highest temperature − Lowest temperature
Range = 27.3 − 26.5 = 0.8 °C

Answer: 0.8 °C

Marking notes: 1 mark for correct method, 1 mark for correct answer with unit.

13. [3]

Answer (model response):

Kota Pinang receives high rainfall throughout the year, with monthly rainfall ranging from 150 mm to 380 mm. The driest months are July (150 mm) and August (160 mm), while the wettest months are November (380 mm) and December (350 mm). Rainfall is generally lower from June to August and higher from October to December. There is no distinct dry season, as all months receive more than 60 mm of rain.

Marking notes: Award 1 mark for describing the overall pattern (high rainfall year-round), 1 mark for referencing specific months and figures, and 1 mark for noting the seasonal variation or absence of a dry season. Maximum 3 marks.

14. [4]

Characteristic 1: High temperatures throughout the year — The average monthly temperatures range from 26.5 °C to 27.3 °C, showing very little variation. This is typical of equatorial climates, which experience consistently high temperatures due to the high angle of the sun throughout the year.

Characteristic 2: High rainfall throughout the year — Monthly rainfall ranges from 150 mm to 380 mm, with all months receiving significant rainfall. Equatorial climates are characterised by high annual rainfall with no true dry season, as convectional rain occurs regularly due to intense heating.

Marking notes: Award 1 mark per correctly identified characteristic and 1 mark per explanation linked to the data (2 + 2 = 4 marks). Accept other valid equatorial climate characteristics supported by the data.

15.(a) [1]

Answer: A line graph.

15.(b) [1]

Answer: A bar graph.

15.(c) [2]

Answer: Temperature is a continuous variable that changes gradually over time, so it is best represented by a line graph, which shows trends and patterns clearly. Rainfall is measured as a discrete total for each month, so it is best shown using a bar graph, which allows easy comparison of monthly totals. Using different graph types makes the climate graph easier to read and interpret.

Marking notes: Award 1 mark for explaining why a line graph is used for temperature and 1 mark for explaining why a bar graph is used for rainfall. Accept alternative valid explanations.

16. [2]

Answer: Indonesia had the highest number of tourist arrivals with 2.8 million visitors.

Marking notes: 1 mark for correct country, 1 mark for correct figure with unit.

17. [2]

Working:

Total = 1.2 + 2.8 + 0.9 + 1.5 + 0.7 = 7.1 million

Answer: 7.1 million

Marking notes: 1 mark for correct method (adding all values), 1 mark for correct answer with unit.

18. [3]

Countries: Australia (0.7 million) and India (0.9 million)

Reason: Arrivals from these countries might be lower because they are farther away from Singapore, resulting in higher travel costs and longer flight times. Additionally, there may be fewer direct flight connections or less established travel routes compared to neighbouring countries like Indonesia and Malaysia.

Marking notes: Award 1 mark for correctly identifying both countries (1 mark total, not 0.5 each — both must be correct), and 1 mark for a valid reason. Award an additional 1 mark for elaboration or a second valid reason. Maximum 3 marks.

19. [4]

Answer (model response):

Country X has a population structure with a broad base, indicating a high proportion of young people (18% aged 0–14). The working-age population (15–64) is the largest group at 70%, suggesting a large labour force. The elderly population (65+) makes up 12%, indicating a growing ageing population. In the younger age groups, there are slightly more males than females, which is typical of most populations. However, in the 65+ age group, there are significantly more females than males, reflecting the longer life expectancy of women. Overall, Country X appears to be a developing or newly developed country with a youthful population that is beginning to age.

Marking notes: Award 1 mark for describing the youth population, 1 mark for describing the working-age population, 1 mark for describing the elderly population, and 1 mark for commenting on gender distribution. Maximum 4 marks. Accept other valid observations supported by the data.

20.(a) [1]

Answer: The dependency ratio is the ratio of the non-working population (those aged 0–14 and 65+) to the working-age population (those aged 15–64), usually expressed as a percentage or ratio.

Marking notes: Must mention dependents (young and elderly) and working-age population. Do not accept vague definitions.

20.(b) [3]

Working:

Dependents = Population aged 0–14 + Population aged 65+ = 18% + 12% = 30%
Working-age population = 70%
Dependency ratio = (30 ÷ 70) × 100 = 42.9% (or approximately 43 dependents per 100 working-age people)

Answer: 42.9% (or 43:100 or 0.43:1)

Marking notes: 1 mark for identifying the correct age groups as dependents, 1 mark for correct calculation, 1 mark for correct final answer with unit/ratio format.

20.(c) [2]

Answer (model response):

One challenge that Country X might face is the increasing burden on the working-age population to support the growing elderly population (12% aged 65+). As people live longer, the government will need to spend more on healthcare, pensions, and social services for the elderly. This could lead to higher taxes or increased public spending, which may slow economic growth. Additionally, there may be a shortage of workers in certain sectors as the population ages.

Marking notes: Award 1 mark for identifying a valid challenge and 1 mark for explaining the impact. Accept other valid challenges such as pressure on healthcare, pension costs, or labour shortages.
