Subject: Geography | Level: Secondary 4 | Version: 4 of 5 Topic: Map, Graph & Data Skills | Total Marks: 50
Section A: Map Reading & Interpretation
Question 1
(a) Give the four-figure grid reference of the school. [1]
Answer: 2416
Method: Read the easting (first two digits: 24) then the northing (last two digits: 16) from the grid square in which the school is located.
(b) What is the height of the trigonometrical station at grid reference 228155? [1]
Answer: 45 m
Method: The spot height is given directly next to the trigonometrical station symbol on the map.
(c) State the compass direction of the housing estate from the reservoir. [1]
Answer: North-east
Method: From the reservoir at 2114, the housing estate (2316–2416) lies to the north and east. The combined compass direction is north-east.
(d) Describe the relief in grid square 2315. [2]
Answer: The land in grid square 2315 is hilly. Contour lines are closely spaced, indicating steep slopes. The elevation rises from approximately 20 m in the south of the square to over 40 m in the north. A river flows through the lower ground in the southern part of the square, suggesting a valley. [2 marks: 1 for identifying hilly/steep terrain, 1 for referencing contour spacing or elevation change]
Marking notes: Award 1 mark for stating the land is hilly/steely elevated. Award 1 mark for describing evidence (close contour lines, elevation range, or river valley). Do not award marks for vague answers like "the land is high" without supporting detail.
(e) Measure the straight-line distance between the trigonometrical station (228155) and the school (245162). Show your working. [2]
Answer:
- Horizontal distance: from easting 22 to 24.5 = 2.5 km (each grid square = 1 km)
- Alternatively, using a ruler on the map: measure the straight-line distance on the map (e.g., 2.7 cm), then use the scale bar to convert.
- If the scale is 1 cm : 1 km, and the measured distance is 2.7 cm, then actual distance = 2.7 km.
Accept answers in the range 2.5–2.9 km depending on measurement precision.
[2 marks: 1 for correct method/working shown, 1 for correct answer within acceptable range]
Marking notes: Award 1 mark for showing a valid measurement method (ruler + scale, or grid reference calculation). Award 1 mark for the correct answer. Allow ±0.2 km tolerance.
Question 2
(a) Name the coastal landform at A and at C. [2]
Answer:
- A: Cliff (or headland) [1]
- C: Beach [1]
(b) Explain how the spit at B is formed. [3]
Answer:
The spit is formed by longshore drift. Waves approach the coast from the southwest at an angle (oblique). Swash carries sediment (sand and shingle) up the beach at an angle, and backwash carries it straight back down due to gravity. This zig-zag movement transports sediment along the coast. When the coastline changes direction at headland B, the sediment is deposited in the sheltered, calmer water. Over time, the deposited material builds up above sea level, forming a narrow ridge of sand and shingle extending from the headland — a spit. [3 marks: 1 for identifying longshore drift, 1 for describing the process (swash/backwash or zig-zag movement), 1 for explaining deposition at the change in coastline direction]
Marking notes: Students must mention longshore drift to gain full marks. Answers that only describe "waves depositing sediment" without explaining the transport mechanism receive a maximum of 1 mark.
(c) Suggest one reason why the area between headlands A and B may be suitable for a harbour. [1]
Answer: The bay between the two headlands is sheltered from strong waves and winds, providing calm, protected water for ships to anchor safely. [1 mark]
Accept any valid reason: sheltered/calm waters, natural protection from waves, deep water near shore, etc.
Section B: Graph & Data Interpretation
Question 3
(a) Describe the temperature pattern of Medan. [2]
Answer:
Medan experiences high temperatures throughout the year, ranging from 26°C to 27.5°C. The temperature remains relatively constant with only a small annual range of about 1.5°C. The warmest months are April and May (around 27.5°C), while the coolest months are January and December (around 26°C). [2 marks: 1 for stating high/consistently warm temperatures, 1 for describing the small range or specific values]
(b) Describe the rainfall pattern of Medan. [2]
Answer:
Medan receives high annual rainfall of approximately 1950 mm. Rainfall varies throughout the year, with the wettest months being October (250 mm) and November (240 mm). The driest months are February (100 mm) and July (110 mm). There are two noticeable peaks in rainfall around April–May and September–November. [2 marks: 1 for stating high annual rainfall with figure, 1 for describing seasonal variation/peaks]
(c) Account for the climate characteristics of Medan. [3]
Answer:
Medan is located near the equator (approximately 3°N latitude) in Indonesia. Because of its equatorial location, it receives intense solar radiation throughout the year, resulting in consistently high temperatures with little seasonal variation. The high temperatures cause strong convection currents, leading to frequent convectional rainfall. The movement of the Inter-Tropical Convergence Zone (ITCZ) over the area during different seasons brings periods of enhanced rainfall, creating the two rainfall peaks. Additionally, the influence of monsoon winds — the southwest monsoon brings moist air from the ocean, increasing rainfall, while the northeast monsoon is relatively drier. [3 marks: 1 for equatorial location and high solar radiation, 1 for convectional rainfall explanation, 1 for ITCZ or monsoon influence]
Marking notes: Award marks for relevant geographical concepts. Reference to latitude, ITCZ, convection, or monsoon each counts as a valid point. Maximum 3 marks.
Question 4
(a) Which country contributed the highest number of tourist arrivals? [1]
Answer: Indonesia (3.2 million)
(b) Calculate the total number of tourist arrivals from all five countries. [2]
Answer:
3.2 + 2.8 + 1.5 + 1.2 + 0.9 = 9.6 million
[2 marks: 1 for correct method/addition, 1 for correct answer]
(c) Indonesia and Malaysia together accounted for what percentage of the total? [2]
Answer:
Indonesia + Malaysia = 3.2 + 1.2 = 4.4 million
Percentage = (4.4 ÷ 9.6) × 100 = 45.8% (accept 45.83% or 46%)
[2 marks: 1 for correct addition of Indonesia + Malaysia, 1 for correct percentage calculation]
(d) Suggest two reasons why Indonesia is the top source of tourists to Singapore. [2]
Answer:
- Geographical proximity: Indonesia is very close to Singapore (short flight/ferry distance), making it convenient and affordable for Indonesians to travel to Singapore. [1]
- Strong economic and cultural ties: There are established trade links, business connections, and cultural similarities between Indonesia and Singapore, encouraging frequent travel for business, shopping, and leisure. [1]
Accept any two valid reasons: proximity, affordable transport, business links, cultural ties, medical tourism, education, family visits, etc.
Question 5
(a) Calculate the annual temperature range for London. [2]
Answer:
Highest temperature: 18°C (July/August)
Lowest temperature: 5°C (January/February)
Range = 18 − 5 = 13°C
[2 marks: 1 for identifying highest and lowest values, 1 for correct subtraction]
(b) Compare the temperature pattern of London with that of Medan. [3]
Answer:
London has a much greater annual temperature range (13°C) compared to Medan (1.5°C). London's temperatures vary significantly across the year, from 5°C in winter to 18°C in summer, whereas Medan's temperatures remain consistently high between 26°C and 27.5°C. London experiences distinct seasons with cold winters and warm summers, while Medan has no distinct seasons and remains hot throughout the year. London's temperatures peak in July–August (summer in the Northern Hemisphere), while Medan's temperatures are highest in April–May. [3 marks: 1 for comparing temperature ranges, 1 for comparing seasonal variation, 1 for a specific data comparison or seasonal contrast]
(c) Explain why London experiences greater annual temperature variation than Medan. [2]
Answer:
London is located at a high latitude (approximately 51°N) in the Northern Hemisphere. At this latitude, the angle of the sun varies significantly between summer and winter. In summer, the sun is higher in the day is longer, resulting in warmer temperatures. In winter, the sun is lower and days are shorter, leading to much cooler temperatures. Medan, being near the equator (3°N), receives nearly direct sunlight year-round with little variation in day length, so temperatures remain consistently high. [2 marks: 1 for explaining latitude effect on solar angle/seasonality for London, 1 for contrasting with equatorial location of Medan]
Section C: Data Response & Application
Question 6
(a) Which region has the highest population density? [1]
Answer: South (450 per km²)
(b) Describe the relationship between population density and type of main economic activity. [3]
Answer:
There is a clear relationship between population density and economic activity. Regions with higher population densities tend to have manufacturing or services as their main economic activity (South: 450/km², manufacturing; West: 380/km², services). These activities are typically urban-based and attract large numbers of workers. Regions with lower population densities tend to have primary economic activities such as agriculture (North: 12/km²) and fishing (East: 85/km²), which require more land and are typically rural. This suggests that as economic activities shift from primary to secondary and tertiary sectors, population density increases. [3 marks: 1 for identifying the general trend, 1 for using specific data/examples from the table, 1 for explaining the urban-rural or sector-based relationship]
Marking notes: Students must describe the relationship using data from the table. Generic statements without data reference receive a maximum of 1 mark.
(c) Suggest two reasons why the South region has a high population density. [2]
Answer:
- The manufacturing sector provides many job opportunities, attracting workers and their families to live in the region. [1]
- Manufacturing industries are typically located in urban areas with developed infrastructure (housing, transport, utilities), which supports a high concentration of people. [1]
Accept any two valid reasons: employment opportunities, urban infrastructure, industrial development, migration, availability of services, etc.
Question 7
(a) What type of river valley is shown? [1]
Answer: V-shaped valley
(b) Using evidence from Figure 6, describe two features of this river valley. [2]
Answer:
- The valley has steep sides — the elevation rises from 20 m at the river bank to 80 m at the valley rim over only 100 m horizontal distance, indicating very steep slopes. [1]
- The valley floor is narrow — the river channel is only 2 m wide, and there is no floodplain, indicating the valley has not been widened by lateral erosion. [1]
Accept other valid features: V-shape cross-profile, close contour lines on valley sides, absence of floodplain, narrow valley floor.
(c) Explain how the river has shaped the valley. [3]
Answer:
The river has shaped the valley primarily through vertical (downward) erosion. In the upper course of a river, the gradient is steep, giving the river high kinetic energy. The river erodes downwards into its bed through processes such as hydraulic action (force of water breaking apart rock), abrasion (sediment carried by the river scraping against the bed and banks), and corrosion (chemical dissolution of rock). This deepens the valley, creating the characteristic V-shape. Because the river is in its early stage, there is limited lateral (sideways) erosion, so the valley remains narrow with no floodplain. [3 marks: 1 for identifying vertical/downward erosion, 1 for naming at least one erosion process, 1 for explaining the resulting V-shape/narrow valley]
(d) Predict how this valley might change over a long period of time. Give a reason. [2]
Answer:
Over a long period of time, the valley will become wider and less steep. As the river continues to erode, lateral erosion will become more dominant, undercutting the valley sides and causing them to retreat. Weathering and mass movement (e.g., slumping, landslides) will also wear back the valley sides. The valley will gradually change from a V-shape to a broader, flatter shape, and a floodplain may develop as the river deposits sediment during floods. [2 marks: 1 for predicting widening/broadening of the valley, 1 for a valid reason involving lateral erosion, weathering, or mass movement]
Marking notes: Accept answers that describe the valley becoming wider, developing a floodplain, or becoming less steep, provided a valid geographical reason is given.
