Answer Key and Marking Scheme

Paper: Map, Graph & Data Skills
Version: 1 of 5
Total Marks: 50

Section A: Map Reading and Interpretation (15 marks)

Question 1 (3 marks)

(a) State the four-figure grid reference of the lighthouse shown on the map. [1]

Answer: 4523 (or equivalent based on map extract provided)

Marking note: Award 1 mark for correct four-figure grid reference. Accept any answer within one grid square of the correct location if map reading is reasonable.

(b) Measure the straight-line distance, in kilometres, between the jetty at Point A and the summit of Bukit Tinggi (Point B). [1]

Answer: 3.2 km (accept 3.0–3.4 km depending on measurement precision)

Marking note: Award 1 mark for correct distance with appropriate units (km). Accept minor variation due to measurement technique. Must include units for the mark.

(c) Describe the relief of the area shown in the map extract. [1]

Answer: The area has a coastal plain in the west/southwest with low-lying flat land, rising to hilly terrain in the east/northeast with Bukit Tinggi as the highest point (or equivalent description based on map).

Marking note: Award 1 mark for a description that identifies both lowland and highland areas, or describes the general pattern of relief. Simple statements such as "there are hills" without reference to location or pattern = 0 marks.

Question 2 (4 marks)

(a) Identify the direction of the river flow along Sungai Raya. Support your answer with map evidence. [2]

Answer: The river flows from northeast to southwest (or from the hilly interior towards the coast). Map evidence: the river originates in the higher ground near Bukit Tinggi (indicated by contour lines) and flows towards the lower coastal plain; the tributaries join the main river in a downstream direction; the river mouth is located at the coast.

Marking note:

1 mark for correct direction of flow.
1 mark for valid map evidence (contour lines showing higher elevation at source, river mouth at coast, or tributary pattern).
Award 0 marks if direction is stated without evidence.

(b) Explain why there is a concentration of settlements along the coastal plain rather than in the hilly interior. [2]

Answer: The coastal plain provides flat land that is easier to build on compared to the steep slopes of the hilly interior. The coastal area also offers access to the sea for fishing and transport, and the flat land is more suitable for agriculture and infrastructure development. In contrast, the hilly interior has steep slopes that make construction difficult and limit accessibility.

Marking note:

Award 1 mark for each valid reason, up to a maximum of 2 marks.
Acceptable reasons include: flat land for building, access to sea/coast for livelihood, easier transport links, fertile coastal soils, difficulty of building on steep slopes, limited accessibility in hills.
Answers must include explanation, not just description.

Question 3 (4 marks)

(a) State a suitable hypothesis for this investigation. [1]

Answer: "Slope gradient affects the type of land use, with steeper slopes being used for forest/conservation and gentler slopes being used for settlement and agriculture." (Accept any reasonable hypothesis linking slope gradient to land use.)

Marking note: Award 1 mark for a testable hypothesis that clearly states a relationship between slope gradient and land use. Hypotheses stated as questions = 0 marks.

(b) Describe how the student could measure slope gradient at five different locations in the study area. [3]

Answer: The student could use a clinometer (or digital inclinometer) to measure slope angle. At each location, the student should:

Select five sites representing different slope conditions (e.g., coastal plain, gentle slope, moderate slope, steep slope, hill summit).
At each site, place two ranging poles a known distance apart (e.g., 10 metres) along the slope.
Use the clinometer to sight from the top of one pole to the top of the other, reading the slope angle in degrees.
Record the measurement and repeat at least twice at each site to calculate an average for reliability.
Record the GPS coordinates or grid reference of each measurement site.

Marking note:

1 mark for identifying the instrument (clinometer/inclinometer).
1 mark for describing the measurement procedure (use of ranging poles, sighting, reading angle).
1 mark for mentioning reliability measures (repeating measurements, averaging) or site selection strategy.
Vague descriptions without specific instruments or procedures = maximum 1 mark.

Question 4 (4 marks)

(a) With reference to both the photograph and the map, describe two differences between the information provided by the photograph and the information provided by the map. [2]

Answer:

The photograph shows the actual appearance of buildings, vegetation, and landscape features (what the place looks like), while the map uses symbols and colours to represent these features.
The photograph provides a ground-level or oblique perspective view, while the map provides a plan (bird's eye) view showing the layout and spatial relationships accurately.
The map shows features that may not be visible in the photograph (e.g., contour lines showing elevation, grid references, scale), while the photograph shows details like building colours and conditions that are not on the map.

Marking note:

Award 1 mark for each clearly explained difference (maximum 2 marks).
Differences must reference both photograph and map.
Accept any two valid differences.

(b) Explain why a geographer would use both photographs and maps when studying a coastal settlement. [2]

Answer: Photographs provide visual detail and a realistic view of the settlement's appearance, land use, and environmental conditions that help geographers understand the character of the place. Maps provide accurate spatial information such as exact locations, distances, areas, and the relationship between different features, which photographs cannot show precisely. Using both allows the geographer to combine visual interpretation with precise spatial analysis for a more complete understanding.

Marking note:

1 mark for explaining the value of photographs (visual detail, realistic representation, shows conditions).
1 mark for explaining the value of maps (spatial accuracy, measurements, relationships between features).
Answers must explain why both are needed, not just describe each.

Section B: Graph and Data Interpretation (20 marks)

Question 5 (4 marks)

(a) Calculate the annual temperature range for Station X and Station Y. [2]

Answer:

Station X: Annual temperature range = Highest monthly temperature − Lowest monthly temperature (e.g., 28°C − 26°C = 2°C)
Station Y: Annual temperature range = Highest monthly temperature − Lowest monthly temperature (e.g., 22°C − 2°C = 20°C)

Marking note:

1 mark for each correct calculation with appropriate units (°C).
Award marks based on correct method even if exact values depend on the provided figure.
No units = deduct 1 mark overall.

(b) Describe the main differences in the rainfall patterns between Station X and Station Y. [2]

Answer: Station X (tropical) shows rainfall throughout the year with high monthly totals and no distinct dry season, typical of an equatorial climate. Station Y (temperate) shows seasonal variation in rainfall, with wetter months in summer and drier months in winter, or rainfall distributed more evenly but with lower totals than Station X.

Marking note:

1 mark for describing Station X's pattern (rainfall throughout year, high totals, no dry season).
1 mark for describing Station Y's pattern (seasonal variation, lower totals, distinct wet/dry periods).
Answers must compare both stations, not describe each in isolation.

Question 6 (4 marks)

(a) Suggest how the students could present the data for all three attractions on one graph to show the changes over time. [2]

Answer: The students could use a multiple line graph (or compound line graph). The x-axis would show the six months (time), and the y-axis would show the number of visitors. Three separate lines, each in a different colour or pattern, would represent the three attractions. A clear legend would identify which line corresponds to which attraction, and both axes would be clearly labelled with units.

Marking note:

1 mark for identifying an appropriate graph type (multiple line graph, compound line graph).
1 mark for describing how to construct it (axes, legend, multiple lines).
Bar chart is acceptable but must explain how all three attractions are shown for comparison (e.g., grouped bar chart).

(b) Explain one advantage of using the graph type you have suggested. [2]

Answer: A multiple line graph allows easy visual comparison of trends over time for all three attractions simultaneously. The reader can quickly see which attraction had the highest visitor numbers in each month, identify seasonal patterns, and compare the rate of increase or decrease between attractions. This would be more difficult to see if the data were presented in a table alone.

Marking note:

1 mark for stating the advantage.
1 mark for explaining why this advantage is useful (linking to comparison, trend identification, or clarity).
Generic answers without explanation = maximum 1 mark.

Question 7 (4 marks)

(a) Describe the general relationship shown in the scatter graph. Support your answer with data. [2]

Answer: There is a positive correlation between GDP per capita and CO₂ emissions per capita — countries with higher GDP per capita tend to have higher CO₂ emissions per capita. For example, Country A with a GDP per capita of US $50,000 has CO₂ emissions of 15 tonnes per capita, while Country B with a GDP per capita of US$ 5,000 has CO₂ emissions of only 1 tonne per capita.

Marking note:

1 mark for identifying the positive correlation/relationship.
1 mark for supporting with specific data from the graph (must reference at least two data points or a clear range).
Vague descriptions without data support = maximum 1 mark.

(b) Identify one country that does not follow the general trend. Suggest a possible reason for this anomaly. [2]

Answer: Country C (e.g., a country with high GDP but low emissions, such as a service-based economy, or a country with low GDP but high emissions, such as an oil-producing nation). Possible reason: Country C may have an economy based on services and technology rather than heavy industry, resulting in lower emissions despite high GDP. Alternatively, an oil-producing country may have high emissions from extraction and flaring despite lower GDP per capita.

Marking note:

1 mark for identifying an anomalous country with brief description of how it deviates.
1 mark for a plausible reason (economic structure, energy sources, environmental policies, population factors).
Reason must be linked to the specific anomaly identified.

Question 8 (4 marks)

(a) Describe how the student could calculate a weighted satisfaction score for "Bus Frequency" to obtain a single numerical value. [2]

Answer: Assign a numerical weight to each response category: Very Satisfied = +2, Satisfied = +1, Neutral = 0, Dissatisfied = −1, Very Dissatisfied = −2. Multiply the number of respondents in each category by the corresponding weight. Sum all the weighted values to obtain the total weighted score. A positive total score indicates overall satisfaction, while a negative score indicates overall dissatisfaction.

Marking note:

1 mark for assigning appropriate numerical weights to the Likert scale categories.
1 mark for describing the calculation method (multiply frequency by weight, sum the products).
Alternative weighting schemes are acceptable if logically consistent.

(b) Using the weighted score method you described, explain which aspect of public transport received the highest satisfaction rating. [2]

Answer: Based on the data in Table 2, "Bus Frequency" received a weighted score of +45, "Bus Punctuality" received +28, and "Bus Comfort" received +12. Therefore, "Bus Frequency" received the highest satisfaction rating, as it has the highest positive weighted score, indicating that more respondents were satisfied or very satisfied with this aspect compared to the others.

Marking note:

1 mark for correct identification of the aspect with the highest score (based on provided table data).
1 mark for explaining using the weighted score values (comparative explanation).
Answers must reference the calculated scores, not just state the answer.

Question 9 (4 marks)

(a) Compare the proportion of land used for residential purposes in Neighbourhood A and Neighbourhood C. [2]

Answer: Neighbourhood A has a higher proportion of land used for residential purposes (approximately 60%) compared to Neighbourhood C (approximately 35%). The difference is about 25 percentage points, indicating that Neighbourhood A is more residential in character while Neighbourhood C has a more mixed land use pattern.

Marking note:

1 mark for stating which neighbourhood has the higher proportion (with approximate percentages).
1 mark for quantifying the difference or making a comparative statement about land use character.
Answers must use data from the graph.

(b) Neighbourhood B has the highest proportion of land used for parks and green spaces. Suggest one social benefit and one environmental benefit of this land use pattern for residents. [2]

Answer:

Social benefit: Parks and green spaces provide recreational areas for residents to exercise, socialise, and relax, which improves physical and mental well-being and fosters community interaction.
Environmental benefit: Green spaces help reduce the urban heat island effect by providing shade and cooling through evapotranspiration; they also improve air quality by absorbing carbon dioxide and filtering pollutants; they provide habitats for urban wildlife and support biodiversity.

Marking note:

1 mark for a valid social benefit (recreation, health, community interaction, quality of life).
1 mark for a valid environmental benefit (temperature regulation, air quality, biodiversity, water absorption).
Benefits must be clearly distinguished as social or environmental.

Section C: Data Response and Evaluation (15 marks)

Question 10 (8 marks)

(a) Describe the global distribution of earthquakes shown in Figure 6. [2]

Answer: Earthquakes are not randomly distributed but are concentrated in narrow belts or zones. The main concentrations are along the Pacific Ring of Fire (surrounding the Pacific Ocean), the Alpine-Himalayan Belt (from the Mediterranean through the Middle East to Southeast Asia), and along mid-ocean ridges such as the Mid-Atlantic Ridge. There are relatively few earthquakes in the interiors of continents away from plate boundaries.

Marking note:

1 mark for identifying the concentration in belts/zones (not random).
1 mark for naming at least two specific zones (Pacific Ring of Fire, Alpine-Himalayan Belt, mid-ocean ridges).
Vague descriptions without specific locations = maximum 1 mark.

(b) Explain the relationship between earthquake distribution and tectonic plate boundaries. [3]

Answer: Earthquakes occur predominantly along tectonic plate boundaries because these are zones where plates interact. At convergent boundaries, plates collide, and the subduction of one plate beneath another generates friction and stress that is released as earthquakes. At divergent boundaries, plates move apart, creating fractures where earthquakes occur. At transform boundaries, plates slide past each other, causing friction and earthquakes. The concentration of earthquakes along the Pacific Ring of Fire corresponds to the convergent and transform boundaries surrounding the Pacific Plate, while earthquakes along the Mid-Atlantic Ridge correspond to the divergent boundary between the Eurasian/North American and South American/African plates.

Marking note:

1 mark for stating that earthquakes occur mainly at plate boundaries.
1 mark for explaining the mechanism at one type of boundary (convergent, divergent, or transform).
1 mark for linking to specific examples from Figure 6 or providing a second boundary type explanation.
Answers must explain causation, not just describe correlation.

(c) Using the data in the table, calculate the total number of earthquakes of magnitude 6.0 and above recorded over the 10-year period. [1]

Answer: Total = (Number of magnitude 6.0–6.9) + (Number of magnitude 7.0–7.9) + (Number of magnitude 8.0+) = [sum based on table data provided]

Marking note: Award 1 mark for correct calculation. Method must be shown or implied. Accept minor arithmetic errors if method is correct.

(d) A student claims that "Earthquakes of magnitude 8.0 and above cause the most damage globally." Using evidence from Figure 6 and your own knowledge, evaluate the reliability of this claim. [2]

Answer: The claim is partially reliable but oversimplified. While magnitude 8.0+ earthquakes release enormous energy and can cause widespread devastation (e.g., 2011 Tohoku earthquake), the damage caused depends on multiple factors beyond magnitude alone. Evidence from Figure 6 shows that magnitude 8.0+ earthquakes are relatively rare compared to smaller earthquakes. However, a magnitude 7.0 earthquake near a densely populated urban area with poor building standards (e.g., 2010 Haiti earthquake) can cause more damage and casualties than a magnitude 8.0+ earthquake in a remote area or a well-prepared country. Therefore, magnitude alone does not determine damage; factors such as population density, level of development, building codes, depth of focus, and distance from the epicentre are equally or more important.

Marking note:

1 mark for acknowledging that the claim has some validity (high-magnitude earthquakes release more energy and can cause severe damage).
1 mark for explaining why the claim is not fully reliable (other factors affect damage: location, depth, population density, preparedness, building standards).
Answers must include evaluation (both sides), not just agreement or disagreement.
Reference to Figure 6 evidence strengthens the answer.

Question 11 (7 marks)

(a) Describe the trend in dissolved oxygen levels along the river. Support your answer with data from the table. [2]

Answer: Dissolved oxygen levels decrease consistently from upstream to downstream. At Site 1 (forested area, 0 km from source), the DO level is 8.5 mg/L. This decreases steadily to 7.8 mg/L at Site 2, 6.2 mg/L at Site 3, 4.5 mg/L at Site 4, and reaches the lowest level of 3.1 mg/L at Site 5 (industrial zone, 8 km from source). The total decrease is 5.4 mg/L over the 8 km distance.

Marking note:

1 mark for identifying the decreasing trend.
1 mark for supporting with specific data (at least two data points or the range of decrease).
Vague descriptions without data = maximum 1 mark.

(b) Explain why dissolved oxygen levels decrease as the river flows through the urban area. [3]

Answer: As the river flows through the urban area, it receives pollutants from various sources that reduce dissolved oxygen levels. Organic pollutants (e.g., sewage, food waste) are decomposed by bacteria, which consume oxygen during the decomposition process (biochemical oxygen demand). Industrial effluents may contain chemicals that directly reduce oxygen or promote algal blooms that later die and decompose, further depleting oxygen. Urban runoff from roads and residential areas carries oils, chemicals, and sediments that can also reduce oxygen levels. The increasing intensity of urban land use from residential to commercial to industrial corresponds with greater pollutant inputs, explaining the progressive decline in DO levels from Site 2 to Site 5.

Marking note:

1 mark for identifying pollutant inputs from urban areas as the cause.
1 mark for explaining the mechanism of oxygen depletion (bacterial decomposition, BOD, chemical reactions).
1 mark for linking to the specific land use changes along the river (residential → commercial → industrial) or providing a second mechanism.
Answers must explain the process, not just state that pollution reduces oxygen.

(c) Evaluate the reliability of the students' data collection method. [2]

Answer: The data collection method has some strengths but also limitations that affect reliability. Strengths: The students collected data at five sites along the river, providing a spatial comparison; they recorded surrounding land use, which helps explain the results; the measurements show a clear and consistent trend, suggesting internal consistency. Limitations: The table does not indicate whether measurements were repeated at each site (lack of replication reduces reliability); there is no information about the time of day or weather conditions when measurements were taken (these can affect DO levels); the instrument used is not specified (uncalibrated instruments produce unreliable data); only one parameter (DO) was measured, limiting the ability to cross-validate findings. Overall, the method provides useful indicative data but could be improved by taking multiple readings at each site, controlling for time and weather, and using calibrated instruments.

Marking note:

1 mark for identifying at least one strength or one limitation with explanation.
1 mark for a balanced evaluation (acknowledging both strengths and limitations) or for a second well-explained point.
Answers that only list strengths or only list limitations = maximum 1 mark.
Must evaluate reliability specifically, not just describe the method.
