Answer Key and Marking Scheme

Version 3 - Map Graph Data Skills Practice

Section A: Multiple Choice Questions [10 marks]

Question 1 [1 mark] Answer: B) 4728 Explanation: Read eastings first (47), then northings (28). Students often reverse this order.

Question 2 [1 mark] Answer: B) 150m Explanation: Halfway between 140m and 160m = 140 + (160-140)/2 = 150m

Question 3 [1 mark] Answer: A) Green circles with dots Explanation: Standard OS map symbol for deciduous woodland. Coniferous forests use triangular shapes.

Question 4 [1 mark] Answer: B) 1km Explanation: Scale 1:50,000 means 1cm = 500m, so 2cm = 1000m = 1km

Question 5 [1 mark] Answer: C) Eastings to the nearest 10m Explanation: First 2 digits = grid square eastings, 3rd digit = subdivision within square (tenths)

Section B: Structured Questions [25 marks]

Question 6 [5 marks]

(a) Answer: 32°C [1 mark]

• Accept exact reading from graph

(b) Pattern description [2 marks] Sample answer: Temperature increases from 6am (24°C) to reach maximum at 2pm (32°C), then decreases towards 6pm (29°C).

• 1 mark: Identifies increase to maximum
• 1 mark: Identifies decrease after maximum OR gives specific times/temperatures

(c) Reason for highest temperature [2 marks] Sample answer: The sun is at its highest angle in the sky around midday/early afternoon, providing maximum solar radiation and heating.

• 1 mark: Reference to sun position/solar angle
• 1 mark: Link to maximum heating/radiation

Question 7 [6 marks]

(a) 6-figure grid reference [1 mark] Answer: Will vary based on map - e.g., 345567

• Must be exactly 6 figures in correct format

(b) Landform type [1 mark] Answer: Hill/Ridge/Valley (depends on contour pattern shown)

• Accept appropriate landform based on contour evidence

(c) Contour line explanation [2 marks] Sample answer: The contour lines are closer together on the eastern slope, indicating a steeper gradient. Closer contour lines mean a greater change in height over a shorter horizontal distance.

• 1 mark: Identifies closer contour lines on eastern slope
• 1 mark: Explains that closer lines = steeper gradient

(d) Route suggestion [2 marks] Sample answer: Follow the western slope where contour lines are further apart, indicating a gentler gradient that would be easier to climb.

• 1 mark: Suggests appropriate route (avoiding steepest areas)
• 1 mark: Justification based on contour evidence

Question 8 [7 marks]

(a) Best water quality site [2 marks] Answer: Site A Evidence: Highest dissolved oxygen (8.5 mg/L) OR lowest turbidity (12 NTU) OR pH closest to neutral (7.2)

• 1 mark: Correct site identification
• 1 mark: Valid evidence with specific data

(b) Dissolved oxygen pattern [2 marks] Sample answer: Dissolved oxygen decreases from upstream (Site A: 8.5 mg/L) to downstream (Site C: 4.1 mg/L), showing a clear declining trend.

• 1 mark: Identifies decreasing trend
• 1 mark: Uses specific data as evidence

(c) Reasons for increasing turbidity [3 marks] Sample answers:

• Reason 1: Urban runoff from residential areas carries sediments and particles into the river
• Reason 2: Industrial discharge adds suspended particles and pollutants to the water
• Alternative: Erosion from construction sites/reduced vegetation cover/increased human activity
• 1.5 marks per valid reason with explanation

Question 9 [7 marks]

(a) Calculation [2 marks] Working: 165 - 143 = 22 Answer: 22 litres per day

• 1 mark: Correct working shown
• 1 mark: Correct answer with units

(b) Trend description [2 marks] Sample answer: Singapore's water consumption per person shows a steady decrease from 165L in 2000 to 143L in 2020, representing a consistent downward trend over the 20-year period.

• 1 mark: Identifies decreasing trend
• 1 mark: Uses specific data/time period

(c) Reason for decrease [1 mark] Sample answers:

• Water conservation campaigns/education
• More efficient appliances/technology
• Government policies/pricing
• Public awareness of water scarcity

(d) Importance for water security [2 marks] Sample answer: Reducing consumption helps Singapore become less dependent on water imports from Malaysia and extends the lifespan of local water sources, making the country more self-sufficient and resilient to supply disruptions.

• 1 mark: Reference to reduced dependence/self-sufficiency
• 1 mark: Link to resilience/sustainability

Section C: Data Response [15 marks]

Question 10 [15 marks]

(a) Grid reference [1 mark] Answer: Will depend on map provided - e.g., 234567

• Must match the map scale and Site C location

(b) Highest bird diversity site [1 mark] Answer: Site C (18 species)

(c) Relationship description [3 marks] Sample answer: There is a negative relationship between distance from sea and crab species count. As distance from sea increases from 10m to 70m, crab species count decreases from 8 to 1 species. This shows crabs are more diverse closer to the marine environment.

• 1 mark: Identifies negative/inverse relationship
• 1 mark: Uses specific data as evidence
• 1 mark: Explains the pattern with reasoning

(d) Additional data types [4 marks] Sample answers:

• Data type 1: Vegetation height/canopy cover
• How it helps: Different bird species prefer different vegetation layers for nesting and feeding
• Data type 2: Water salinity levels
• How it helps: Salinity affects food availability which influences bird species distribution
• Alternative data: Noise levels, human disturbance, food sources, nesting sites
• 2 marks per data type (1 for appropriate data, 1 for valid explanation)

(e) Reliability evaluation and improvements [4 marks] Evaluation sample: The survey may not be reliable because it was conducted at only one time period and may not represent seasonal variations in species diversity. Improvements:

1. Repeat surveys at different times of year to account for seasonal migration
2. Increase survey duration at each site to detect more species

• 1 mark: Valid evaluation of reliability
• 1 mark: Logical improvement 1
• 1 mark: Logical improvement 2
• 1 mark: Clear explanation of how improvements increase reliability

(f) Importance for biodiversity conservation [2 marks] Sample answer: Mangrove areas provide critical habitat for many species that cannot survive elsewhere, acting as nurseries for marine life and stopover points for migratory birds, thus maintaining Singapore's overall biodiversity.

• 1 mark: Reference to unique/critical habitat function
• 1 mark: Specific example or broader conservation benefit
