Version 4 - Map Graph Data Skills Practice

Section A: Map Skills [25 marks]

Question 1 [1 mark]

Answer: 2762 Marking: 1 mark for correct 4-figure grid reference

Question 2 [1 mark]

Answer: 10m (or 10 metres) Marking: 1 mark for correct contour interval with units

Question 3 [2 marks]

Answer: 286635 (accept 285634 or 287636) Marking: 2 marks for correct 6-figure reference, 1 mark if only 4 figures given or minor error in subdivision

Question 4 [2 marks]

Sample Answer: The land in grid square 2863 is hilly/mountainous with steep slopes. The highest point is approximately 180m above sea level. The contour lines are close together indicating steep gradients. Marking: 1 mark for identifying hilly/steep terrain, 1 mark for reference to height/contour evidence

Question 5 [3 marks]

Sample Answer: From the temple (2762), head northeast following the path/road towards grid square 2863. Cross the river using the bridge at approximately 285630. Continue northeast up the hill following the contour lines to reach the viewpoint at 2965. Marking: 1 mark for correct starting direction, 1 mark for identifying river crossing, 1 mark for describing uphill route to viewpoint

Question 6 [2 marks]

Sample Answer: Working: Measure distance on map = 4.2cm. Map scale 1:50,000 means 1cm = 0.5km. Distance = 4.2 × 0.5 = 2.1km Answer: 2.1km Marking: 1 mark for correct working/method, 1 mark for correct final answer

Question 7 [3 marks]

Sample Answer: The settlement follows the river valley and main road network. Linear settlements develop along transport routes for accessibility. The steep terrain on either side of the valley restricts building, forcing development into a linear pattern along the flat valley floor. Marking: 1 mark for identifying river/road influence, 1 mark for explaining accessibility advantage, 1 mark for explaining terrain constraints

Question 8 [3 marks]

Sample Answer: The forest is located on steep slopes (close contour lines) making development difficult and expensive. It may be a water catchment area protecting water quality. The forest provides habitat for wildlife and prevents soil erosion on the steep terrain. Marking: 1 mark each for any three valid reasons (steep terrain, water catchment, wildlife habitat, erosion prevention, recreation value)

Section B: Data Interpretation [15 marks]

Question 9 [2 marks]

Answer: Site: D, Value: 8.5 mg/L Marking: 1 mark for correct site, 1 mark for correct value with units

Question 10 [3 marks]

Sample Answer: Site D (forest stream) has better water quality than Site A (urban stream). Site D has higher dissolved oxygen (8.5 mg/L vs 4.2 mg/L), lower turbidity (2 NTU vs 15 NTU), and more neutral pH (6.8 vs 5.9). This indicates less pollution and healthier aquatic conditions in the forest environment. Marking: 1 mark for stating which site has better quality, 2 marks for using specific data evidence to support comparison

Question 11 [2 marks]

Sample Answer: Site B may be located downstream of construction activity or urban runoff, causing increased suspended particles. Agricultural activities or soil erosion from nearby land use could also increase turbidity. Marking: 2 marks for logical explanation linking human activity to increased suspended particles

Question 12 [4 marks]

Sample Answer: All three stations show temperature increase from 6am to peak around 2-3pm, then decrease toward 6pm. Station 1 (urban) has the highest temperatures throughout, reaching 32°C at peak. Station 2 (suburban) shows moderate temperatures peaking at 29°C. Station 3 (forest) remains coolest, peaking at 26°C. The urban heat island effect is clearly demonstrated. Marking: 1 mark for describing general pattern, 1 mark each for describing each station's specific pattern, 1 mark for explaining urban heat island effect

Question 13 [4 marks]

Sample Answer: Take multiple readings at each site and calculate averages to reduce random errors. Repeat the investigation at different times/seasons to account for temporal variation. Use calibrated equipment and standardized measurement procedures. Increase the number of sampling sites to better represent the area being studied. Marking: 1 mark each for four valid improvements (repeated measurements, temporal replication, equipment calibration, increased sample size, standardized methods)

Section C: Graph Analysis and Application [10 marks]

Question 14 [2 marks]

(a) 2000: 165 litres (b) 2020: 141 litres Marking: 1 mark each for correct readings from graph

Question 15 [4 marks]

Sample Answer: Singapore's daily water consumption per person decreased steadily from 165 litres in 2000 to 141 litres in 2020, a reduction of 24 litres (14.5%). The steepest decline occurred between 2000-2010, falling from 165L to 150L. From 2010-2020, the decrease was more gradual, dropping from 150L to 141L. Overall, the trend shows successful water conservation efforts over the 20-year period. Marking: 1 mark for identifying decreasing trend, 1 mark for using specific figures, 1 mark for describing rate of change, 1 mark for overall evaluation

Question 16 [4 marks]

Sample Answer: Reason 1: Government water conservation campaigns and education programs encouraged citizens to reduce water usage through behavioral changes like shorter showers and fixing leaks.

Reason 2: Introduction of water-efficient technologies such as low-flow taps, dual-flush toilets, and water recycling systems in buildings reduced per capita consumption. Marking: 2 marks each for two well-explained reasons (government policy, technology, pricing, education, efficiency improvements, public awareness)
