Secondary 1 Geography Quiz - Map Graph Data Skills (Answer Key)

Total Marks: 40 marks

Section A: Map Skills [10 marks]

Question 1 [1 mark] State the 4-figure grid reference of the radio mast shown on the map.

Answer: 2947 Marking: Accept exact grid reference only. Common error: reversing easting/northing order.

Question 2 [1 mark] What is the contour interval shown on this map?

Answer: 10m / 10 metres Marking: Accept "10m" or "10 metres". Do not accept without units.

Question 3 [2 marks] State the 6-figure grid reference of the school located in grid square 2847 and identify two types of vegetation shown in the map legend.

Answer: 6-figure grid reference: 285475 (accept 284476 or similar within reasonable estimation) Vegetation types: (i) Deciduous woodland / Forest (ii) Coniferous woodland / Orchard Marking: 1 mark for grid reference (accept answers within ±1 for final digits), 1 mark for two correct vegetation types from legend.

Question 4 [3 marks] Using evidence from the map, describe the relief of the area between grid lines 28 and 30.

Sample Answer: The area has varied relief with hills and valleys. The highest point is approximately 180m above sea level, while the lowest areas are around 40m. The contour lines show steep slopes in some areas and gentler gradients near the river valley. Marking: 1 mark for describing height variation with evidence, 1 mark for describing slope characteristics, 1 mark for specific reference to contour evidence.

Question 5 [3 marks] Calculate the straight-line distance between the church at grid reference 285473 and the bridge at grid reference 295481.

Working: Distance on map = measure between two points ≈ 1.2 cm Map scale = 1:50,000 Actual distance = 1.2 × 50,000 = 60,000 cm = 0.6 km

Answer: 0.6 km Marking: 1 mark for correct measurement, 1 mark for correct scale conversion, 1 mark for final answer with units.

Section B: Data Interpretation [10 marks]

Question 6 [1 mark] Which site has the highest water temperature?

Answer: Site C Marking: Accept "C" or "Site C" only.

Question 7 [2 marks] Compare the dissolved oxygen levels between Site A and Site C.

Sample Answer: Site A has much higher dissolved oxygen (8.5 mg/L) compared to Site C (4.1 mg/L). Site A has more than double the dissolved oxygen level of Site C. Marking: 1 mark for stating both values, 1 mark for making comparison with quantitative evidence.

Question 8 [3 marks] Using evidence from the table, describe the pattern of water quality from upstream to downstream.

Sample Answer: Water quality generally deteriorates from upstream to downstream. Site A (upstream) has the best quality with high dissolved oxygen (8.5 mg/L) and low turbidity (2.1 NTU). Site C (industrial area) has the poorest quality with lowest dissolved oxygen (4.1 mg/L) and highest turbidity (15.3 NTU). Site D shows some recovery with improved dissolved oxygen (7.8 mg/L) and lower turbidity (3.4 NTU). Marking: 1 mark for identifying overall pattern, 1 mark for using specific data evidence, 1 mark for noting variation/recovery at Site D.

Question 9 [2 marks] Suggest one reason why Site C has the poorest water quality.

Sample Answer: Site C is located in an industrial area, so factories may discharge polluted water or chemicals into the river, reducing dissolved oxygen and increasing turbidity. Marking: 1 mark for identifying industrial pollution source, 1 mark for explaining the impact on water quality indicators.

Question 10 [2 marks] Explain why dissolved oxygen is an important indicator of water quality.

Sample Answer: Dissolved oxygen is essential for aquatic life such as fish and other organisms to survive. High dissolved oxygen levels indicate healthy water that can support biodiversity, while low levels suggest pollution or organic waste. Marking: 1 mark for linking to aquatic life, 1 mark for explaining healthy water indication or pollution impact.

Section C: Graph Analysis [10 marks]

Question 11 [1 mark] State Singapore's daily water consumption per person in 2010.

Answer: 155 litres (accept 154-156 litres) Marking: Accept reading within reasonable range due to graph interpretation.

Question 12 [2 marks] Describe the trend in water consumption from 2000 to 2020.

Sample Answer: Water consumption per person decreased steadily from 165 litres in 2000 to 143 litres in 2020, showing a consistent downward trend over the 20-year period. Marking: 1 mark for identifying decreasing trend, 1 mark for using specific data values.

Question 13 [2 marks] Calculate the percentage decrease in water consumption between 2000 and 2020.

Working: 2000: 165 litres, 2020: 143 litres Decrease = 165 - 143 = 22 litres Percentage decrease = (22 ÷ 165) × 100 = 13.3%

Answer: 13.3% Marking: 1 mark for correct calculation method, 1 mark for correct final answer.

Question 14 [3 marks] Suggest two reasons for the trend shown in the graph.

Sample Answers: Reason 1: Singapore has implemented water conservation campaigns and policies to encourage people to use water more efficiently, such as water-saving devices and public education about water scarcity. Reason 2: Introduction of water pricing policies and NEWater technology has made people more conscious of water usage and provided alternative water sources. Marking: 1.5 marks per reason (1 mark for identifying reason, 0.5 mark for explanation).

Question 15 [2 marks] Explain why monitoring water consumption data is important for Singapore.

Sample Answer: Singapore has limited freshwater resources and relies on imported water and technology like desalination. Monitoring consumption helps the government plan water supply and implement conservation measures to ensure water security. Marking: 1 mark for identifying Singapore's water constraints, 1 mark for explaining planning/policy benefits.

Section D: Application Skills [10 marks]

Question 16 [2 marks] A group of students wants to test water quality at a new site. Describe one method they could use to collect reliable data.

Sample Answer: Take multiple water samples from different points at the same site and test each sample separately, then calculate the average to reduce errors and ensure accuracy. Marking: 1 mark for method, 1 mark for explanation of reliability.

Question 17 [2 marks] Explain why the settlement pattern shown on the map is described as linear.

Sample Answer: The settlement pattern is linear because the buildings and houses are arranged in a line along the main road/river. This creates a ribbon-like development pattern rather than clustered or scattered settlements. Marking: 1 mark for identifying linear arrangement, 1 mark for explaining the reason (along transport route/river).

Question 18 [3 marks] Describe three physical features that can be identified using map symbols.

Sample Answers: (i) River - shown as blue line flowing through the area (ii) Hill/elevated land - shown by contour lines and spot heights (iii) Woodland/forest - shown by green shaded areas with tree symbols Marking: 1 mark each for correctly identifying and describing physical features with reference to symbols.

Question 19 [2 marks] Predict the likely water consumption per person in 2025 based on the trend shown and justify your answer.

Sample Answer: Prediction: 135-140 litres Justification: Based on the consistent downward trend of approximately 1-2 litres decrease per year, consumption should continue to fall but may level off as conservation efforts reach their limits. Marking: 1 mark for reasonable prediction, 1 mark for justification based on trend analysis.

Question 20 [1 mark] State one advantage of using 6-figure grid references instead of 4-figure grid references.

Sample Answer: 6-figure grid references are more precise/accurate and can locate features to within 100m instead of 1km. Marking: Accept any valid advantage relating to precision, accuracy, or specific location identification.
