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

Total Marks: 40

Section A: Map Skills (15 marks)

1. 4-figure grid reference of the school

Answer: 3472
Marks: [1]
Explanation:

  • 4-figure grid references are read as eastings first (horizontal), then northings (vertical).
  • The school symbol is in the grid square where easting line 34 meets northing line 72.
  • The reference is the lower-left corner of that square: 3472.
    Common mistake: Reversing the order (e.g., 7234) or using the wrong corner.

2. 6-figure grid reference of spot height 142

Answer: 353734
Marks: [1]
Explanation:

  • 6-figure references divide each 1 km grid square into 10 tenths (100 m each).
  • Spot height is at 3/10 easting (35.3) and 4/10 northing (73.4) within square 3573.
  • Easting: 35 + 3 = 353
  • Northing: 73 + 4 = 734
  • Combined: 353734
    Mark breakdown: Correct easting (1), correct northing (1) — but total 1 mark for full correct reference.

3. Map symbol at 3671

Answer: Place of worship / Church / Temple (cross on a square)
Marks: [1]
Explanation:

  • At grid reference 3671, the symbol shown is a cross on a square, which represents a place of worship (church, temple, mosque, etc.) on topographic maps.
  • The minor road is a linear feature, not a point symbol.

4. 4-figure grid reference of the police station (south-west of post office)

Answer: 3273
Marks: [1]
Explanation:

  • Post office (PO) is at 3374.
  • South-west means lower easting (west) and lower northing (south).
  • Moving one square west: easting 33 → 32.
  • Moving one square south: northing 74 → 73.
  • Police station (PS) is at 3273.
    Key skill: Using cardinal directions with grid references.

5. Straight-line distance between school (3472) and place of worship (3671)

Answer: 2.2 km (accept 2.1–2.3 km)
Marks: [2]
Working:

  • School at approx. centre of 3472 → coordinates (34.5, 72.5)
  • Place of worship at approx. centre of 3671 → coordinates (36.5, 71.5)
  • Difference in eastings: 2.0 km; difference in northings: 1.0 km
  • Straight-line distance = √(2.0² + 1.0²) = √5 ≈ 2.24 km
  • Using map scale 1:25,000, measure with ruler and convert.
    Mark breakdown: Correct method (1), correct answer with units (1).

6. Landform in grid square 3573 from contour pattern

Answer: A conical hill (or isolated hill / knoll) with a summit at 142 m.
Marks: [2]
Explanation:

  • Contours form closed concentric loops with values increasing towards the centre (100 → 110 → 120 → 130 → 140 m).
  • Spot height 142 m at the centre confirms the highest point.
  • Even spacing of contours indicates uniform slope.
    Mark breakdown: Identifies hill (1), describes contour evidence (closed loops, increasing inward) (1).

7. Gradient between spot height 142 and 100 m contour (west)

Answer: 1 : 7.1 (accept 1 : 7 or 1 : 7.14)
Marks: [2]
Working:

  • Vertical difference (rise) = 142 m – 100 m = 42 m
  • Horizontal distance (run) = 300 m (given: from easting 35.3 to 35.0 = 0.3 km = 300 m)
  • Gradient = Vertical : Horizontal = 42 : 300
  • Simplify: divide both by 42 → 1 : (300 ÷ 42) = 1 : 7.14
    Mark breakdown: Correct vertical/horizontal values (1), correct ratio calculation and format (1).

8. Why northern slope is steeper than southern slope

Answer:
The contour lines are closer together on the northern slope than on the southern slope.
Marks: [2]
Explanation:

  • Closer contour lines = steeper slope; wider spacing = gentler slope.
  • On the map, the 10 m interval contours are packed tightly on the north side of the hill, while they are more spread out on the south side.
  • This indicates a steeper gradient on the northern face.
    Mark breakdown: States contour spacing difference (1), links to steepness (1).

9. Compass direction from spot height 142 to school

Answer: NW (North-West)
Marks: [1]
Explanation:

  • Spot height 142 is in grid square 3573 (approx. 35.3, 73.4).
  • School is in grid square 3472 (approx. 34.5, 72.5).
  • The school is west (lower easting) and south (lower northing) of the spot height.
  • But wait: 73.4 → 72.5 is south; 35.3 → 34.5 is west → South-West (SW).
    Correction: The school is at 3472 (northing 72), spot height at 73.4 → school is south. Easting 34.5 vs 35.3 → school is west. So direction is SW.
    Correct Answer: SW
    (Note: In the question, "north-eastern part of the map" for school at 3472 — if map northings increase upward, 72 is south of 73. So SW is correct.)

10. Area of built-up area in grid square 3474

Answer: 0.6 km² (accept 0.55–0.65 km²)
Marks: [2]
Working:

  • Each grid square = 1 km × 1 km = 1 km².
  • Built-up shading covers ~60% of the square.
  • Area = 60% × 1 km² = 0.6 km².
    Mark breakdown: Correct total grid square area (1), correct estimation and calculation (1).

Section B: Graph and Data Interpretation (15 marks)

11. Highest and lowest temperature months

Answer:
Highest: May (or Jun/Jul/Aug — all 28°C)
Lowest: Jan and Dec (both 26°C)
Marks: [2]
Explanation:

  • Temperature line peaks at 28°C from May to August (4 months tied). Any one is acceptable.
  • Lowest is 26°C in January and December.
    Mark breakdown: Correct highest month (1), correct lowest month (1).

12. Annual temperature range

Answer: 2 °C
Marks: [1]
Working:

  • Annual range = Highest monthly temp – Lowest monthly temp
  • = 28 °C – 26 °C = 2 °C
    Note: This small range is typical of tropical climates near the equator.

13. Wettest month and rainfall

Answer:
Month: May (or Dec — both 300 mm)
Rainfall: 300 mm
Marks: [1]
Explanation:

  • Highest rainfall bar is 300 mm, occurring in May and December. Either month accepted.

14. Rainfall pattern description with data

Answer:
The rainfall is high throughout the year (all months > 150 mm), with two peaks in May (300 mm) and December (300 mm), and a drier period from June to September (lowest in July at 150 mm). There is no distinct dry month.
Marks: [3]
Mark breakdown:

  • Identifies high year-round rainfall (1)
  • Identifies twin peaks / bimodal pattern with months and data (1)
  • Notes drier mid-year period with data (1)
    Key concept: Tropical equatorial climate with double rainfall maxima (inter-monsoon periods).

15. Two characteristics of population pyramid (Country Y)

Answer:

  1. Broad base — high percentage of young population (0–14 years), indicating high birth rate.
  2. Narrow top / tapering shape — very small percentage of elderly (65+), indicating low life expectancy and high death rate.
    Marks: [2]
    Explanation:
  • This is an expansive (youthful) population pyramid, typical of less developed / developing countries.
  • Other valid points: high dependency ratio, rapid population growth, short life expectancy.

16. Social implication for Country Y in 20 years

Answer:
A large youth cohort entering the workforce will create pressure for job creation, education, and housing. If the economy cannot absorb them, it may lead to unemployment and social unrest.
Marks: [2]
Explanation:

  • The broad base (0–14) will become the working-age population (20–34) in 20 years.
  • This is a "youth bulge" — a demographic challenge requiring investment in human capital.
    Mark breakdown: Identifies implication (1), explains link to pyramid structure (1).

17. River failing most parameters

Answer:
River: River B
Number of failed parameters: 5 (all five parameters fail)
Marks: [2]
Checking each parameter for River B:

  • Dissolved Oxygen: 4.1 mg/L < 5.0 → Fail
  • BOD: 8.3 mg/L > 3.0 → Fail
  • Nitrate: 12.5 mg/L > 10.0 → Fail
  • pH: 6.2 < 6.5 → Fail
  • Total Coliform: 2400 > 100 → Fail
    River A: Passes all. River C: Passes all (Nitrate 4.8 < 10, Coliform 180 > 100? Wait — 180 > 100 → Fail for coliform. But River B fails 5, River C fails 1. So River B fails most.)
    Correction: River C coliform 180 > 100 → fails 1 parameter. River B fails 5. So River B is correct.

18. Percentage by which River B's BOD exceeds safe limit

Answer: 177% (accept 176.7%)
Marks: [2]
Working:

  • Safe limit = 3.0 mg/L
  • River B BOD = 8.3 mg/L
  • Excess = 8.3 – 3.0 = 5.3 mg/L
  • Percentage excess = (Excess ÷ Safe limit) × 100% = (5.3 ÷ 3.0) × 100% = 176.67% ≈ 177%
    Mark breakdown: Correct excess calculation (1), correct percentage formula and answer (1).

Section C: Geographical Skills Application (10 marks)

19. Traffic count data

(a) Percentage of motorcycles
Answer: 34%
Marks: [2]
Working:

  • Total vehicles = 120 + 85 + 15 + 20 + 10 = 250
  • Motorcycles = 85
  • Percentage = (85 ÷ 250) × 100% = 34%

(b) Pie chart angle for Cars
Answer: 172.8° (accept 173°)
Marks: [2]
Working:

  • Cars = 120 out of 250 total
  • Angle = (120 ÷ 250) × 360° = 0.48 × 360° = 172.8°
    Mark breakdown: Correct total (implied), correct fraction (1), correct angle calculation (1).

20. Noise level data

(a) Mean noise level at 8:00 am
Answer: 67.4 dB
Marks: [1]
Working:

  • Sum = 72 + 68 + 70 + 65 + 62 = 337
  • Mean = 337 ÷ 5 = 67.4 dB

(b) Comparison and reason
Comparison: Noise levels are higher at 6:00 pm than at 8:00 am at all 5 locations (by 3–7 dB).
Reason: Evening peak hour traffic — more vehicles returning from work/school, increased commercial activity, and possibly atmospheric conditions (temperature inversion) trapping sound.
Marks: [2]
Mark breakdown: Correct comparison with data reference (1), valid geographical reason (1).
