Secondary 1 Geography Map Graph Data Skills Quiz

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

Total Marks: 40
Topic: Map, Graph & Data Skills

Section A: Map Reading

Q1. [1 mark]
Answer: 2962
Teaching note: A 4-figure grid reference gives the square. Read easting (across, 29) first, then northing (up, 62). The school is inside the square with bottom-left corner at 29 east, 62 north.
Common mistake: Reversing to 6229.

Q2. [1 mark]
Answer: 2862 (assuming temple shown there on map extract)
Teaching note: From the map, the temple south of school is in square 2862 (easting 28, northing 62). Always read easting then northing.
Marking: 1 mark for correct 4-figure reference.

Q3. [1 mark]
Answer: 285534 (or 285533–285535 acceptable)
Teaching note: 4-figure base = 2855. Reservoir is 3/10 across (easting +3) and 4/10 up (northing +4) → 285534. Six-figure splits each square into 10.
Common mistake: Giving only 4 figures.

Q4. [1 mark]
Answer: 10 m
Teaching note: Contour interval = difference between adjacent contours = 110 − 100 = 10 m.
Marking: 1 mark for 10 m.

Q5. [2 marks]
Answer: A hill; concentric contours increasing inward to 150 m summit.
Marking: 1 mark for landform type (hill), 1 mark for description (concentric, increasing height).
Teaching note: Closed loops with higher values inside show a hill. Steepness judged by spacing.

Q6. [1 mark]
Answer: 3162
Teaching note: Factory east of river (easting 31, northing 62). Read easting then northing.

Q7. [2 marks]
Answer: 4 km
Working:
Map scale 1:50 000 → 1 cm = 50 000 cm = 0.5 km.
Distance = 8 cm × 0.5 km/cm = 4 km.
Marking: 1 mark for correct conversion (0.5 km/cm), 1 mark for final answer.
Teaching note: Scale shows map distance to ground distance.

Section B: Graph Skills

Q8. [1 mark]
Answer: 280 mm
Teaching note: Read tallest bar = December 280 mm.

Q9. [2 marks]
Answer: Rainfall decreases from Jan to June (e.g., from about 240 mm to 120 mm).
Marking: 1 mark trend (decrease), 1 mark use of values.
Teaching note: Describe pattern with figures, not just “goes down”.

Q10. [1 mark]
Answer: Site A
Teaching note: Line for Site A is above Site B at all times.

Q11. [2 marks]
Answer: 4 °C (example: Site A 32 °C, Site B 28 °C)
Working: Difference = 32 − 28 = 4 °C.
Marking: 1 mark reading values, 1 mark subtraction.
(Values from graph: accept based on plotted lines.)

Q12. [1 mark]
Answer: 30%
Teaching note: Read labelled slice for Industry.

Q13. [2 marks]
Answer: Domestic use is largest (45%) because households need water daily for drinking, bathing, cooking.
Marking: 1 mark link to percentage, 1 mark reason.
Teaching note: Explain using daily needs.

Section C: Data Tables

Q14. [1 mark]
Answer: Mars
Teaching note: Mars has 2 moons, more than others.

Q15. [2 marks]
Answer: No clear relationship; Mercury/Venus close have 0, Earth further has 1, Mars furthest has 2.
Marking: 1 mark observation, 1 mark use of data.
Teaching note: Describe pattern across given data only.

Q16. [1 mark]
Answer: Site X
Teaching note: Higher dissolved oxygen, lower turbidity = healthier.

Q17. [2 marks]
Answer: Site X has DO 7.2 > 4.1 and turbidity 3 < 12.
Marking: 1 mark per evidence point.
Teaching note: Use table values to support.

Q18. [2 marks]
Answer: Decreased from 165 to 143 L/person/day.
Marking: 1 mark decrease, 1 mark values.

Q19. [3 marks]
Answer: Population rose 4.0→5.7m (+1.7m) while water use fell 165→143 L. So total use rose but per-person fell.
Marking: 1 mark pop trend, 1 mark water trend, 1 mark comparison.
Teaching note: Use both columns.

Q20. [3 marks]
Answer: 8 mm
Working: Total = 10+0+5+15+10 = 40 mm. Mean = 40 ÷ 5 = 8 mm.
Marking: 1 mark sum, 1 mark divide, 1 mark answer.
Teaching note: Mean = sum ÷ count.
