TuitionGoWhere Practice Paper Answer Key — Geography Secondary 1 (Version 5)
Total Marks: 40
Level: Secondary 1
Topic: Map Graph Data Skills
Section A: Map Reading (16 marks)
1. [1 mark] 2765
- Teaching note: Grid reference reads EASTING (horizontal, left-to-right) first, then NORTHING (vertical, bottom-to-top). The temple is in square bounded by easting 27 and northing 65, so 2765.
- Common mistake: writing 6527 (reversed order).
2. [1 mark] 154705 (or 154704–154706 acceptable)
- Method: 4-figure square is 1547. School is near top (north) edge: about 7/10 up → third digit 7; across middle → 0/10 to 1/10 → 0 or 1. 154705 common.
- Marking: 1 mark for correct 6-figure format in square 1547.
3. [1 mark] 10 m
- From map in Q2 (standard 1:50,000 extract), adjacent contours labelled 10 m apart.
- Note: contour interval is difference between neighbouring contour lines, not map scale.
4. [2 marks] 3723
- Mark breakdown: 1 mark easting 37, 1 mark northing 23. Forest east of river in square 3723.
- Trap: picking west-side square 3525.
5. [3 marks]
- A hill (1 mark).
- Concentric contour lines with values increasing towards centre (1 mark).
- Highest contour 40 m, steep/close spacing optional (1 mark).
- Teaching: closed loops = hill or depression; increasing in = hill.
6. [1 mark] 4455
- Bridge symbol in square 4455.
7. [3 marks]
- Step 1: Grid difference: easting 44–15 = 29; northing 55–47 = 8 (in grid units of 1 km at 1:50,000 since 1 square = 1 km).
- Step 2: Distance = √(29² + 8²) = √(841+64)=√905 ≈ 30.1 grid units.
- Step 3: At 1:50,000, 1 grid square = 1 km → ≈ 30.1 km.
- Marks: 1 for Δeasting/Δnorthing, 1 for Pythagoras, 1 for final ~30 km.
- Common error: forgetting square root or using cm.
8. [3 marks]
- Reservoir (1546) is SOUTH of school (1547) because northing 46 < 47 (1 mark).
- Slightly WEST if same easting 15 (1 mark).
- Therefore south (or south-west) (1 mark).
- Teaching: lower northing = south.
Section B: Graph & Table Skills (12 marks)
9. [1 mark] Jupiter (95 moons)
- From table, scan "Number of Moons" column max = 95.
10. [3 marks]
- Generally, planets farther from Sun have more moons (1 mark).
- Mercury/Venus (close) have 0; Jupiter (far) has 95 (1 mark with evidence).
- Exception not needed but pattern stated (1 mark).
- Teaching: describe pattern not just points.
11. [1 mark] November (280 mm)
12. [2 marks]
- Sum values: e.g. Jan 120+Feb 40+Mar 90+Apr 130+May 160+Jun 180+Jul 190+Aug 170+Sep 140+Oct 200+Nov 280+Dec 210 = 1910 mm.
- 1 mark for correct addition, 1 mark for unit (mm).
- (Exact total depends on fig; use stated bars.)
13. [3 marks]
- Country A decreased from 160 to 140 L/person/day (1 mark).
- Country B increased from 120 to 130 L (1 mark).
- Opposite trends: A conservation, B rise (1 mark).
- Evidence from Figure C required.
14. [2 marks]
- Site 1 (forest stream) healthier (1 mark).
- Reason: higher dissolved oxygen 8.0 > 4.5 and lower turbidity 2 < 15 (1 mark, data cited).
Section C: Integrated (12 marks)
15. [2 marks] Any two from: river, grid lines, easting/northing labels, open land (1 each). Must be in 2765.
16. [2 marks]
- Hill rises to 40 m above surroundings (1 mark).
- Clear view over lower land (1 mark).
- Teaching: elevation gives vantage.
17. [2 marks]
- Valley 27°C warmer than hilltop 24°C (1 mark).
- Difference 3°C, likely cold air sinks to valley or heat retention (1 mark).
- (Syllabus: simple observation, no deep meteorology needed.)
18. [1 mark] Domestic (45%)
19. [2 marks]
- Industry 30% of 360° = 0.30 × 360 = 108° (1 mark calc, 1 mark unit).
- Teaching: pie full circle 360°.
20. [3 marks]
- Statement incorrect (1 mark).
- Mercury/Venus close but 0 moons; Jupiter far with 95 (1 mark evidence).
- Therefore distance not cause of moon count (1 mark).
- Teaching: use data to reject claim.
