TuitionGoWhere Practice Paper - Geography Secondary 1 (Version 5) Answer Key

Total Marks: 60

Section A: Map Skills

Q1. 1221 [1]
Teaching note: Read easting (horizontal, left to right) first = 12, then northing (vertical, bottom to top) = 21. Grid reference is the lower-left corner of the square containing the School.

Q2. 132 224 (acceptable range 132 223–132 225) [1]
Teaching note: 4-figure = 1322. Subdivide square into 10×10. Hospital is ~3/10 across (easting 132) and ~4/10 up (northing 224).

Q3. 10 m [1]
Teaching note: Contour interval = difference between adjacent labelled contours = 110 − 100 = 10 m.

Q4. 3142 [1]
Teaching note: River mouth is at coast inside square with lower-left corner easting 31, northing 42.

Q5. 212 276 (acceptable 212 275–212 277) [1]
Teaching note: Base 2127; hilltop at 5/10 across → 212, 6/10 up → 276.

Q6. [2]
Method:
Scale 1:50 000 means 1 cm on map = 50 000 cm actual.
Map distance = 8 cm.
Actual = 8 × 50 000 = 400 000 cm.
Convert to km: 400 000 cm ÷ 100 000 = 4 km.
Answer: 4 km [2 marks: 1 for correct multiplication, 1 for km conversion]

Q7. [2]
Any two of: buildings, roads, railway lines, schools, hospitals, boundaries. [1 each]
Teaching note: Human features are made by people, shown by point, line, or area symbols.

Q8. [2]
Explanation: Student reversed easting and northing (wrote 23 14 instead of 14 23) OR misread the grid lines. [2 for identifying reversal or misread with correct order]
Teaching note: Always easting then northing.

Section B: Graph & Data Interpretation

Q9. Highest: City D (3000 mm); Lowest: City C (800 mm) [1+1]
Teaching note: Scan table column for max and min values.

Q10. [2]
Difference = 2400 − 800 = 1600 mm [2]
Method: Subtract lowest from highest among named cities B and C.

Q11. [3]
Mark descriptors:

• States temperatures rise from Jan to Mar (28→31) [1]
• States fall from Mar to Jun (31→26) [1]
• Uses comparative language / overall pattern (peak in Mar, then decline) [1]
  Teaching note: Describe trend using data points, not just list.

Q12. [3]

• Consumption decreased from 160 to 130 L/person/day [1]
• Steady fall each year [1]
• Total drop of 30 L [1]
  Teaching note: Reference graph values; show pattern not just endpoints.

Q13. [3]
Healthier: Site X [1]
Reason: Higher dissolved oxygen (8.2 > 4.1) supports aquatic life; lower turbidity (2 < 9) means clearer water [2]
Teaching note: Good water = high DO, low turbidity.

Q14. 30% + 20% = 50% [2]
Teaching note: Add housing and industry slices from pie chart.

Section C: Applied Data Skills

Q15. [2]
Actual = 5 cm × 25 000 = 125 000 cm = 1.25 km [2: 1 for calc, 1 for conversion]

Q16. Greatest: Q (2.5 m); Least: R (0.8 m) [1+1]

Q17. [3]
Slope: Steep [1]
Reason: Contours are close together, meaning 30 m rise over short distance [2]
Teaching note: Close contours = steep gradient.

Q18. [3]
Trend: Population increased from 15k to 38k over 20 years [1], rapid growth especially 2005–2015 [1]
Reason: e.g., migration, new housing estates [1]
Teaching note: Use graph values; reason should link to human geography.

Q19. [2]
Error: Used 6 figures on a map that only shows 4-figure grids / invented extra digits [2]

Q20. [4]
Pattern: Recycling rate increased steadily by 5% each year [2: describes trend with data]
Total increase = 35% − 20% = 15% [2: correct subtraction]
Teaching note: Show both description and calculation for full marks.
