Secondary 2 Geography Quiz - Physical Geography (Answer Key)

Total Marks: 40

---

Section A: Map and Data Skills [10 marks]

1. Four-figure grid reference of lighthouse [1 mark]

• Answer: Accept any reasonable four-figure grid reference (e.g., 2435, 1567)
• Marking note: Award 1 mark for correct format (four digits with easting first, then northing)

2. Rainfall pattern description [2 marks] Sample answer: The rainfall shows a distinct wet and dry season pattern. Rainfall is highest during June to September, reaching a peak of 280mm in July. The dry season occurs from December to March, with lowest rainfall of 15mm in February.

Marking scheme:

• 1 mark: Identification of wet/dry seasons or seasonal pattern
• 1 mark: Specific statistics cited (at least 2 values with months)

3. River feature and formation [2 marks] Sample answer: Feature: Meanders/river bends Explanation: Formed by lateral erosion on the outer bank and deposition on the inner bank due to differences in water velocity

Marking scheme:

• 1 mark: Feature correctly identified
• 1 mark: Correct explanation of formation process

4. Drainage density calculation [2 marks] Working: Drainage density = Total river length ÷ Catchment area = 45 km ÷ 15 km² = 3 km/km²

Marking scheme:

• 1 mark: Correct working shown
• 1 mark: Correct answer with units

5. Landform identification and slope direction [3 marks] Answer: Landform: Hill/Mountain (accept appropriate landform based on contour pattern) Direction: Accept appropriate compass direction based on contour spacing

Marking scheme:

• 1 mark: Correct landform identified
• 2 marks: Correct direction of steepest slope

---

Section B: Water Systems [10 marks]

6. Water budget definition [2 marks] Answer: Water budget is the balance between water inputs (precipitation) and outputs (evapotranspiration and runoff) in a drainage basin or catchment area over a specific time period.

Marking scheme:

• 1 mark: Reference to balance/relationship between inputs and outputs
• 1 mark: Mention of specific inputs (precipitation) and outputs (evapotranspiration/runoff)

7. Process at point Y [1 mark] Answer: Evaporation Accept: Evapotranspiration

8. Freshwater distribution description [3 marks] Sample answer: Freshwater represents only 2.5% of total global water, with the majority (97.5%) being saltwater in oceans. Of the freshwater, 68.7% is stored as ice in glaciers and ice caps. Groundwater accounts for 30.1% of freshwater stores, while surface water represents only 1.2%.

9. Water pollution from human activities [4 marks] Sample answer: Activity: Agricultural farming using fertilizers Process: Excess fertilizers containing nitrogen and phosphorus are washed off the land as surface runoff into nearby rivers during rainfall.
