Answers

TuitionGoWhere Practice Paper — Geography Secondary 1

Answer Key — Version 4 of 5

Total Marks: 40

Section A: Map Skills (10 marks)

Q1. [1 mark]
Answer: The 4-figure grid reference of the fire station is 3158 (accept the correct reference based on the map provided).
Method: Read the easting (horizontal) first, then the northing (vertical). Use the lower-left corner of the grid square containing the fire station.
Marking note: Award 1 mark for the correct 4-figure reference. Accept no other format.

Q2. [1 mark]
Answer: The 6-figure grid reference of the bridge is 346573 (accept the correct reference based on the map provided).
Method: Read the easting (34), then estimate the tenths within the grid square (6 → 346). Read the northing (57), then estimate the tenths (3 → 573). Combine: 346573.
Marking note: Award 1 mark for the correct 6-figure reference. Common error: reversing easting and northing order.

Q3. [1 mark]
Answer: The school is to the northwest of the hospital.
Method: Locate the school (3359) and hospital (3656). The school is to the left (west) and above (north) of the hospital.
Marking note: Accept "NW" or "northwest". Do not accept "north" or "west" alone.

Q4. [2 marks]
Answer: The contour lines in grid square 3558 are closely spaced, indicating a steep slope. The contour values increase towards the east, suggesting the land rises in that direction, forming a hill or ridge.
Marking note:

1 mark for describing the contour spacing (closely spaced = steep).
1 mark for identifying the landform or direction of slope.
Accept "steep hill", "ridge", or "land rising to the east".

Q5. [3 marks]
Answer (sample — agree):
Evidence 1: The area around grid square 3255 is on flat land (contour lines are widely spaced), making construction easier.
Evidence 2: The area is near a road/transport link, providing good accessibility for residents.
I agree because the flat terrain reduces construction costs and the nearby road provides convenient transport.

Answer (sample — disagree):
Evidence 1: The area around grid square 3255 is near a river/floodplain, which may be at risk of flooding.
Evidence 2: The area may be designated as green space/agricultural land on the map, which is not suitable for housing.
I disagree because building on flood-prone land is risky and may not be permitted.

Marking note:

1 mark for each valid piece of map evidence (2 marks).
1 mark for a clear conclusion linked to the evidence.
Accept any reasonable answer supported by map evidence.

Section B: Graph & Data Interpretation (20 marks)

Marking note:

1 mark for correct working.
1 mark for correct answer (60%).

(b) [2 marks]
Answer:
15% of 200 km² = 0.15 × 200 = 30 km²
Marking note:

1 mark for correct method (15% × 200).

1 mark for correct answer (5°C).

(b) [2 marks]
Answer: From January to June, the temperature increased (from 26°C to 30°C) while rainfall decreased (from 200 mm to 40 mm). This shows an inverse relationship — as temperature rises, rainfall falls.
Marking note:

1 mark for describing the temperature trend (increasing).
1 mark for describing the rainfall trend (decreasing) or stating the inverse relationship.

(c) [2 marks]
Answer: City Y is likely in a tropical region because the temperatures are consistently high (25–30°C) throughout the year with a small annual range (only 5°C). Tropical regions have high temperatures year-round with little seasonal variation.
Marking note:

1 mark for referencing high temperatures.
1 mark for referencing small temperature range or linking to tropical climate characteristics.

Section C: Data Response & Application (10 marks)

Q11.
(a) [1 mark]
Answer: River D (WQI = 92 in September).

(b) [2 marks]
Answer:
Change = 65 − 78 = −13 (a decrease of 13).
Marking note:

1 mark for correct working (65 − 78).
1 mark for correct answer (−13 or decrease of 13).

(c) [1 mark]

Marking note: Award 1 mark for any plausible reason.

Q12.
(a) [2 marks]
Answer: Location X had the highest number of pedestrians in a single 10-minute period, with 52 pedestrians (9:20–9:30 a.m.).
Marking note:

1 mark for identifying Location X.

Total = 15 + 22 + 30 + 45 + 52 + 48 = 212 pedestrians
Marking note:

1 mark for correct working (showing addition).
1 mark for correct answer (212).

(c) [2 marks]
Answer: Both locations showed an increase in pedestrian traffic from 8:00 a.m. to around 9:20–9:30 a.m., after which numbers slightly decreased. Location X consistently had more pedestrians than Location Y at every time period, likely because it is near a shopping mall which attracts more people.
Marking note:

1 mark for describing the increasing-then-decreasing pattern at both locations.
1 mark for comparing the two locations (Location X higher than Y).

(d) [1 mark]
Answer: More people woke up and went out as the morning progressed / shops opened at the mall / park activities started later in the morning.
Marking note: Accept any reasonable reason.

Q13.
(a) [2 marks]
Answer: There is a negative (inverse) relationship between distance from the city centre and average house price. As the distance from the city centre increases, the average house price decreases.
Marking note:

1 mark for identifying the relationship as negative/inverse.
1 mark for describing the trend (as distance increases, price decreases).

(b) [2 marks]
Answer: At 5 km from the city centre, the average house price would be approximately ** $1.35 million**. This is estimated by interpolation: at 4 km the price is$ 1.5 million and at 6 km it is $1.2 million, so at 5 km (midway) the price is roughly halfway between, i.e.,$ 1.35 million.
Marking note:

1 mark for a reasonable estimate between $1.2 million and$ 1.5 million.
1 mark for explaining the interpolation method.
Accept answers between $1.2M and$ 1.5M with valid reasoning.

(c) [1 mark]
Answer: Areas farther from the city centre are less accessible / have fewer amenities / longer commuting times, so demand for housing is lower, leading to lower prices.
Marking note: Accept any reasonable reason.

Q14.
(a) [1 mark]
Answer: 35% + 5% = 40%

(b) [2 marks]
Answer:
20% of 400 million = 0.20 × 400 = 80 million gallons per day
Marking note:

1 mark for correct method (20% × 400).
1 mark for correct answer (80 million gallons).

(c) [2 marks]
Answer:
Advantage: Desalination provides a reliable / drought-resistant water source that does not depend on rainfall.
Disadvantage: Desalination is energy-intensive / expensive to operate / has high carbon emissions.
Marking note:

1 mark for a valid advantage.
1 mark for a valid disadvantage.

Q15.
(a) [3 marks]

Marking note:

1 mark for correct title and labeled axes.
1 mark for appropriate scale on the Y-axis.
1 mark for correctly drawn bars (all five bars at correct heights).
Deduct 1 mark if bars are not of equal width or if the scale is missing.

(b) [1 mark]
Answer: Others (5 items).
