- Marking note: Award 1 mark for the correct 4-figure grid reference. Do not accept reversed order (e.g., 5430).
(b) 1 mark
- Answer: 315547 (easting: 31 + 5 tenths = 315; northing: 54 + 7 tenths = 547)
- Marking note: Award 1 mark for the correct 6-figure grid reference. Accept answers where the estimation is reasonable (e.g., 314546 to 316548).
Question 2 (3 marks)
(a) 1 mark
- Answer: North-east (or NE)
- Marking note: Accept "NE" or "north-east". Do not accept vague answers like "up and right".
(b) 2 marks
- Answer: The land is hilly / mountainous. The contour lines are close together, indicating a steep slope. The contour values increase towards the centre of the grid square, suggesting a hill or ridge.
- Marking scheme:
- 1 mark for identifying the area as hilly/steep/high land.
- 1 mark for using evidence from contour lines (e.g., close together, increasing values).
Question 3 (2 marks)

- 180 + 140 + 200 + 250 + 280 + 260 + 220 + 230 + 270 + 310 + 340 + 290
- = 2,970 mm
- Marking scheme:
- 1 mark for correct addition process (at least 8 values correctly added).
- 1 mark for correct final answer (2,970 mm).
- Common error: Arithmetic mistakes. If the method is correct but the final answer has a minor addition error, award 1 mark.
Question 10 (2 marks)
(a) 1 mark
- Answer: Rainfall increases from February (140 mm) to May (280 mm). There is a steady upward trend / rainfall more than doubles.
- Marking note: Award 1 mark for describing an increasing trend. Do not accept "it goes up" without reference to data.
(b) 1 mark
- Answer (any one):
- The area may experience a monsoon season / wet season during the second half of the year.
- Convectional rainfall is more frequent due to higher temperatures and humidity.

- Marking note: Accept any reasonable geographical explanation.
Question 11 (3 marks)
(a) 1 mark
- Answer: 29°C (recorded in April and May)
(b) 2 marks
- Working:
- Highest temperature = 29°C
- Lowest temperature = 26°C
- Range = 29 − 26 = 3°C
- Marking scheme:
- 1 mark for identifying the highest and lowest values.
- 1 mark for correct answer (3°C).
Question 12 (3 marks)
(a) 1 mark
- Answer: August (rainfall = 230 mm, temperature = 27°C) OR December (rainfall = 290 mm, temperature = 26°C)
- Marking note: Award 1 mark for any month where rainfall is among the highest AND temperature is below 28°C. Accept August or December.
(b) 2 marks
- Answer: Rainfall is not solely determined by temperature. Other factors such as monsoon winds, the movement of the ITCZ, ocean currents, and relief/orographic effects influence rainfall patterns. High temperatures may cause evaporation, but rainfall depends on moisture availability and atmospheric conditions such as the presence of rain-bearing winds.
- Marking scheme:
- 1 mark for stating that other factors besides temperature affect rainfall.
- 1 mark for elaborating with at least one specific factor.
Question 13 (4 marks)
(a) 3 marks

- 1 mark for correctly drawn bars (all four bars at approximately correct heights: A = 45, B = 62, C = 38, D = 55).
- 1 mark for labelled axes (x-axis: Town; y-axis: Population (thousands)) and a suitable title (e.g., "Population of Four Towns in 2023").
- Common errors: Forgetting the title, unlabelled axes, incorrect scale starting from a non-zero value.
(b) 1 mark
- Answer: Town D (55,000)
- Working: Arrange in order: 38 (C), 45 (A), 55 (D), 62 (B). With an even number of values, the median is the average of the two middle values: (45 + 55) / 2 = 50. The town closest to the median is Town D (55,000). Accept Town A or Town D if the student explains their reasoning.
- Marking note: If the student calculates the median as 50 and identifies either Town A or Town D as closest, award the mark.

Question 20 (5 marks)
(a) 1 mark
- Working: 120 − 40 = 80 metres

- Marking scheme:
- 1 mark for correctly describing each slope (gentle west, steep east).
- 1 mark for using contour line spacing as evidence.
(c) 2 marks
- Answer: The western (gentle) slope is more suitable for farming because:
- It is easier to plough and work on flat/gentle land.
- There is less risk of soil erosion compared to the steep eastern slope.
- Water and nutrients are retained better on gentle slopes.
- Marking scheme:
