Total Marks: 40

Section A (1 mark each)

  1. height / elevation [1]
    Teaching: Contour lines connect equal heights; used to read terrain on topographic maps.
  2. a large drop / decline in tourists in 2020 [1]
    Teaching: Shorter bar = fewer arrivals; likely COVID-19 context but any valid drop reason accepted.
  3. time [1]
    Teaching: Line graphs of daily temp use x-axis as time (hours), y-axis as °C.
  4. residential [1]
    Teaching: 50% is largest slice; residential land use dominates.
  5. 50 000 cm (or 500 m) [1]
    Teaching: Scale 1:50 000 → 1 cm map = 50 000 cm real = 0.5 km.
  6. highest rainfall month [1]
    Teaching: In climate graph, rainfall bars height = monthly total; tallest = wettest.
  7. right (east) [1]
    Teaching: Grid coordinates (x,y): x right, y up.
  8. positive [1]
    Teaching: Points rise together → as one increases other increases = positive correlation.
  9. Town C [1]
    Teaching: 1500 is greatest density.
  10. larger population [1]
    Teaching: Proportional symbols size = value; bigger = more.

Section B

  1. [4] (a) Jun [1] (b) Range = 40 – 20 = 20 thousand [1] (c) School holidays / good weather in June [2] – any reasoned seasonal factor.
  2. [4] (a) Mar (29°C) [1] (b) Higher temp months (Feb, Mar) have lower rain; not strict but inverse-ish [2] (c) Mean = (200+150+100+180)/4 = 630/4 = 157.5 mm [1]
  3. [4] (a) D (MRT) [1] (b) A and B (west edge near river) [1] (c) Park provides green space, cooling, recreation near homes [2]

  6. [4] (a) Positive [1] (b) ~62 (midway 55–70) [1] (c) Small sample, correlation not cause [2]

Section C (3 marks each)

  1. [3] Mark descriptors: Map shows residential near factory (1). Graph of air quality would show higher pollutants nearby (1). Link: map+graph evidence supports health impact (1).
  2. [3] Pie plan: 4 slices with % (1). Bar graph adds exact comparison / ranking (1). State clarity (1).
  3. [3] Wet season limits outdoor (1), dry season good for tours (1), plan accordingly (1).
  4. [3] East = 3/9 = 33.3% [1]. Equity: East has more than others, uneven distribution [2].
