Secondary 3 Geography Quiz - Physical Geography: Answer Key

Total Marks: 40
Topic: Physical Geography (Climate & Tectonics)
Note: Syllabus-first content from inferred templates; not exam-derived.

Section A: Multiple-Choice (1 mark each)

B [1]
Teaching note: The greenhouse effect is when gases like CO₂ trap infrared heat. A is wrong (heat escapes partly). C and D are unrelated.
B [1]
Teaching note: Internal heat from radioactive decay and leftover formation heat drives mantle convection, not solar (A) or tides (C).
C [1]
Teaching note: Constructive = plates diverge, magma rises, new crust. A is destructive, B is conservative, D is subduction.
C [1]
Teaching note: Tropical zone at Equator gets direct sun; polar (A) cold, temperate (B) seasonal, arid (D) dry not latitude-based.
B [1]
Teaching note: Richter scale measures energy released. Depth (A) is separate; affected people (C) and cost (D) are impact not magnitude.

Section B: Short Structured (2 marks each)

[2] Any two natural causes:
- Volcanic eruptions (release aerosols)
- Solar output variation
- Orbital changes (Milankovitch)
  Marking: 1 mark each, accept any two valid (e.g. ocean currents shift). Common mistake: listing human causes.
[2] A plate boundary is the margin where two tectonic plates meet and interact.
Marking: 1 for “margin between plates” + 1 for “interact/move”.
[2] (a) Constructive (divergent) (b) Destructive (convergent) OR Conservative (transform).
Marking: 1 each, any two correct types.
[2] Evidence: (a) matching coastlines (e.g. S. America/Africa) (b) same fossils across oceans (Mesosaurus).
Marking: 1 each; accept rock layers, glacier scars.
[2] Weather is short-term atmospheric condition; climate is average weather over 30+ years.
Marking: 1 for difference in time, 1 for definition clarity.

Section C: Data & Extended (11–20)

(a) [2] Temperature stays high (25–29°C) all year with small range.
Marking: 1 constant high, 1 small annual range.
(b) [2] Tropical rainforest climate; reason: high rain every month (>150 mm) and steady heat.
Marking: 1 type, 1 reason from graph.
[3] Greenhouse gases absorb outgoing infrared, re-radiate to surface, keeping avg ~15°C vs -18°C.
Marking: 1 trap heat, 1 warms surface, 1 supports life (liquid water).
Note: Explain simply: without it Earth would freeze.
[3] Oceanic plate sinks, melts, magma rises through continental crust, erupts as volcano.
Marking: 1 subduction, 1 melting/magma, 1 volcano build. Use diagram labels.
[3] (a) sea level rise (b) glacier melt (c) coral bleaching / habitat loss.
Marking: 1 each, any valid environmental effect.
[4] Rainfall: rainforest >2000 mm/yr, desert <250 mm. Temperature range: rainforest small daily range, desert large day-night range.
Marking: 2 for rainfall contrast, 2 for temp range contrast.
[3] Wrong because earthquakes also at constructive (rift) and conservative (fault slip).
Marking: 1 statement false, 2 for other boundary examples.
(a) [1] Convergent.
(b) [2] Plates slide past, friction builds, sudden release = quake.
Marking: 1 friction, 1 release mechanism.
[3] Sustainable dev = meet present needs without harming future. Climate action reduces emissions for long-term safety.
Marking: 1 def, 2 link to climate.
(a) [1] Zone of many volcanoes/quakes around Pacific.
(b) [2] Plates converge there, cause quakes.
Marking: 1 ring def, 1–2 plate reason.
[4] Agree: (1) burning fossil fuels raised CO₂ (2) deforestation cut sinks.
Marking: 2 points × 2 marks, each with explanation. </stage5_quiz_answers_md>
