🎯 Common Question Types:
- Explain the greenhouse effect step by step (4–5 marks)
- Name greenhouse gases and their sources (2–3 marks)
- Distinguish natural from enhanced greenhouse effect (2 marks)
- Explain why the natural greenhouse effect is beneficial (1–2 marks)
- Describe human activities that increase greenhouse gas levels (2–3 marks)
📝 Key Command Words:
- Explain: Give the full mechanism (don't just say "gases trap heat")
- Name/List: CO₂, CH₄, H₂O vapour — learn exact chemical names
- Describe: State what happens step by step
- Distinguish: Explain the difference between natural and enhanced effect
⚠️ Common Mistakes to Avoid:
- Saying greenhouse effect is entirely bad — natural effect is essential for life
- Claiming N₂ and O₂ are greenhouse gases — they are not
- Confusing greenhouse effect with ozone depletion — different problems
- Saying water vapour is not a greenhouse gas — it is the most abundant one
- Not specifying "infrared" radiation in explanations
