Let's solve the
Greenhouse Effect Worksheet (Exercise 1) step by step. This is a science activity designed to help students understand how fossil fuels, greenhouse gases, and the greenhouse effect contribute to global warming.

1. Fossil fuels contain carbon from plants and animals that died millions of years ago.
Question: What happens when we burn fossil fuels?
✔ Answer:
When we burn fossil fuels (like coal, oil, and natural gas), the carbon stored in them reacts with oxygen in the air to produce
carbon dioxide (CO₂) and other gases. This releases large amounts of CO₂ into the atmosphere, which contributes to the greenhouse effect.
> 💡 *Example:*
> Burning coal → Carbon + Oxygen → Carbon Dioxide (CO₂) + Heat

2. A greenhouse gas traps heat in the Earth’s atmosphere.
Question: How does a greenhouse gas trap heat in the Earth’s atmosphere?
✔ Answer:
Greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and water vapor absorb infrared radiation (heat) from the Sun that has been reflected off the Earth's surface. Instead of letting this heat escape into space, these gases
trap it, causing the Earth to warm up—just like the glass in a greenhouse keeps warmth inside.
> 🌍 *Visual Explanation:*
> Sunlight enters the atmosphere → Earth absorbs it → Earth emits heat (infrared radiation) → Greenhouse gases absorb and re-radiate the heat back toward Earth → Earth warms.

3. As more and more carbon dioxide goes into the atmosphere, we begin to trap more heat and the Earth gets warmer and warmer.
Question: What happens when the Earth gets warmer?
✔ Answer:
When the Earth gets warmer due to increased greenhouse gases:
- Ice caps and glaciers melt, leading to
rising sea levels.
- Weather patterns change, causing more extreme weather events (e.g., hurricanes, droughts, floods).
- Ecosystems are disrupted — some species may not survive.
- Oceans become more acidic as they absorb excess CO₂.
- Human health and agriculture can be affected.
> 🌪️ *Summary:*
> Global warming leads to
climate change, which impacts nature, wildlife, and human societies worldwide.

✔ Final Answers Summary:
| Question | Answer |
|--------|--------|
| What happens when we burn fossil fuels? | We release carbon dioxide (CO₂) and other greenhouse gases into the atmosphere. |
| How does a greenhouse gas trap heat in the Earth’s atmosphere? | It absorbs infrared radiation (heat) from the Earth and re-radiates it back, trapping warmth. |
| What happens when the Earth gets warmer? | Climate change occurs: melting ice, rising sea levels, extreme weather, ecosystem disruption, etc. |

📝 Tips for Students:
- Use simple language when explaining to your partner.
- Refer to the diagrams: The yellow arrows represent sunlight; red arrows show trapped heat.
- Take turns asking and answering so both students learn.
