🌍 Global Warming

🌡️ What Is Global Warming?

Global warming means Earth's average temperature is increasing.

🔥 Burning Fuels

• Humans burn fuels like coal, petrol, and natural gas.

• Burning fuel is a chemical reaction.

• This reaction can produce carbon dioxide (CO₂).

🌬️ What Does CO₂ Do?

• CO₂ is a greenhouse gas.

• Earth gets heat from the Sun ☀️.

• Earth sends some heat back toward space.

• CO₂ can absorb some of this heat.

• CO₂ releases the heat in different directions.

• Some heat can go back toward Earth.

• This can make Earth's temperature increase. 🌡️

🧣 Easy Example

Greenhouse gases are like a blanket around Earth.

More greenhouse gases can act like a thicker blanket, keeping more heat in.

🧪 Is Global Warming a Chemical Reaction?

No.

Global warming itself is mainly a warming process, not one single chemical reaction.

However, chemical reactions like burning fuels can produce CO₂, which contributes to warming.

👨‍👩‍👧‍👦 Is It Good or Bad for Humans?

Human-caused global warming is bad for humans because a warmer Earth can create problems for people and the environment.

⭐ Main Idea

Burning fuels → CO₂ increases → more heat is trapped → Earth's temperature increases. 🌍🔥
