Carbon Cycle & Greenhouse Effect (Deep Dive)

📋 What it is

Burning fossil fuels moves ancient buried carbon into the air fast, overloading the natural cycle.

🗣️ Coach says

For millions of years, carbon was locked underground as coal, oil and gas. Burning them releases that ancient carbon into the air as CO₂ far faster than the natural cycle can reabsorb it — so CO₂ builds up, thickening the heat-trapping blanket. It’s not new carbon; it’s old carbon released too fast.

🧠 Memory hook

Fossil fuels = ancient buried carbon. Burning them adds CO₂ faster than the cycle can absorb it.

😂 Giggle

Why did the wind turbine feel proud?
Because it was turning over a new leaf — with every revolution!

😲 Whoa!

The coal and oil we burn today came from plants and creatures that lived hundreds of millions of years ago — we’re releasing prehistoric sunlight, stored as carbon.

✅ Quick check: Why does burning fossil fuels raise CO₂ when carbon cycles naturally anyway?

Say your answer out loud first — then reveal.

🧪 Try it! (2 minutes)

Look at anything powered by gas/coal electricity and picture the ancient carbon it’s releasing.
