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.
It releases long-buried carbon into the air FASTER than nature can reabsorb it, so CO₂ accumulates.
The rate of release outpaces natural uptake.
