Did you know Earth wears an invisible "blanket" made of air?
It keeps our planet warm and cosy — just right for plants, animals, and you! Let's find out how it works. 👀
🔆 The Sun warms the Earth.
🌫️ Special gases in the air trap some of that warmth.
😊 That keeps Earth comfy — not too hot, not too cold.

A greenhouse is a glass house where gardeners grow plants. Sunlight shines in through the glass and warms the air inside — but the glass stops the warmth from escaping, so it stays toasty.
Earth's gases work just like that glass! That's why we call it the greenhouse effect. 🌍
Quick check — what does the glass of a greenhouse do?
A thin blanket of gases keeps Earth comfy. But if we add too many greenhouse gases, the blanket gets thick and Earth gets too warm. Slide to add gases and watch! 👇
Just right 🌍
Try sliding to the very right, then back to a comfy spot.
Some things add more greenhouse gases; other things add less. Drag each card into the right basket. (On a tablet, press and drag!)
