Glad you asked, Chloe! A greenhouse is just a little house made of glass, usually for plants to grow in. The glass lets the sun shine in but it doesn't let the heat go out, so the room gets nice and warm ­- great for growing plants! So greenhouses really are green because they have green things growing in them!

But, when we talk about the Greenhouse Effect, like my dad described here, we're not talking about an actual greenhouse. It means the Earth is LIKE a greenhouse, because it lets light in but doesn't let heat out. So the planet is getting warmer and warmer, like in a greenhouse, but we can't just open the door to cool off. We can't really cool off the earth, but we can do things to reduce our impact on making it warmer, like conserving electricity and biking instead of driving.
