How do greenhouse gases trap heat in Earth's atmosphere?

Earth’s atmosphere is like a cozy blanket that keeps us warm, and greenhouse gases are the threads that help keep it snug.

Imagine you're wearing a light jacket on a chilly day, and then someone throws a soft sweater over it. That’s what greenhouse gases do: they let sunlight pass through the sky like a clear window, but when the sun goes down, they catch some of the heat your Earth has absorbed, like a warm sweater catching the warmth from your body.

Think of greenhouse gases as tiny bubbles in the air. When sunlight comes to Earth, it warms up the ground and everything on it. Then that heat tries to escape back into space, but those little bubbles catch some of it, like a trampoline catching you when you jump.

Instead of all the warmth escaping, it bounces around inside the atmosphere, just like how your room feels warmer with curtains than without them.

So every time there are more of these tiny bubbles, Earth keeps getting a little cozier, and that's why it gets warmer over time. Earth’s atmosphere is like a cozy blanket that keeps us warm, and greenhouse gases are the threads that help keep it snug.
