What Causes the ‘Greenhouse Effect’?

The greenhouse effect is like having a blanket around Earth that keeps it warm.

Imagine you're wearing a cozy sweater on a chilly day, it traps your body heat and keeps you from getting too cold. The greenhouse effect works in a similar way, but instead of a sweater, we have special gases in the air called greenhouse gases, like carbon dioxide and methane.

When sunlight hits Earth, some of it goes through the atmosphere and warms the ground. Then, Earth sends that heat back into the sky, kind of like how your body gives off warmth after you're wrapped up in a blanket.

But here’s the fun part: the greenhouse gases catch some of that heat before it can escape into space. They’re like tiny heat-trapping superheroes in the sky, holding on to the warmth and sending some of it back down to Earth, just like your sweater keeps you warm.

This is why Earth stays at a comfortable temperature instead of being super cold all the time. Without the greenhouse effect, our planet would be more like a freezer than a cozy room!
