What Causes the ‘Greenhouse Effect’ and How Does It Affect Earth?

Imagine Earth is like a house. The sun sends light and heat in, and the Earth keeps some of that heat inside so we can stay warm. But sometimes too much heat stays trapped, just like when you close all the windows on a hot day. That’s the greenhouse effect!

What Is the Greenhouse Effect?

Some gases in the air, like carbon dioxide, act like curtains that let sunlight in but keep the warm air inside. They're called greenhouse gases.

Why It Matters

When there are more of these gases, they trap even more heat. That makes Earth get warmer, and that’s why we see changes in our weather and environment.

Examples

  1. Imagine you're wearing a blanket on a cold night, that's like the greenhouse effect keeping Earth warm.
  2. When you close your windows during winter, it's like the greenhouse gases trapping heat inside the atmosphere.
  3. A car parked in the sun gets really hot inside because sunlight passes through the glass but the heat can't escape, that’s similar to what happens with greenhouse gases.
