=__**Greenhouse Effect**__ =

Have you ever seen a greenhouse? Most greenhouses look like a small glass house. Greenhouses are used to grow plants, especially in the winter. Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, much like the inside of a car parked in sunlight, and keeps the plants warm enough to live in the winter.

Greenhouse gases in our atmosphere (the air around us) like carbon dioxide and methane are like a greenhouse. These gases trap heat. When heat from the sun comes to earth it tries to leave back to space but can't. These gases trap the heat. This is causing out Earth to heat up.

Think of it this way. Pretend you are under a blanket for a long time. You are going to get hot right? To cool yourself off you can take off the blanket. These greenhouse gases are like the blanket. They are causing us to become warm. The problem is that we can't take off the blanket.

Our planet needs greenhouse gases. Without them, we would freeze. But too many greenhouse gases is a bad thing.
