What is the greenhouse effect?
The greenhouse effect is a process that helps keep the Earth warm enough for people, plants and animals to live on. Think of the Earth like a giant greenhouse. Imagine the Earth’s atmosphere like the glass of a greenhouse. Both the gases of our atmosphere and the glass of a greenhouse trap the sun’s heat energy inside keeping the temperature balanced; not too hot or too cold. This is why some of the gases in our atmosphere are called “greenhouse gases”.
