What is greenhouse effect simple definition?
The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
What’s the definition of greenhouse gas?
A greenhouse gas is a gas that absorbs infrared radiation (IR) and radiates heat in all directions. Greenhouse gases in the earth’s atmosphere absorb IR from the sun and release it. Some of the heat released reaches the earth, along with heat from the sun that has penetrated the atmosphere.
