Category: Atmosphere. The atmosphere, a thin shell of gases surrounding the Earth, is a very effective protective shield that reflects and absorbs harmful radiation and objects like meteorites.
The ability of certain trace gases to be relatively transparent to incoming visible light from the sun, yet opaque to the energy radiated from the earth is one of the best understood processes in the atmospheric sciences. 1  This phenomenon, the greenhouse effect, is what makes the earth habitable for life. For students to truly understand the nature and importance of the greenhouse effect, they should understand the answers to these questions: What is a greenhouse and how does it work? How is the earth's atmosphere similar to a greenhouse?
