The Greenhouse Effect

Natural heating of earth’s surface caused by greenhouse gases –CO 2 (Carbon Dioxide) –CH 3 (Methane) –N 2 O (Nitrous Oxide) –H 2 O (Water Vapor) Necessary for life on earth

Solar Radiation: The Electromagnetic Spectrum

The Greenhouse Effect: How it Works Solar radiation reaches the surface and is absorbed or reradiated back into the atmosphere at longer lower energy wavelengths that can not travel back into space but are absorbed and released by the atmosphere.
