Greenhouse Effect/Greenhouse Gases Updated!
The greenhouse effect is the retention by Earth's atmosphere, in the form of heat, some of the energy that arrives from the sun as light. Certain gases, termed greenhouse gases, including carbon dioxide (CO2) and methane (CH4), are transparent to most of the wavelengths of light arriving from the sun but are relatively opaque to infrared or heat radiation; thus, energy passes through the Earth's atmosphere on arrival, is converted to heat by absorption at the surface and in the atmosphere, and is not easily reradiated into space. The same process is used to heat a solar greenhouse, only with glass, rather than gas, as the heat-trapping material. The greenhouse effect maintains Earth's surface temperature within a range...Read more
