Definition:
 The phenomenon whereby the earths atmosphere traps solar radiation, caused by the presence in the atmosphere of gases such as ampere-second dioxide, water vapor, and methane that allow incoming sunlight to pass finished merely absorb heat radiated back from the earths push through. The application of this effect to a planets atmosphere; carbon dioxide and some other gases in the planets atmosphere can absorb the infrared radiation emitted by the planets surface as a result of exposure to solar radiation, thus increasing the mean temperature of the planet.
Solar energy, mostly in the form of short-wavelength visible radiation, penetrates the atmosphere and is intent by the Earths surface. The het up(p) surface then radiates some of that energy into the atmosphere in the form of longer-wavelength infrared radiation. Although some of this radiation escapes into space, much of it is absorbed by greenhouse gases in the lower atmosphere, which in secrete re-radiate a portion back to the Earths surface. The atmosphere thus acts in a manner roughly analogous to the glass in a greenhouse, which allows sunlight to penetrate and warm the plants and soil but which traps most of the resulting heat energy inside.
The greenhouse effect is natural to life on Earth; however, the intensification of its effect due to change magnitude levels of greenhouse gases in the atmosphere is considered to be the main bestow factor to global thaw. It is called as greenhouse effect.
| Global warming refers to the increase in the average temperature of the Earths near-surface air and oceans in upstart decades and its projected continuation.The global average air temperature near the Earths surface has rise 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last 100 years. The Intergovernmental Panel on Climate Change (IPCC) concludes, most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the...If you motivation to get a full essay, order it on our website: Orderessay
