Describe the greenhouse effect...?

Question

discribe the greenhouse effect, and factors causing this effect...

Answer 1

The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface. The name comes from the incorrect analogy with the warming of air inside a greenhouse compared to the air outside the greenhouse.The greenhouse effect was discovered by Joseph Fourier in 1824 and first investigated quantitatively by Svante Arrhenius in 1896.

OK, it goes like this: radiation from the sun enters the earth and warms it. The natural cycle is that when radiation enters earth, most of it will be reflected by the ozone layer, the part of the atmosphere where ozone(O3) is abundant. Heat/radiation that passed through the ozone layer will be absorbed by the ground or by the ocean, or is released into the atmosphere and eventually to space. The cycle continues.

The abnormal thing that happens is that when a lot of radiation reaches that earth's surface, mostly due to ozone depletion caused by CF C's, and heat is being trapped and accumulated on the earth's surface,(also caused by CF C's and other air pollutants) causing the phenomenon we call "Global Warming". This change in temperature causes sudden change in climates all over the world. This also contributes to the production of even more typhoons, tornadoes, wild fires, etc. Not to mention depletion of agricultural products.

Answer 2

In a nutshell, the greenhouse effect is a continuous process of heating-up the atmosphere caused by the release of such-known 'greenhouse gases' (mostly carbon dioxide, methane, oxides of nitrogen etc.) which let long-wave solar energy come into the atmosphere but trap the reflected short-wave radiation from the earth. The trapped radiation provokes inner heating of the atmosphere(compare to the principle of glasshouse). Thus, increase in temperature occures.
