How is the light from sun trapped by gren house gases? and what are the greenhouse gases.Please name them.?

Answer 1

It's not really the light from the sun that's trapped, but rather the infared heat that travels with the light. There are many greenhouse gasses, including water vapour, carbon dioxide, nitrous oxides, CFCs, methane, ozone, and many more.... A simple google search might help you out a bit more.

Here's a neat animation on the subject:

Answer 2

The two major green house gases are water vapour and carbon dioxide.The other less important gases are methane, ozone, chlorofluorocarbon and nitrogen oxide.Water vapour,carbon dioxide methane and nitrous oxide occur in nature.But the other gases are man-made.
These gases prevent heat radiation from escaping into space by absorbing the infra-red radiation.Green house effect is thus achieved.
More details are given below.
Water vapour and carbon dioxide are powerful absorber of heat radiation that is emitted by the earth's surface(terrestial radiation).It is because of this property of these gases that the atmosphere near the surface does not cool rapidly when there is a layer of low or medium cloud cover.The heat radiation from the earth's surface is readily absorbed by the cloud layer and re-radiated back to the earth's surface with the result there is less cooling of the surface and the atmosphere near the surface becomes warm and sultry.The effect of these gases and the cloud layer is called the "greenhouse effect" .The other green house gases also similarly absorb the heat radiation and keep the atmosphere near the surface warmer.

Answer 3

It is not. On Venus the CO2 reflects the heat back into space,but here they want to say it is reflected back to earth. CO2 is a very heavy gas's and is so heavy that it will smother a fire. 98% is withen 20 ft. of the earth's surface. Plants need CO2 as bad as U need oxygen. So the earth'e3 CO2 has not increased but a few parts per million and most of that is near the earth.
Methane is a light gas and will go very high before the sun light oxidizes it. Proof there are no large lakes of methane in our upper atmosphere as the first aircraft through it would make a big BOOM.

Answer 4

Heat from the sun is blocked, not trapped by greenhouse gasses.

They trap the heat coming from the Earth--sounds minimal but consider Venus. Its the hottest planet in the solar system by a huge margin, yet all it does is trap its internal heat and reflect the heat from the sun back out into space due to its cloud layer.

Answer 5

C O2,CH4,water vapour are greenhousegases.they are very imp for our life without that the earth would be a colder region,the trap the solar radiation . some of it get absorbed & some of it gets reflected it is these gases which prevent that rays (infra red rays) from escaping back but due to human activites a lot of green house gases are collected in our atmosphere which leads to green house effect & ultimately to global warming
