Question

What is greenhouse effect?

Answer 1

You must know that Green houses are made for good growth of plants by trapping Infra-red or Heat rays from the Sunlight. Infra-red rays have high wave-length, hence, they have low frequency, hence while being reflected their frequency decreases even more and are trapped by the glass-walls.

This also happens with the Earth, but here, Heat rays are trapped by Green-house gases like $SO_2, CO_2, NO_2  etc.$, which causes increase in the Earth's atmospheric temperature, known as Global Warming.

Answer 2

HEY MATE HERE IS YOUR ANSWER:-


The trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Most answers here concentrate on how heat from the Earth’s surface is absorbed and re-emitted or otherwise trapped by various gases in the atmosphere. It is then supposed that some of this heat increases the temperature of the Earth’s surface (from where it came in the first place). Various analogies are used to explain this phenomena such as blankets, back radiation and so on.



How it is created :-

The emission of carbon dioxide is excessive amount in atmosphere creates green house effect.
