Write short note on Green House Effect.

Explanation

Due to energy gained from Sun surface and substances of Earth become hot according to their absorptivity.
These hot substances emit infrared rays from them. These rays cannot get out of the atmosphere due to their high wavelength.
These radiations are mostly absorbed by gases like carbon dioxide `(CO_(2))`, methane `(CH_(4))`, nitrus oxide `(N_(2)O)`, chlorofloro carbon `(CFVl)` and tropospheric ozone `(O_(3))` and heated.
These hot greenhouse gases produce infrared rays again and give more energy to Earth. As a result, surface of Earth remains warmth and temperature remains constant.
Due to this intensity of radiations from surface.
The cycle of this process continuous till increases the radiation is not obtained for absorption.
As a result temperature of Earth surface and atmosphere increases it is called green house effect.
Infrared rays are also called heat rays as they give heat. Due to heat rays warmth atmosphere is felt in winter in cloudy atmosphere instead of cold Temperature of Earth would be `-180^(@)C` withous green house effect.
Due to mankind activities, the concentration of green house gas is increased which makes the Earth hotter. So, that the temperature of Earth is increased by `0.3^(@)C` to `0.6^(@)C`.
After half century, temperature of Earth will be higher by `1^(@)C` to `3^(@)C` than today. It will be a reason of difficulty form mankind, plants and animals due to global warming.
As a part of global warming amount of polution is increasing consistenly and dangerously due to which the ice slabs will melt quickly hence the level of sea will high and atmosphere will be changed.
Many cities are in fear to be sinked in sea.
Desert areas will be increased due to more green house effectts.
Whole world should give sufficient efforts to decrease effect of global warming.
