Question

write a detailed note on greenhouse effect ? answer in points

Answer 1

Greenhouse effect is caused by various green house gases in the atmosphere. All the green house gases available in the atmosphere allow the passage of short wavelengths of visible lights of sun through the transparent medium, absorb heat and check the infrared radiations of longer wavelength to pass back to the space. In this way green house gases trap the heat from long wavelength radiations which result in increased temperature of the earth’s surface. Our earth’s surface is getting warm day by day causing climate change, weather patterns change and declining the healthy living of human beings, plants and animals.

Answer 2

This increase in heat is called the greenhouse effect. Common examples of greenhouse gases, listed in order of abundance, include: water vapor, carbon dioxide, methane, nitrous oxide, ozone, and any fluorocarbons.
