Question 11

What is greenhouse gas? What is the contribution of methane in causing greenhouse effect?

Solution 11

Some components of the atmosphere such as water vapour, carbon dioxide, nitrous oxide and methane absorb heat energy reflected by the earth's surface and hence increase the average atmospheric temperature. These gases are called greenhouse gases.

Methane contributes to the greenhouse effect to an extent of 19%, and the concentration of methane has been increasing at the rate of 1.5% per year.
