The most important agents for Ozone depletion are
Question 9
Answer
A. Methane
B. Nuclear Fallout
C. Nitrous oxide
D. CFC's
Solution
The most important agents for Ozone depletion are Chlorofluorocarbons (CFCs). So, the answer is D. CFC's.
Here's why:
-
Methane (CH4): While it is a potent greenhouse gas, it does not have a significant direct effect on the ozone layer.
-
Nuclear Fallout: This refers to the residual radioactive material propelled into the upper atmosphere following a nuclear blast. While it can have many detrimental environmental effects, it is not a primary cause of ozone depletion.
-
Nitrous oxide (N2O): This is a powerful greenhouse gas and is the largest ozone-depleting substance emitted through human activities. However, it is not as significant as CFCs in terms of ozone depletion.
-
Chlorofluorocarbons (CFCs): These are types of compounds that were widely used in the 20th century as refrigerants, aerosol propellants, and in air conditioners. CFCs are stable in the lower atmosphere but they decompose in the stratosphere due to solar radiation and release chlorine atoms. These atoms are capable of catalyzing the destruction of ozone. Hence, CFCs are considered the most important agents of ozone depletion.
