Question

What is the importance of ozone in the atmosphere? Discuss the factors responsible for its depletion.

Answer

Importance of Ozone in the atmosphere:

1. The ozone layer present in the stratosphere protects the Earth from the harmful ultraviolet radiation of the sun.
2. It helps in maintaining the temperature balance of the earth’s atmosphere.
3. Ozone is also used in medical and industrial applications.

Factors responsible for the depletion of Ozone:

1. Human-made chemicals such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) are used in refrigeration, air conditioning, aerosol sprays, and foam blowing.
2. Increased emissions of nitrogen oxides (NO_x) and volatile organic compounds (VOCs) from industrial activities and transportation.
3. Natural phenomena such as volcanic eruptions and solar flares can also contribute to ozone depletion.
