Ozone layer is getting depleted because of:
excessive use of automobiles
excessive formation of industrial units
excessive use of manmade compounds containing both fluorine and chlorine
excessive deforestation
Ozone layer is getting depleted because of:
excessive use of automobiles
excessive formation of industrial units
excessive use of manmade compounds containing both fluorine and chlorine
excessive deforestation
The correct option is C excessive use of manmade compounds containing both fluorine and chlorine
The correct option is C.
Explanation of the Correct option:
- The majority of the UV radiation from the Sun is absorbed by the ozone layer, also known as the ozone shield, which is an area in the stratosphere between 15 and 30 km above the planet.
- Compared to other areas of the atmosphere, it has a high concentration of ozone, yet it is still relatively low in comparison to other gases in the stratosphere.
- Fluorine and chlorine react with ozone to convert it to oxygen gas.
- Chlorofluorocarbons(CFCs) are a prominent type of ozone destructive gas.
- In the stratosphere, CFC molecules can be broken by UV radiation, freeing the chlorine.
- The chlorine freed in the reaction acts as a catalyst in the ozone removal process.
- A single molecule of chlorine can destroy hundreds of ozone molecules.
- Solvents, spray aerosols, refrigerators, air conditioners, and other items release CFCs.
Explanation of the Incorrect option:
Option A:
Although the pollutants released due to excessive use of automobiles degrade the Ozone layer, it is not significant.
Option B:
The significance of degradation of the Ozone layer due to excessive formation of industrial units is low.
Option D:
Deforestation does not affect the Ozone layer directly but rather in an indirect way.
Final answer: The ozone layer is getting depleted because of the excessive use of manmade compounds containing both fluorine and chlorine.
