Ozone-layer is getting depleted because of:
Ozone-layer is getting depleted because of:
The correct option is C Excessive use of man-made compounds containing both fluorine and chlorine
The correct answer is option C: Excessive use of man-made compounds containing both fluorine and chlorine
Explanation for Correct answer:
Ozone layer:
- Ozone is a highly reactive gas that is made of three oxygen atoms which are found in the upper stratosphere and are about 11-16 kilometers above the Earth’s surface.
- Depletion of ozone layer :
- The depletion or reduction in the ozone layer is caused due to the use of various ozone-depleting substances by human beings.
- The industries are the major sources of ozone-depleting substances such as chemical Chlorofluorocarbons (CFCs), carbon tetrachloride, methyl
- chloroform, methyl bromide, nitrogen oxides, halogens, etc.
- The thinning of the ozone layer results in the formation of an ozone hole which means the Ultraviolet rays from the sun directly reach the earth's surface and increase in ultraviolet radiation.
The explanation for the incorrect answer:
option a) Excessive use of automobiles:
The use of automobiles has made life easier for traveling but they have major consequences on the environment, as they are major contributors to air pollution.
option b) Excessive formation of industrial units:
Since the industries have raised the economy and given many benefits to humans, industries are the major contributor to air and water pollution.
option d) Excessive deforestation:
The cutting down of trees for personal as well as community benefits has now become a major health issue for human beings.
Final answer: A correct answer is an option (C)
Excessive use of man-made compounds containing both fluorine and chlorine
The correct answer is option C: Excessive use of man-made compounds containing both fluorine and chlorine
