Answers
Answer:
• Decrease in the concentration of ozone in the stratosphere isliye cause of the formation of Ozone Hole.
Explanation:
• In the upper atmospheric layer of stratosphere a layer of ozone gas (O3 )is present.
• This layer is crucial for our well being because it reflects back the harmful Ultraviolet radiation of the sun.
• The Ultraviolet rays, particularly UV B radiation are very harmful for life on earth. It causes Snow Blindness, along with other problems like skin cancer, and decrease in photosynthetic capabilities in the plants.
• These rays are reflected by the ozone layer and hence we are protected.
• But during the last four decades due to the use of chemicals like chlorofluorocarbons, and other aerosols used in jet fuels, the stratospheric ozone has been declining rapidly.
• These harmful chemicals leads to a chain reaction in which a single molecule of chlorofluorocarbon can destroy upto millions of ozone molecules.
• This has lead to the destruction of ozone and its thinning which is called as Ozone Hole which is particularly prominent over Artic and Antarctic Circle.
