6. What is meant by 'Ozone Layer Depletion'? Mention the role played by
Ozonosphere.
Answers
Answer:
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 15 to 35 kilometers (9.3 to 21.7 mi) above Earth, although its thickness varies seasonally and geographically.

Hope this may help you.
Answer:
It was detected through satellite images conducted by NASA and USA,that ozone deletion is 'ozone hole'.
Ozonosphere help in reduceing the ultraviolet rays that directly comes from the sun.
These ultraviolet rays are very harmful for living beings and a hole in ozone means a lot destruction to living organism
Explanation:
Chlorofluorocarbon(CFC) are regarded as the reason for the 'ozone hole' near Antarctica . CFC gases are used in refrigerator, aircraft and air conditioners. CFC compounds escape into the atmosphere and finally break down in the stratosphere. They produce chlorine atoms which destroy the 'Ozone layer'.
