The correct answer is It absorbs a large proportion of the sun's ultraviolet radiation.

  • It absorbs a large proportion of the sun's ultraviolet radiation.

Key Points

  • The part of the stratosphere, in which there is a concentration of ozone, is often called Ozonosphere.
  • The ozone layer absorbs a large proportion of the sun's ultraviolet radiation.
  • The ultraviolet rays are of three types that are:
    • UVA
    • UVB
    • UVC
  • UVA and UVB are responsible for skin damages.
  • UVC has the shortest wavelength and hence never reaches earth.

Additional Information

  • ​Composition of the Atmosphere:
    • Nitrogen–78%, Oxygen–21%, Argon–0.93%, Carbon dioxide–0.03%, Neon–0.0018%, Helium–0.0005%, Ozone–0.006%, Hydrogen–0.0005%.
  • Montreal Protocol, 1987 on Substances that Deplete the Ozone Layer
    • It is an international treaty designed to protect the ozone layer from Chlorofluorocarbons (CFCs).
