Question

Ozone is important to mankind because it?
1. Creates a protective coverage against ultraviolet rays
2. Releases hydrogen in the atmosphere
3. Releases oxygen in the air
4. Maintains the temperature of the earth

Answer 1

Correct Answer - Option 1 : Creates a protective coverage against ultraviolet rays

The correct answer is Creates protective coverage against ultraviolet rays.

• Ozone is important to mankind because it creates a protective coverage against ultraviolet rays.
  • Formula Ozone is- O₃.
  • The ozone layer is a thin part of the Earth's atmosphere that absorbs almost all of the sun's harmful ultraviolet rays.
  • The ozone layer is found in the stratosphere.
  • The stratosphere is the mass of protective gases clinging to our planet.
  • The ozone layer acts as a shield for life on Earth.
  • The ozone layer only makes up 0.00006 percent of Earth’s atmosphere

• The ozone layer is getting thinner because of chemicals called chlorofluorocarbons (CFCs).
  • Due to this reason nowadays hydrochlorofluorocarbons (HCFCs) are used in place of CFCs.
    • They also deplete Ozone but to a much lesser extent.
  • CFCs are everywhere, mostly in refrigerants and plastic products.
  • They are broken up by ultraviolet radiation in the stratosphere, releasing chlorine atoms, which are able to destroy ozone molecules.
  • CFCs are non-toxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine.​
  • “Ozone holes” are popular names for areas of damage to the ozone layer.
  • The ozone layer is thinnest near the poles due to very low temperatures.
