Question

What is the main reason of ozone layer depletion?

Answer 1

Ozone layer

• The ozone layer is one of the layers present in the earth's atmosphere, between $15\mathrm{to}30\mathrm{Km}$ above the surface.
• The ozone layer is mainly found in the lower portion of the stratosphere.
• The ozone layer helps living organisms from the ultraviolet rays of the sun.

Ozone layer depletion

• Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere.
• Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion.
• UV rays degrade the chlorofluorocarbon molecules in the stratosphere and release chlorine atoms as a result. Ozone is destroyed when these atoms interact with it.

• Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health.
• The ozone layer can degrade in the presence of chlorofluorocarbons.
