The ozone layer is one of the layers present in the earth's atmosphere, between 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.
