Question

list two causes of depletion of ozone layer in points

Answer 1

Answer:

Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion. These are released by solvents, spray aerosols, refrigerators, air-conditioners, etc. The molecules of chlorofluorocarbons in the stratosphere are broken down by the ultraviolet radiations and release chlorine atoms.

Ozone-Depleting Substances: Sources

Halons: Fire-extinguishers

Methyl chloroform: Adhesives, aerosols

Answer 2

                  Depletion of ozone layer.

Two main causes of depletion of ozone layer are:-

• Manufactured chemicals
• Manufactured halocarbon refrigerants.

Extra information:-

Ozone depletion consists of two related events observed since the late 1970s. Earth's atmosphere, and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health
