Detailed explanation-1: -Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules.

Detailed explanation-2: -Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons-gases formerly found in aerosol spray cans and refrigerants-are released into the atmosphere (see details below).

Detailed explanation-3: -Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.

Detailed explanation-4: -Human activities are the main cause of the depletion of the ozone layer. It occurs due to the excessive use of the man-made chemicals that are bromine and chlorine which release from the man-made compounds such as: Chlorofluorocarbons (CFCs) CFCs (chlorofluorocarbons)

Detailed explanation-5: -Ozone occurs both in the Earth’s upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Called stratospheric ozone, good ozone occurs naturally in the upper atmosphere, where it forms a protective layer that shields us from the sun’s harmful ultraviolet rays.
