Question

ozone layer is depleted by.......​

Answer 1

Answer:

Ozone layer is getting depleted because of Cfcs. (Chlorofluorocarbons)

Answer 2

Answer:

cfcs

Explanation:

Ozone-layer is getting depleted because of excessive use of man-made compounds containing both fluorine and chlorine.

The main reason being CFC molecules are made up of chlorine, fluorine and carbon atoms which are extremely stable. This extreme stability allows CFC's to slowly make their way into the stratosphere (most molecules decompose before they can cross into the stratosphere from the troposphere).

This prolonged life in the atmosphere allows them to reach great altitudes where photons are more energetic. When the CFC's come into contact with these high energy photons, their individual components are freed from the whole.

Cl+O 3 →ClO+O 2

ClO+O 3 →Cl+2O 2
