Question

what is ozone layer and its depletion

Answer 1

ozone layer is a thin blanket of gases around the earth that protects earth by the uv radiations of sun.

Answer 2

Ozone layer is a layer outside our earth's atmosphere which protects us from harmful Ultra violet rays coming from the sun. It is depleting mainly because of chlorofluorocarbons(CFCs).
