The
ozone layer is a layer in Earth's atmosphere containing relatively high
concentrations of ozone (O3). The ozone layer can be depleted by free radical
catalysts, including nitric oxide (NO), nitrous oxide (N2O), hydroxyl (OH),
atomic chlorine (Cl), and atomic bromine (Br)
The ozone
layer spreads like a sheet in earth's atmosphere. The sun's rays consists of
most of the rays other than the visible part. It specially consists of UV and
IR rays. Among them UV [ultra violet rays] is the most harmful one to human
skins. It causes skin diseases in contact with human skin. The main function of
ozone layer is to filter these UV rays from the sun and so protecting life. Though
it is a poisonous gas
But the
cloroflurocarbon CFC gas from the refrigerators affect the ozone layer which
results in several holes in the layer
