PPT-OZONE LAYER OZONE LAYER

The ozone layer or ozone shield is a region of Earths stratosphere that absorbs most of the Suns UV radiation It contains high concentration of ozone O3 It is a pale blue gas at room temperature. Stratospheric ozone: the natural cycle Produced in stratosphere by dissociation of oxygen atoms exposed to short-wave radiation Reaction accounts for most of adsorption of ultraviolet sunlight () as w DEPLETION.
