At higher levels in the atmosphere the UV radiation splits some oxygen molecules (O2) into free oxygen atoms which combines with oxygen molecules (O2) to form ozone. But ozone also absorbs harmful components of sunlight, known as "ultraviolet B", or "UV-B". Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere.
