Which outcome occurs when ultraviolet radiation cleaves O=O bonds in stratosphere?

💡 Explanation

When UV radiation of sufficient energy cleaves the O=O bond in O2, photolysis occurs, producing two oxygen free radicals which react with O2 to form O3 and deplete it via subsequent reactions involving nitrogen oxides. Therefore ozone depletion results, rather than greenhouse effects, acid rain, or global warming, which arise from different molecular processes.
