Which consequence results when atmospheric methane undergoes photochemical reactions?

💡 Explanation

Increased stratospheric water occurs because methane oxidation yields water vapor through radical chain reactions in photolysis. This chain reaction involves homolytic cleavage, therefore additional water production, rather than decreased ozone.
