← ScienceWhich consequence results when intense UV radiation strikes stratospheric ozone molecules?
A)Increased free radical concentration✓
B)Decreased tropospheric temperature
C)Enhanced nitrogen oxide production
D)Reduced greenhouse gas absorption
💡 Explanation
UV radiation breaks the O=O bond through homolytic cleavage; creating free radicals, because photolysis occurs. Therefore free radicals concentration increases, rather than temperature dropping, which could occur under less absorption of UV rays.
