How is the protective ozone shield formed? What causes its natural breakdown?
What will be an ideal response?
"Ozone is formed in the stratosphere when UV radiation acts on oxygen molecules. The high-energy radiation first causes some molecular oxygen to split apart into free oxygen atoms, and these atoms then combine with molecular oxygen to form ozone." This reaction is reversible. "When ozone absorbs UVB, it is converted back to free oxygen and molecular oxygen."
