Ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it. Ozone is created when oxygen (O2), is split apart by ultraviolet energy emitted by the sun into single oxygen atoms. The single oxygen atoms can rejoin to make O2, or they can join with O2 molecules to make ozone. Continue reading
