उत्तर
Ozone gas is continuously formed in the stratosphere by action of UV rays on molecular oxygen.
Explanation:
Ultraviolet (UV) radiation in the stratosphere breaks down molecular oxygen (O2) into atomic oxygen (O). Ozone (O3) is created when the atomic oxygen joins forces with another O2 molecule. Thus, when UV photons interact with molecular oxygen, ozone is created.
