Question

Quizplus · Accepted Answer

Ozone formation requires the action of UVB radiation on oxygen molecules. This results in the creation of unstable oxygen atoms that are capable of combining with other oxygen molecules to form ozone (O3). Ozone is also broken down by UVB radiation, which splits the O3 molecules into O2 and individual oxygen atoms. This process is a natural and essential part of the Earth's atmosphere, as it creates a protective layer that shields the planet from harmful UV radiation.
