Question: Explain the role of uv radiation in producing ozone layer?

UV radiation plays a crucial role in producing the ozone layer in the Earth's stratosphere. When UV radiation from the sun strikes an oxygen molecule (O2) in the stratosphere, it can cause the molecule to split into two separate oxygen atoms (O). These oxygen atoms can then combine with other oxygen molecules to form ozone (O3). The ozone layer acts as a protective shield against harmful UV radiation, absorbing most of the UV radiation that reaches the Earth's surface. Without the ozone layer, life on Earth would be exposed to high levels of UV radiation, which can cause skin cancer, cataracts, and other health problems.
