What is the ozone layer? What is its function?
Ozone layer is a protective layer in the stratosphere. It protects the earth's inhabitants from the harmful UV rays of the sun which if not blocked may cause skin cancer.

The ozone layer is a region of the Earth's stratosphere that contains a high concentration of ozone (O3) molecules. Its function is to absorb the majority of the Sun's ultraviolet (UV) radiation, particularly harmful UV-B and UV-C rays, thereby protecting life on Earth from the damaging effects of excessive UV exposure, such as skin cancer, cataracts, and damage to marine ecosystems.
