The ozone layer in the stratosphere plays a vital role in shielding life on Earth from harmful ultraviolet (UV) radiation. Ozone (O3) is formed when oxygen molecules (O2) in the stratosphere are split into individual oxygen atoms by solar UV radiation. These oxygen atoms then combine with other oxygen molecules to form ozone.

The ozone layer absorbs most of the Sun's harmful UV-B and UV-C radiation, preventing these high-energy rays from reaching the Earth's surface. UV radiation is known to cause skin cancer, cataracts, and other harmful effects on living organisms. Therefore, the presence of the ozone layer is crucial for protecting life on Earth and maintaining the delicate balance of ecosystems.
