The ozone layer is primarily found within the stratosphere, which is the second layer of the Earth’s atmosphere above the troposphere.
The stratosphere extends from about 10 to 50 kilometers above the Earth’s surface. The ozone layer itself is situated between approximately 15 and 35 kilometers above the surface.
This region is significant because it contains a higher concentration of ozone (O3) compared to other layers of the atmosphere. The ozone layer plays a crucial role in absorbing the majority of the sun’s harmful ultraviolet (UV) radiation, which helps protect life on Earth.
Without this layer, living organisms would be exposed to higher levels of UV radiation, leading to increased risks of skin cancer, cataracts, and other health issues, as well as negative impacts on ecosystems.
