Question

U-V radiations from sunlight causes the reaction that produces ______.

Answer 1

U-V radiations from sunlight causes the reaction that produces ozone.

Explanation:

Ultraviolet (UV) rays from the sun act on molecular oxygen (O₂) in the stratosphere to form ozone (O₃). This ozone layer protects living organisms by absorbing most of the harmful UV radiation from the sun, thus preventing it from reaching the Earth’s surface. However, substances like chlorofluorocarbons (CFCs) can break down ozone, leading to ozone depletion and increased UV radiation exposure.
