Question : The ozone layer is formed due to reactions of:
Option 1: oxygen and ultraviolet rays
Option 2: carbon dioxide and layers of the atmosphere
Option 3: cosmic rays and layers of atmosphere
Option 4: infrared rays and ultraviolet rays
Correct Answer: oxygen and ultraviolet rays
Solution : The answer is oxygen and ultraviolet rays.
Ozone is generated when oxygen molecules (O 2 ) combine with ultraviolet (UV) light from the sun. Three oxygen molecules combine to generate two ozone molecules in the process. 3O 2 + UV radiation → 2O 3 ; this reaction takes place in the stratosphere.
Ozone is essential for absorbing and shielding a major percentage of the sun's UV rays from reaching the Earth's surface, safeguarding living organisms from the destructive effects of excessive UV radiation.
