Ultraviolet radiation striking the earth is due to the depletion of A. Carbon monoxide B. Carbon dioxide C. Ozone D. Oxygen

The correct answer is C. Ozone.

Ozone is a gas that is found in the Earth’s stratosphere. It absorbs ultraviolet radiation from the sun, which helps to protect life on Earth. However, human activities, such as the release of chlorofluorocarbons (CFCs) into the atmosphere, have caused the ozone layer to deplete. This has led to an increase in the amount of ultraviolet radiation reaching the Earth’s surface, which can cause skin cancer and other health problems.

Carbon monoxide is a gas
