Question
Identify the gas which is responsible for the depletion of the ozone layer.
- Methane
- Carbon monoxide
- Chlorofluorocarbons
- Sulfur dioxide
Hint:
The ozone layer is present in the stratosphere. It protects the earth from various types of sun rays which cause a lot of damage to the living things on the earth. Some chemicals which release into the environment and cause damage to the ozone layer.
The correct answer is: Chlorofluorocarbons
Chlorofluorocarbons are responsible for the depletion of the ozone layer.
This is the gas released from the air conditioners and reaches the ozone layer because of its lightweight and causes damage to the ozone layer called depletion. Chlorofluorocarbons through free radical formation deplete the ozone layer.
