Question

Which one of the following gases can deplete ozone layer in the upper atmosphere?

• A. Ammonia
• B. Methane
• C. Carbon monoxide
• D. None of the above

Answer 1

The correct option is B Methane

Methane can deplete ozone layer in the upper atmosphere. It acts as a greenhouse gas (a gas that traps heat from the sun within earth’s atmosphere) and it also attacks ozone. At low latitudes, methane in the stratosphere breaks down into hydrogen oxides, which attack reaching the ozone layer reacts with it and leads to the splitting of bonds between ozone.

So, the correct answer is option B.
