Question

The term “Ozone hole” refers to

• A. The thickening of ozone in ozone layer
• B. The small holes scattered in ozone layer
• C. The thinning of the ozone layer
• D. Trapping the UV radiations coming from the Sun

Answer 1

The correct option is C The thinning of the ozone layer

The ozone layer is present in the stratosphere and provides protection against harmful UV rays. Ozone hole is actually the thinning of the ozone layer majorly due to chlorofluorocarbons (CFCs). This thinning of the ozone layer leads to global warming. The reduction in the concentration of ozone in the atmosphere is called ozone depletion.
