Question

The supersonic jets cause pollution by the thinning of:

• A. ${\mathrm{CO}}_2$ layer
• B. ${\mathrm{SO}}_2$ layer
• C. ${\mathrm{O}}_3$ layer
• D. ${\mathrm{O}}_2$ layer

Answer 1

The correct option is C

${\mathrm{O}}_3$ layer

Explanation for correct option:

Option C

• Most of the high-level supersonic aircraft produce harmful pollutants in the stratosphere.
• This leads to the thinning of the ozone layer or causes ozone layer depletion.
• The ozone layer absorbs most of the harmful ultraviolet rays of the sun and prevents them from reaching the earth's surface. But due to a decrease in the concentration of ozone in the air, the harmful ultraviolet rays can enter the earth's lower atmosphere to cause skin cancer, cataracts in the eyes, sunburn, etc.
• It can also increase the earth's temperature, leading to global warming.

Therefore, option C is correct.
