Question

Which rays strike on the earth due to the depletion of the ozone layer?

• A. Ultraviolet
• B. Infrared
• C. Visible light
• D. Microwaves

Answer 1

The correct option is A

Ultraviolet

Explanation for correct option:

Option A

Ozone layer depletion:

• Ozone depletion refers to the slow and steady decline of the ozone concentration in the earth's atmosphere.
• 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.
• If the ozone layer was absent, then UV rays directly reached to the earth's surface, and due to this millions of people would develop skin diseases and may have weakened immune systems.

Therefore, option A is correct.
