Question

There is a possibility of melting of polar ice caps and increase in the level of sea water due to:

• A. Depletion of ozone layer
• B. Green house effect
• C. Acid rain
• D. All of the above

Answer 1

Answer: (B)

Green house effect

The greenhouse effect of the earth means the trapping of infrared radiations from the atmosphere and not reflecting it back due to higher levels of carbon dioxide as a major pollutant that traps radiations.

This effect causes the rise in the global temperature resulting in the melting of polar ice caps and rises in sea level.

Option B is correct.
