Which of the following statements is not correct?

  1. (a) Phosphates enhance the growth of algae in surface water.
  2. (b) Melting of the polar ice cap will result in a rise in sea levels.
  3. (c) Heavy metal toxicity can result from the presence of metal compounds of lead, cadmium, and mercury in water supplies.
  4. (d) Reverse osmosis is a good way to effect desalination.

Interpretation Introduction

Interpretation: It should be identified from the following statement is correct or not.

Concept Introduction:

Explanation of Solution

Reason for correct option

(b) Melting of the polar ice cap will result in a rise in sea levels.

When ice on land slides into the ocean, it displaces ocean water and cause sea level to rise .

When ice melts, water level does not rise an additional amount because the freshwater ice displace the same volume of water as it would contribute once it melts.

This option hold good and it’s a true fact.

Hence the correct option is option b.

Reasons for incorrect options:

Write all the incorrect, the except option (b)...
