Question

Which of the following changes is not a result of an increase in water pollution?

• A. Increase in the biological activity in water bodies.
• B. Increase in the amount of rainfall and floods.
• C. Increase in the chemical content of water bodies.
• D. Increase in the cases of jaundice and cholera

Answer 1

The correct option is B Increase in the amount of rainfall and floods.

Rainfall occurs because of a continuous movement of water called water cycle. The pollution of water does not affect the processes involved in this cycle. Hence, the increase or decrease in rainfall and floods is not a result of water pollution.
