Question

The term “water pollution” can be defined in several ways. Which of the following statements does not give the correct definition?

A. The addition of undesirable substances to water bodies 

B. The removal of desirable substances from water bodies 

C. A change in pressure of the water bodies 

D. A change in temperature of the water bodies

Answer 1

Pollution in simpler words is any activity that can result in harmful consequences or can cause disruption in normal environmental conditions. Whether it is the addition of undesirable substances or removal of desirable ones, harmful substances are getting accumulated in either way. Also, change in temperature of water bodies can also adversely affect the plants growing in the bodies and indirectly affecting the animal life and disrupting the food chain. However, pressure in the water bodies varies naturally as we move more closer towards the base of the sea, so it doesn’t affect the conditions much.
