Question 3

What is not true about air?

a) It makes the windmill rotate.

b) It helps in the movements of airplanes.

c) Birds can fly due to the presence of air.

d) It has no role in the water cycle.

Answer 1

d) is the desired option.

Water evaporates from the water bodies and enters the air in the form of water vapour, which later gets condensed in the form of clouds. This is the role played by air in the water cycle. The other options are correct.

The energy associated with the wind rotates the windmills, which can be used to generate electricity. Birds and airplanes fly due to the presence of air.
