12. What is the main reason holes are made in hoardings/banners?
A) To let rain cool them
B) To reduce pressure difference and wind force
C) To let lightning pass through
D) To make them lighter
Answer
B) To reduce pressure difference and wind force
13.Why does a balloon inflate when air is blown into it?
[A]. Air exerts pressure in all directions
[B]. The rubber expands due to sunlight
[C]. The rubber becomes magnetic
[D]. It generates heat
Answer
Air exerts pressure in all directions
14. What is atmospheric pressure?
[A]. Pressure due to air around us
[B]. Pressure due to magnetism
[C]. Wind pressure in hurricanes
[D]. Force of gravity on oceans
Answer
A]. Pressure due to air around us
15. Which instrument helps show air pressure effects?

[B]. Rubber sucker
[C]. Magnet
[D]. Spring balance
Answer
[B]. Rubber sucker
16. What causes high-speed winds during a storm?

17. What happens when you blow between two hanging balloons?
[A]. They burst
[B]. They come closer
[C]. They spin
[D]. They move apart
Answer
B) They come closer Explanation:
The air blown between the balloons creates a low-pressure zone. The higher pressure on the outer sides pushes them inward, bringing them closer. This activity in the chapter shows how fast-moving air reduces pressure and causes surrounding air to exert force.
18. What causes thunder during a thunderstorm?
[A]. Rubbing of clouds
[B]. Rapid air expansion
[C]. Friction in trees
[D]. Heat from the ground
Answer
B]. Rapid air expansion
19. What helps lightning form in clouds?
[A]. Charging due to rubbing
[B]. Colliding warm and cool air
[C]. Rising carbon dioxide
[D]. Winds blowing sideways
Answer
A]. Charging due to rubbing
20. What causes a land breeze at night?
[A]. Land cools faster than sea
[B]. Water evaporates rapidly
[C]. Clouds block wind
[D]. Faster rotation of Earth
Answer
Option A
Explanation:
At night, the land loses heat faster than water. So, the air over land becomes cooler and heavier, creating a high-pressure area. The warmer air over the sea rises, forming a low-pressure area. Air moves from land to sea, resulting in a land breeze.
21.In a cyclone, the region of the lowest pressure at the centre, is known as:
(a) The eye of the cyclone
(b) The body of the cyclone
(c) The air of the cyclone
(d) The pressure of the cyclone
Answer
a) The eye of the cyclone
