Winds, Storms and Cyclones | ExerciseWhen we blow a balloon, it becomes tight. If we try to fill more air then the balloon will burst after an extent. This happens because the air exerts pressure. When wind blows at a high speed, the fringes of windows and doors of our houses move.

Answer 2

Answer:

Explanation:

1st...When we blow a balloon, it becomes tight. If we try to fill more air then the balloon will burst after an extent. This happens because the air exerts pressure. When wind blows at a high speed, the fringes of windows and doors of our houses move.

2nd...Whenever wind blows then it is a common phenomenon that the fringes of the doors and windows move vigorously and this happens because of air exertaing pressure on the doors and windows.

When we blow a baloon then the baloon grows bigger and hard. If we still blow the balloon then it bursts.

This indicates that air exerts pressure on the interiors of the balloon.
