Question

The movement of the air is called _____.
A) Wind
B) Cyclone
C) Thunderstorm
D) All of the above

Answer 1

Hint: Movement is the act or the process of changing the position of something, in this case, air. This could occur due to an external force applied by fans or propellers, or it could be due to the pressure difference between two regions. This pressure difference is also dependent on the difference in humidity, temperature and density.

Complete answer:
The movement of air is referred to by different names depending on its speed, location and other natural phenomena associated with it.

Now let us look into the given options:
Option A) Wind – Wind is a movement of air that occurs when air from the region of high air pressure moves to a region of low air pressure. These winds can be pleasant and at a comfortable speed, and they can also have very high speed (in case of cyclones, hurricanes) and can be devastating. Thus, this option is correct.
Option B) Cyclone – When air moves at a very high speed and at the same time move in a circular or spiral manner it forms a cyclone. These are generally formed due to the Coriolis Effect which is a consequence of the earth’s rotation on its axis. It forces the straight moving air to form a spiral wind. Therefore, this option is correct.
Option C) Thunderstorm – These are strong winds associated with lightning and thunder. In this kind of movement, the warm and moist air moves up rapidly and condenses. This condensed moisture produces heavy rains and sometimes ice pellets or hails. This phenomenon is the movement of air with rainfall and lightning. Thus, this option is also correct.
Option D) All of the above – Therefore, we can see the all the above options are basically movements of air. The only difference is the speed and the degree of danger associated with it. Thus, this is the correct option.

Thus, the correct answer is Option (D) All of the above.

Note: Cyclones, hurricanes, tornadoes and typhoons are some names that people often get confused with. But actually, all of them are the same phenomena, i.e. a circular wind storm. These different names are given depending on which part of the word it has formed. ‘Cyclones’ are found in the Indian Ocean and subcontinent. ‘Hurricanes’ are formed in the Atlantic Ocean and affect eastern America. ‘Typhoons’ originate in the Pacific Ocean. And ‘tornados’ are these same winds that form not in the ocean but on land.
