Cyclones are formed because of the

a. absorbance of heat in the vaporization of water.

b. emission of heat in the condensation of water.

c. absorbance and emission of heat due to inter-conversion of states of water.

d. conduction of wind current.

 

Best Answer

Ans. c

Explanation: Water takes up heat from the atmosphere to change it into vapour. When water vapour changes back to liquid form as raindrops, this heat is released to the atmosphere. This heat warms the air around, which tends to rise and causes a drop in air pressure. More air rushes to the centre of the storm. This cycle is repeated. A very low-pressure system with very high-speed winds revolving around it is formed. This is called a cyclone.
