NCERT Solutions for Class 7 Chapter 2 Winds, Storms and Cyclones


Basically, the moving air is called the Wind. A disturbance of the normal condition of the atmosphere, manifesting itself by winds of unusual force or direction, often accompanied by rain, snow, hail, thunder, and lightning, or flying sand or dust is called the Storm. When water vapour changes back to water due to condensation, the heat is released to the atmosphere and warms the air around. This chain of events ends with the formation of a very low-pressure system with very high-speed winds revolving around it. This weather condition called a cyclone.
