NCERT Solutions for Class 7 Science Chapter 8 Winds, storms and cyclones

 

NCERT solutions for Class 7 Science Chapter 8 Winds, Storms and Cyclones: Air around us exerts pressure and it expands on heating and contracts on cooling. Warm air rises up, whereas comparatively cooler air tends to sink towards the earth’s surface. In NCERT solutions for Class 7 Science Chapter 8 Winds, Storms and Cyclones, you will get to know about how  as warm air rises, air pressure at that place is reduced and the cooler air moves to that place. The moving air is called wind. Uneven heating on the earth is the main cause of wind movements. Winds carrying water vapour bring rain. High-speed winds and air pressure difference can cause cyclones. It has become easier to monitor cyclones with the help of advanced technology like satellites and radars. In CBSE NCERT solutions for Class 7 Science Chapter 8 Winds, Storms and Cyclones, you will also learn that self-help is the best help. Therefore it is better to plan in advance and be ready with defence against any approaching cyclone. The solutions of NCERT for class 8 scence chapter 8 Winds, Storms and Cyclones are prepared in a very comprehensive manner. You can also check out the solutions of NCERT for other chapters in science or even for other subjects by using the given links on this page.
