NCERT Solutions for Class 7 Science Chapter 8 Winds, Storms and Cyclones: Solution for winds storms and cyclones Chapter 8 are part of NCERT Solutions for Class 7 Science. The 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.

In 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. You can also check out the NCERT Solutions for other chapters in science or even for other subjects by using the given links on this page. Students are recommended to go through NCERT Solutions for Class 7 to score high marks in their examinations. It is advisable to complete the NCERT Class 7 Science Syllabus to the earliest. Students also must cover all the topics from the NCERT Class 7 Science Books for conceptual clarity.

This will also tell you about some other precautions if you are staying in a cyclone-hit area —

  • Do not drink water that could be contaminated. Always store drinking water for emergencies.
  • Do not touch wet switches and fallen power lines.
  • Do not go out just for the sake of fun.
  • Do not pressurize the rescue force by making undue demands.
  • Cooperate and help your neighbours and friends.

After going through this chapter, you must be able to get the NCERT Solutions of these questions which are mentioned below, as these questions are from the Science book of NCERT.

Q1. Explain why holes are made in hanging banners and hoardings.

Q2. How will you help your neighbours in case cyclone approaches your village/town?

Q.8. Explain, with examples, why we find animals of certain kind living in particular climatic conditions.

Answer: Animals need a particular environment to survive. All the animals have a different and certain environment which suits them to survive.

Example: A polar bear leaves in cold and snowy regions because they have a thick and fat layer of skin which protects them from cold. They cannot survive in the desert area. Similarly, camel leaves in a desert region, they cannot survive in cold regions.
