Key words of chapter wind storms and cyclones
  • 1 answers

  • Air exerts pressure and expands on heating and contracts on cooling
  • Warm air rises up, and the comparatively cool air tends to sink towards the earth’s surface
  • When warm air rises up, the air pressure at that place becomes less and cooler air moves toward that place
  • Air moves from a region of high pressure to a region of low pressure
  • Moving air is called wind
  • Wind carrying water vapour brings rain
  • Wind movement is caused because of the uneven heating of the earth’s surface
  • Cyclones are huge revolving storms caused by winds blowing around a central area of low atmospheric pressure
  • Tracking and monitoring cyclones have improved with technology and communication
  • Self-help is the best help , thus it is better to plan in advance and be ready with defence against any approaching cyclone
