What is Lightning?



  • Lightning is an electric current that forms in Cumulonimbus clouds
  • As the warm air underneath rises through the cold air above the water and ice particles collide and create static electricity
  • The heavier negative particles sink to the bottom of the cloud and the lighter, positively charged particles rise to the top
  • As the charges get large enough, an electric current (lightning) occurs between the two charges within the cloud
  • Most lightning occurs within the cloud, but the ground can also create a buildup a concentrated positive charge around anything sticking up
    (mountains, trees, lightning conductors, and even people).
  • The grounds positive charge will attract to the negatively charged bottom of the cloud and create a current between the ground and cloud.
