How are ice crystals and water droplets related to lightning during a thunderstorm?
What will be an ideal response?
Answer: The key to the production of lightning seems to be the build-up of negatively charged pieces of water at the bottoms of thunderstorm clouds. This phenomenon is due to the great turbulence in thunderstorms causing collisions and breakage of pieces of water. Other parts of the clouds are positively charged as is the ground and this can cause and electrical discharge.
