Question

Quizplus · Accepted Answer

Lightning is the result of the buildup of electrical-energy polarity within clouds. When the difference in electrical charge between two parts of a cloud or between the cloud and the ground becomes too great, a spark of electricity (lightning) occurs. Thunder, on the other hand, is the sound caused by the rapid expansion of air that is heated by the lightning's electrical energy.
