Lightning

Today, I became aware of how lightning forms during a storm. Thunderstorms usually come after hot days.  Warm, moist air rises quickly and forms comulonimbus clouds.  Inside the clouds, water droplets and ice particles rub and hit against each other, creating static electricity. Positive chargers accumulate at the top of the clouds, and negative charges accumulate at the bottom of the cloud. The ground is positively charged. Electricity flows in between the ground and the clouds, creating a difference in electricity.  When this difference is too big, it is released in the form of lightning.
