Little streamers come down from the cloud and up from the ground. If two of these streamers should meet, you get a current of electricity and you have lightning. These little rivers of electricity are brighter than ten million one-hundred watt light bulbs. They travel at a speed of SIXTY MILES PER SECOND! The actual lightening bolt is brief, but one bolt can power a light bulb for about a month. The path of a lightning bolt can reach up to fifty thousand degrees!
Thunder is the deep rumbling
sound that occurs after a flash of lightning. The sound is created
by the violent explosion of air that has been heated by lightning.
The air is heated quickly when the electrical charge of lightning
passes through it. This immense heat makes the air molecules expand.
As the molecules need more room, they crash into cooler air that
creates an air wave. This air wave is the sound of thunder. Thunder
has many different sounds, depending on where you are and what
the lightning does. It can be crackly, rumbly, or just one large
crack might be heard.
