'''Lightning''' is a bright flash of [[electricity]] produced by a [[thunderstorm]]. All thunderstorms produce lightning and are very dangerous. If you hear the sound of [[thunder]], then you are in danger from lightning. Lightning kills and injures more people each year than [[hurricane]]s or [[tornado]]es; between 100 to 200 people. Lightning is an electric current. Within a thundercloud way up in the [[sky]], many small bits of [[ice]] bump into each other as they move around in the [[air]]. All of those collisions create an electric charge. After a while, the whole [[cloud]] fills up with electrical charges. The [[proton]]s form at the top of the cloud and the [[electron]]s form at the bottom. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as [[mountain]]s, [[people]], or single [[tree]]s. The charge coming up from these points eventually connects with a charge reaching down from the clouds and lightning strikes.
