Lightning is a large electric spark in the sky.
Lightning takes place between a cloud and the ground. Lightning occurs when
positive and negative particles split. Lightning that strikes the earth has one
or more discharges that are called strokes. A lightning strike has 100 million
volts or 60,000 F. Lightning occurs in cumulonimbus clouds. There are many kinds
of lightning. Forked lightning is a flash with many other flashes off the side.
Streak lightning is one crooked line. Ribbon lightning is a pair of parallel lines of light. Bead
lightning is a lightning flash that bursts into a dotted streak as it
disappears. Some lightning does not even hit the ground, such as heat
lightning and sheet lightning.
