# Lightning Lightning is an electrical discharge. **Formation of Lightning:** * Warm air rises and meets cool air. * This movement of air causes electrons to move to different parts of the cloud. * The bottom of the cloud becomes negatively charged, and the top becomes positively charged. * When the difference in charge becomes large enough, an electric discharge happens. * This discharge is called lightning. * Lightning can happen between two clouds or between a cloud and the ground. **Additional Details:** * Static electricity also exists in clouds. * The process of warm air rising and cool air falling creates the movement of electrons. * This movement results in the different charges in the cloud. * A large discharge happens between oppositely charged areas (cloud to cloud or cloud to ground), causing lightning and thunder.
