How is lightning created?
Lightning is formed during thunderstorms when different charges build up in the atmosphere. Inside a storm cloud, warm air rises while cooler air sinks, causing ice particles and water droplets to collide, which leads to a buildup of static electricity. This static charge eventually discharges as lightning, creating a bright flash and a loud thunder sound.
