Lightning is an atmospheric discharge of electricity, typically associated with thunderstorms. It is caused by the buildup of electrical charges within a cloud or between a cloud and the ground. When the electrical discharge takes place, it produces a bright flash of light and an accompanying sound, which is thunder.
Lightning can be extremely dangerous and can cause significant damage to both people and property. It is important to take precautions during thunderstorms, such as seeking shelter in a building or car, avoiding water and metal objects, and staying away from open fields and bodies of water.
Despite its dangers, lightning is also a fascinating natural phenomenon that has been the subject of much scientific study. It is still not fully understood and is an active area of research in atmospheric physics.
