Lightning. Bolts of cloud-to-cloud and cloud-to- ground lightning. Lightning occurs when a large electrical charge builds up in a cloud,probably due to the rapid movement of water droplets and ice particles in its turbulent interior. The charge induces an opposite charge in a nearby cloud,or is attracted to the oppositely-charged ground,and a few leader electrons travel from one to the other. When one makes contact,there is a huge backflow of energy along the path of the electron. This produces a bright flash of light and temperatures of up to 30,000 degrees Celsius.
