Lightning strike over a rural area. Lightning occurs when a large electrical charge builds up in a cloud. This is thought to be due to the rapid movement of water droplets and ice particles. The charge induces an opposite charge on the ground, and a few 'leader electrons' travel to the ground. When one electron contacts the ground, there is a huge backflow of energy between cloud and ground, producing a bright flash, and temperatures of up to 30, 000 degrees Celsius. | |
