light·ning
(līt′nĭng) A flash of light in the sky caused by an electrical discharge between clouds or between a cloud and the Earth's surface. The flash heats the air and usually causes thunder. Lightning may appear as a jagged streak, a bright sheet, or, in rare cases, a glowing red ball.
Did You Know? The energy within a bolt of lightning is so great that it heats the air around it to temperatures up to five times greater than that of the surface of the sun, or 55,000°F (30,000°C). The rapid expansion of this superheated air is what creates the sounds we call thunder. The sounds travel to us more slowly than the light from lightning, so it is possible to estimate how far away a lightning strike is by timing the gap between when you see the lightning and when you hear the thunder it has produced. Count the seconds from when you see the flash until you hear the thunder, and divide this number by five. The result will be the number of miles you are from the point of the strike.
