Cloud-to-ground lightning bolts are a common phenomenon—about 100 strike Earth’s surface every single second—yet their power is extraordinary. http: //schools. sd 68. bc. ca/fore/ireland/2006/jr/cloud%20 to%20 ground%20 lightning. jpg

Each bolt can contain up to one billion volts of electricity. http: //www. harkphoto. com/051803 lightning. jpg

This enormous electrical discharge is caused by an imbalance between positive and negative charges. http: //www. lanl. gov/news/albums/safety/lightning_bolt. sized. jpg http: //extend. schoolwires. com/clipartgallery/images/32255088. jpg

During a storm, colliding particles of rain, ice, or snow increase this imbalance and often negatively charge the lower reaches of storm clouds. http: //www. flickr. com/photos/10093223@N 03/4541103706/
Objects on the ground, like steeples, trees, and the Earth itself, become positively charged—creating an imbalance that nature seeks to remedy by passing current between the two charges. http: //www. flickr. com/photos/jaredryanlee/3637911858/

A step-like series of negative charges, called a stepped leader, works its way incrementally downward from the bottom of a storm cloud toward the Earth. http: //www. flickr. com/photos/bluelunarrose/3010025597/ http: //i. pbase. com/g 6/54/14154/2/1516340. ky. AR 8 E 1 g. jpg
Each of these segments is about 150 feet long. http: //www. just-whatever. com/wp-content/uploads/2008/12/lightning_strike_18. jpg
When the lowermost step comes within 150 feet of a positively charged object it is met by a climbing surge of positive electricity, called a streamer, which can rise up through a building, a tree, or even a person. http: //www. lightningsafety. com/nlsi_info/leader. gif
The process forms a channel through which electricity is transferred as lightning. fbcoem. org http: //www. flickr. com/photos/aristides 2/3768393920/
Some types of lightning, including the most common types, never leave the clouds but travel between differently charged areas within or between clouds http: //www. flickr. com/photos/streamer_yam/4302628561/
Other rare forms can be sparked by extreme forest fires, volcanic eruptions, and snowstorms. http: //www. flickr. com/photos/ethanhein/2253205808/

Ball lightning, a small, charged sphere that floats, glows, and bounces along oblivious to the laws of gravity or physics, still puzzle scientists. http: //www. insidesmusic. com/insidesvideo/images/ball-lightning. jpg
Lightning is extremely hot—a flash can heat the air around it to temperatures five times hotter than the sun’s surface. http: //sunearthday. nasa. gov/2007/images/gal_012. jpg
http: //www. guy-sports. com/fun_pictures/lightning_capito
This heat causes surrounding air to rapidly expand vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash. http: //australiasevereweather. com/photography/photos/2008/1014 jd 27. jpg

Lightning is not only spectacular, it’s dangerous. About 2, 000 people are killed worldwide by lightning each year. http: //www. crh. noaa. gov/ilx/lightning/Ltg_deaths. jpg
Hundreds more survive strikes but suffer from a variety of lasting symptoms, including memory loss, dizziness, weakness, numbness, and other lifealtering ailments. This lady was burned at a rock concert at RFK stadium.
