(C)Long ago, people made up interesting stories to explain what causes lightning and thunder. To many people, lightning and thunder can be very frightening especially because they often happen just before a big rainstorm. Actually, having a better understanding of something can make it less frigh...

Lightning Science What causes lightning in a volcanic ash cloud? Here is an idealized sequence of events that leads to lightning: Starting state (particles might have already been charged by some previous process). Collisions lead to charge separation. For this to happen there has to be some di...
But since the clouds are huge, they sometimes make big sparks called lightning. Lightning heats the air around it, which expands. Then the air cools and rushes back in from both sides. The closer the lightning is, the sooner peop...
What Causes Lightning? Lightning is caused by the collision of ice particles with a cloud with an excessive negative charge. This strong charge repels electrons towards the ground, turning it into a positively charged end. Lightning discharges to the ground as a powerful force that races towards ...
Causes of lightning: Lightning occurs when electricity builds up during a thunderstorm. Lightning bolts are responsible for those zigzag patterns that you see in the sky.
Bead Lightning Bead lightning is a form of cloud-to-ground lightning in which the lightning is broken up into a series of short, powerful bursts of electricity and resembles a string of beads. Scientists are not quite sure about what causes bead lightning but they believe that as lightning co...

It's well-known that lightning is an electric current—a quick, powerful burst of charge that flows within a cloud or between a cloud and the ground. But surprisingly, scientists still don't fully understand how the initial spark forms that generates suc
