Explanation:
Have you ever watched a lightning storm in awe?
Join the crowd.
Oddly, nobody knows exactly how
lightning is produced.
What is known is that charges slowly separate in some clouds causing rapid electrical
discharges
(lightning), but how electrical charges get separated
in clouds remains a topic of much research.
Lightning usually takes a
jagged course,
rapidly heating a thin column
of air to about three times the surface temperature of the
Sun.
The resulting shock wave starts
supersonically and decays into the
loud sound known as
thunder.
Lightning bolts are common in clouds during rainstorms, and on average
44 lightning bolts occur on the
Earth every second.
Pictured, over 60 images were stacked to capture the flow of lightning-producing
storm clouds in July over
Colorado Springs,
Colorado,
USA.
