Cause and effect. - Moving air in updrafts and down drafts causes electrical charges to build up in clouds.?

Question

What effect does this build up of charge cause?

Answer 1

Lightning and thunderstorms!! ^-^

Answer 2

Lightning and thunder accompanied by cool air descending and spreading in all directions after reaching the surface and sometimes followed by precipitation.

Answer 3

As the clouds float around the small particles in side rub against one another exchanging electrons (static electricity).  As this 'rubbing' goes on the charges continue to build to massive amounts.  If enough of a charge is developed (that is, enough to overcome the natural electrical resistance of air), then a static discharge takes place.  That's lightning!
