Where does lightning come from?

Answer by  azchemfreak (95)

Lightning results from the static discharge of electricity that builds up due to frictional action of particles and dust in the upper atmosphere as they come into contact with each other. Exchange of electrons between these particles occurs until the lighting discharges returning the dust to electrical neutrality.

Lightning is caused when a layer of clouds becomes electrically charged. When the charge is large enough, it creates an electric field large enough make regions of the surrounding air conduct. When this happens, negative charges in the clouds move quickly to earth, heating the air until it glows.
