Lightning is the result of air molecules being superheated (up to approximately 54,000° F, or six times the surface temperature of the sun!) by a massive surge of electricity. As such, lightning is always visible if you're close enough, though it may be obscured by opaque and semi-opaque materials such as clouds, smoke, soot, heavy snow, tornadic debris, etc.
As a general rule of thumb, if you're close enough to hear the thunderclap, you were probably close enough to see the lightning. (And if you can hear thunder, you're at risk of being struck by lightning, so take shelter immediately.)

What are some examples of electric discharge?
Lightning would be one.And the sparks of static electricity you see are too.
Is lightning a light source or reflector?
Lightning is not a traditional light source like the sun or a light bulb, as it does not produce light through a thermal or chemical process. Instead, lightning is an electrical discharge that generates light as a result of the rapid heating and ionization of air molecules along its path. Therefore, lightning can be considered a light source in the sense that it emits light, rather than a reflector that simply bounces light off its surface.
Lightening is caused by?
Lightning is static electricity.
How does lighning work?
Lightning rods provide an earthed conduit for the charge to flow along. The energy moves through the rod, through the attached cable and into the ground, dissipating with no ill effects. This as opposed to going through the house or building and setting parts on fire or destroying the circuitry.
Which is NOT a sign that a double displacement reaction has occurred?
1) Formation of a precipitate 2) Usually there is a colour change. 3)Neutralization reactions (also a double displ. reaction) involving an acid and a base form water which is a clue.
