Which force is most directly involved in lightning?
Quick Answer
Electromagnetism is most directly involved in lightning. Lightning is a giant electric discharge caused by separated charges in the atmosphere.
The Full Story
Lightning is a dramatic electromagnetic event. Inside storm clouds, collisions between ice particles separate electric charges, building up a huge potential difference between parts of a cloud or between cloud and ground. When the electric field becomes strong enough, air breaks down and a rapid discharge occurs. The resulting flash, heat, and thunder are all consequences of electromagnetism interacting with the atmosphere.
Key Facts
1.Lightning is an electric discharge
2.Air breaks down when electric fields become strong enough
3.Thunder is caused by rapid heating and expansion of air
