Question

Which of the following best explains why lightning occurs? (Sorry about the subject, physics does not seem to have any people answering questions for it)

A: The warm updraft heats air molecules to extreme temp
B: Positive and Negative ions build up and need to discharge
C: High pressure storms condense air into a high energy state
D: Thunderstorms pull energy up from earth to sustain themselves

Answer 1

b Is your answer

Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. ... This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash

Hope this helps :p

I hope b is the answer :/
