7. Lightning is Slow Motion Video

8. Lightning Formation During a storm atoms in clouds bump together and their charges separate A negative charge forms at the bottom of the cloud

9. How Lightning Works The negative electrical charge at the bottom of a cloud creates a positive charge in the ground below. WHY?

10. How Lightning Works As the negative charge get stronger, the air cannot stop it from jumping from the cloud towards the positive charge on the ground. The giant spark of electricity is the lightning that we see.
