|
How does lightning form?
|
Inside a thundercloud lightweight positive ice particles rub together at the top of the cloud. Heavy negative water particles settle at the bottom of the cloud and keeps building. Soon the buildup is so much that charges jump between the cloud and the ground as a discharge. A giant spark of lightning results.
