What Causes Lightning?

Clouds are like giant batteries that can store electricity, and when they get full, lightning happens, it's like a big spark jumping from one place to another.

Inside a cloud, tiny bits of ice and water bump into each other. It’s like when you shake up a bottle of fizzy drink, all that jiggling makes little charges move around. Some parts of the cloud get positive charges, and others get negative charges.

When the difference between those charges becomes too big, it's like a rubber band snapping, snap! A lightning bolt jumps from the cloud to the ground (or another cloud), making a bright flash and a loud thunderclap. It’s like when you touch a doorknob after walking on carpet in socks, zzzt!, but way bigger!

Sometimes, lightning even zips through the air between clouds or goes all the way from one cloud to another. It's just the electricity looking for a path to balance things out!
