What causes thunder and lightning? | Thunderstorm | Video for Kids?

Thunder and lightning happen when clouds fight a big electric battle up in the sky.

Imagine you're playing with your friend on a slide, one of you goes down fast, and the other stays at the top. That’s like what happens inside a cloud: tiny bits called water droplets and ice particles are sliding past each other really fast. This sliding makes something called electricity, which builds up in the cloud.

When the electricity gets so strong that it can’t stay in one place, zap, it jumps to another cloud or even to the ground! That’s lightning!

Now imagine you're shouting across a big room, your voice makes the air around you wiggle. Lightning works the same way. When lightning flashes, it makes the air wiggle really fast, and that wiggle is what we hear as thunder.

So next time you hear thunder and see lightning, just know: it's like a big electric slide party in the sky!
