Question of the day

Nature
What causes thunder and lightning?
Thunder and lightning happen when there is a big storm in the sky. Lightning is a big spark of electricity that jumps from one cloud to another, or from a cloud to the ground. Thunder is the sound that lightning makes when it heats up the air. It's like a big clap or boom that we can hear. So when you see lightning, count how many seconds it takes for the thunder to follow. That can tell you how far away the storm is!
