Perhaps you can remember a day when bad weathermade you afraid. One kind of bad weather that scares many people is called a thunderstorm. This iswhat happens when there is a thunderstorm. First you see a sudden flash of bright light. A few secondslater you hear a loud rumbling sound. This quick flash is called lightning, and the loud sound is called thunder. Lightning is colorful, but it can cause serious problems. Lightning is electricity that is movingvery rapidly. It may be moving between a cloud and the ground, between two clouds, or between twoparts of the same cloud. The lightning heats the air around it. This hot air expands, or gets bigger, and itcauses the air to move in waves. The air waves pass you in a series, one after another. For this reason,you may hear many rumbles and not just one sound.
