The weather is not beautiful all of the time. Perhaps you can remember a day when bad weather made you afraid. One kind of bad weather that scares many people is called a thunderstorm. This is what happens when there is a thunderstorm. First, you see a sudden flash of bright light. A few seconds later 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 moving very rapidly. It may be moving between a cloud and the ground, between two clouds, or between two parts of the same cloud. The lightning heats the air around it. This hot air expands, or get bigger, and it causes 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.

____ 29/ Lightning may move between a cloud and the ground.

____ 30/ Thunder is a very bright light in a thunderstorm.

____ 31/ When you hear thunder you may hear a series of loud sounds and not one

big sound. This is because the air waves pass one after another.
