Two explanations that provide the best reasoning for why clouds are an example of matter but thunder is not:
Clouds are fluffy and do not have any real mass.
Clouds are made of water and have mass.
Thunder takes up space inside of clouds.
Thunder is sound, which is a form of energy that does not take up space.
