Did you ever think about why clouds are white or what they're made of? Clouds are not just fluffy cotton balls floating in the sky. They are made of tiny water droplets or ice particles. But, they appear white because they reflect all the colors of the sunlight equally. There are different types of clouds too. Cumulus clouds are big and fluffy, stratus clouds are like a thick blanket, and cirrus clouds are thin and wispy. Cirrus clouds can sometimes even tell us that rain might be on its way! So, next time you see a cloud, can you tell what type it is?
