Why clouds are not falling down?
Clouds can hold an enormous amount of water. When this water falls as rain it clearly has a significant mass so why don’t clouds fall? In fact, the small water droplets that make up clouds do fall slowly. However, the drag force of the air dominates over the gravitational force for small particles.
Why do clouds look fluffy?
When the water vapor meets the cold air found high in the sky, the gas condenses to liquid and forms cumulus clouds. While these fluffy-white clouds look like soft pillows of cotton, they are actually composed of small water droplets.
