What Are Clouds Made Of?
1. Water
Most clouds in Earths skies are made from water. It gets there through evaporation as the heat from the sun heats up the water on the surface. When it reaches a certain height, the water condenses and, under the right conditions, it will remain suspended in the air. For a while at least. When the conditions are right, you can sometimes see clouds expanding in size. Take a distant storm cloud in its infancy, for example, and you will see the cloud get visibly larger as more water rises and then condenses. While the sight of clouds can ruin the day for a lot of people, it can also be a blessing for many others.
