Why are clouds white? �Clouds reflect the light of the sun. � Light is made up of colors of the rainbow and when you add them together you get white.

Why do clouds turn gray? �Clouds are made of tiny water droplets or ice crystals! �If the clouds are thick or high enough, all the light does not make it through, making the cloud gray or dark.

How do clouds form? �All air contains water but near the ground it is in the form of an invisible gas called water vapor. �Some of the water vapor becomes tiny pieces of dust that float around in the air. � When billons of these droplets come together they form a cloud.

To make a cloud you need 3 things: �Water vapor (moisture) to build a cloud �Cooling Air for water vapor to condense �Dust particles where condensation can form water droplets. �Now, cup your hands around your mouth and exhale into your hand. (warm and moist like a cloud)
