When the air rises up in the atmosphere, gets cooler and condenses, there are droplets that form and are suspended in the air. These different size droplets help to form clouds. Small droplets will sometimes make a white cloud.
The bigger droplets gather more of the sun’s rays and they make clouds that are darker and sometimes even the color grey. Droplets that are super large, can make clouds look like they are black. These droplets are so big that they can fall through the cloud and into the air. This is called rain.
Clouds that look flat, look this way because the temperature of the air causes the air to get humid. When the humidity reaches 100%, it causes the clouds to form and look like they have flat bottoms.
There are three classifications of clouds. These classifications are based on what shape the clouds are. The tree different types are cirrus, stratus and cumulus.
Cumulus clouds are called storm clouds or thunderclouds.
Clouds that are seen at low levels and that have layering are stratus clouds. These types of clouds are sometimes called hazy or clouds that do not have any features. Most of these clouds are either white or dark gray.
When clouds are feathery looking and look thin, they are cirrus clouds. Cirrus clouds only form when they are high in the air and they are made up of crystals of ice.
When stratus or cumulus clouds are higher in the altitude than normal, they are called alto clouds. That means one could be an altocumulus or an altostratus cloud, depending on where they are at in the air.
Clouds that are middle clouds are called alto clouds and they usually are developed in the middle of the troposphere which is 1-4 miles above the surface of the earth.
All clouds are formed from water droplets. Even though all clouds are formed from water droplets, not all clouds cause rain. The cloud has to have super heavy droplets in order for there to be rain from the clouds.
