1. Clouds

2. How Do Clouds Form? Warm air rises and cools
As the rising air cools, it becomes saturated (because cool air can’t hold as much water vapor)‏
When the air is saturated, the water vapor changes to a liquid or a solid, depending on temperature

3. Cumulus Clouds
Cumulus clouds are white, puffy clouds, usually with flat bottoms

4. Stratus Clouds Stratus clouds are clouds that form in layers.
Stratus clouds cover large area of the sky and often block out the sun.
They are caused by a gentle lifting of a large body of air
Fog is a stratus cloud that forms near the ground

5. Cirrus Clouds
Cirrus clouds are thin, feathery white clouds found at high altitudes
Cirrus clouds form when the wind is strong

6. Cloud names
Scientists attach prefixes and suffixes to cloud names to tell more about them
Attaching -nimbus or nimbo- to a cloud name means that cloud is likely to produce precipitation.
Attaching cirro- to a cloud name means it forms at a high altitude.
Attaching alto- to a cloud name means it forms at a middle altitude.
