Section 1 B Water in the Air Clouds

a collection of millions of tiny water droplets or ice crystals cloud

Clouds form as water vapor is warm added to the air and ______ rises and cools.

As it cools, the air becomes _____ saturated and changes to a liquid or solid due to condensation ______.

flat-bottomed, puffy, white cloud cumulus

The prefix nimbo- or the suffix -nimbus added to the name of a cloud indicates the probability of _____. precipitation

cloud that produces thunderstorms cumulonimbus

clouds that form in layers, caused by a gentle lifting of a large body of air into the atmosphere stratus

a cloud that produces light to heavy continuous rain nimbostratus

stratus cloud formed when water vapor condenses near the ground fog

thin, feathery clouds found at high altitudes cirrus

the prefix used to describe high-altitude clouds cirro-

the prefix used to describe middle-altitude clouds alto-

the prefix used to describe low-altitude clouds strato-

Types of Clouds
