Ch. 17 Moisture, Clouds, And Precipitation

The cloud form that is best described as sheets or layers that cover much or all of the sky is termed

The cloud form that consists of globular cloud masses that take o a billowy or "cauliflower-like" structure is called

This term is used to describe clouds founding the middle height range

High clouds that form delicate veil-like patches o extended wispy fibers are termed

This term is used to describe clouds that produce precipitation

These clouds are often called "fair weather" clouds

This cloud sometimes produces "mare's tails"

Thunder and lightning are associated with these clouds

This cloud type is confined to the middle height range

A halo around the Sun or Moon indicates that this cloud type is present

A dark gray cloud that blankets the sky and often generates precipitation is called

This cloud may develop an "anvil head"

Tornadoes can be associated with this cloud type

Hail is most commonly associated with

A wintertime form of precipitation that consists of small ice particles is called

Deserts such as the Great Basin, Gobi, and Takla Makan are examples of

The change of state from a gas to a liquid is called

The term ______ is used to describe the conversion of a solid directly to gas, without passing through the liquid state.

The process by which water vapor changes directly to a solid is called

This process results in the release of about 600 calories of latent heat per gram of water.

The process of converting a liquid to vapor is termed
