Meteorology Ch. 5 - Clouds

This type of cloud is thin, wispy, and made of ice crystals (considered a high level cloud).

• cumulus cloud

• stratus cloud

• cirrus cloud

• cumulonimbus cloud

The temperature at which water vapor condenses is the 

• relative humidity
• humidity
• freezing point
• dew point

This type of cloud is thick and puffy on top, and generally flat on the bottom. It has well-defined edges and can change shape rapidly.

• cumulus cloud
• stratus cloud
• cirrus cloud
• cloud 9

Why doesn't cloud formation take place until the dew-point temperature is reached?

• because dew-point is the temperature at which water vapor condenses into water droplets
• cloud formation can take place at any temperature, and does not depend on the dew-point temerature
• because water sublimates at the dew-point temperature
• the dew-point temperature only applies on Earth's surface, not in the atmosphere
