Ch 18 Test

Which gas is most important for understanding the processes that take place in the atmosphere?

• nitrogen
• oxygen
• carbon dioxide
• water vapor

The classification of clouds is based on their

• color and form.
• density and color
• form and height
• height and density

For precipitation to form, cloud droplets must grow in volume by roughly

• one thousand times
• ten thousand times
• one million times
• one hundred thousand times

What does the Bergeron process explain?

• formation of clouds
• movement of air masses at fronts
• growth of ice crystals in clouds from supercooled water
• change of water from the solid state directly to the gaseous state

The precipitation that forms in a cumulonimbus cloud when small ice pellets fall through it and grow by collecting supercooled water is

• rain
• snow
• sleet
• hail
