ClOUDS VOCABULARY

• humidity the amount of water vapor in the air
• dew point the temperature at which
  condensations begins
• dew moisture that forms on the ground
• fog clouds that form near or on the ground

3
WATER CYCLE CLOUDS

• First, water evaporates
• Then water in the atmosphere begins to condense
  to form clouds
• Some clouds will eventually precipitate

4
HOW DO CLOUDS FORM?

• Clouds form when water vapor in the air becomes
  liquid water or ice crystals.
• Water condenses on small particles or dust
  suspended in the air to form a cloud

• Stratus layered are wider than they are
  tall
• Cirrus wispy feathered clouds

Precipitation

• Precipitation is any form of water that falls
  from clouds.
• Droplets must grow heavy enough for rain or snow
  to fall from the clouds

15
Types of Precipitation

• rain water that is at least above 0C
• sleet rain falls then freezes before it hits
  the ground
• freezing rain rain that falls then freezes
  after it hits the ground
• hail round ice pellets from cumulonimbus clouds
• snow water vapor forms snow inside a cloud
