The Water Cycle (Hydrologic Cycle)

As water vapor rises in the atmosphere it can turn into water droplets or ice crystals which results in cloud formation.

• precipitation
• condensation
• ground water
• surface water runoff 

When water vapor condenses directly onto a surface __________________  occurs. 

• condensation
• dew
• rain
• frost

Water continually cycles between the atmosphere (troposphere), land, and ocean via the water cycle.  These processes are propelled by sunlight and gravity.

• precipitation
• condensation
• water cycle (hydrologic cycle)
• surface run off

This is the process of the formation of large crystals in a pure state from a mixture (i.e. rain and salt). 

• crystallization
• dew
• precipitation
• transpiration

Forms of water falling from the sky as rain, sleet, hail, and snow. 

• condensation
• transpiration
• precipitation  
• surface run off

This forms when water vapor changes from gas directly to ice crystals on a surface when the temperature at which condensing would take place are at the freezing point or below.

• dew
• rain
• snow
• frost

This occurs when heat is added, water turns into a gas. 

• condensation
• evaporation
• transpiration
• crystallization

When water enters the atmosphere as water vapor through the release of water vapor from plants' leaves.                

• evaporation
• transpiration                                      
• condensation
• ground water

Water that flows beneath the Earth's surface.                          

• groundwater flow                            
• precipitation
• surface water flow
• flood 

Heat helps water form into a gas.
