What happens when the atmosphere becomes saturated with water vapor?

• Water vapor turns into steam
• Water vapor freezes into ice crystals
• Water vapor evaporates into the atmosphere
• Water vapor condenses back into liquid water

How does temperature affect the rate of evaporation?

• Higher temperatures increase the rate of evaporation
• Lower temperatures increase the rate of evaporation
• Temperature has no effect on the rate of evaporation
• Higher temperatures decrease the rate of evaporation

What is the dew point?

• The temperature at which water boils
• The point at which the atmosphere becomes saturated with water vapor
• The point at which water evaporates
• The temperature at which water freezes

What is the process by which liquid water changes to gaseous water vapor in the air?

• Condensation
• Boiling
• Freezing
• Evaporation

What is the role of water in the water cycle?

• To change state from liquid to gas
• To regulate temperature
• To provide drinking water
