The Earth System Chapter 2

How does evaporation contribute to the water cycle?

• Water turns into gas and rises into the air
• Water vapor cools and turns into liquid droplets, forming clouds
• Rainwater sinks into the ground
• Ice melts into liquid water

Which choice best describes how water vapor molecules move in the atmosphere during evaporation?

• Water vapor molecules sink into the ground
• The molecules immediately turn into raindrops
• The molecules rise into the air atmosphere
• Water vapor molecules do not move

How does water vapor affect the weather?

• It has no impact on the weather
• It helps form clouds and precipitation
• It prevents the sun from warming the Earth
• Water vapor makes the wind blow harder

What happens during condensation?

• Liquid water freezes to form ice
• Rainwater will seep into the ground
• Water vapor cools and turns into liquid droplets, forming clouds
• Water vapor molecules rise

How does the water cycle show that the water is reused over and over?

• Once water is used by a plant or animal, it is never returned.
• New water is made every time it rains
• Water evaporates and is stored in the clouds forever
• The same water evaporates, condenses. and falls as precipitation in a continuous cycle

What role can evaporation play in making a Freshwater Solution?

• It has no effect on freshwater
• It removes the water vapor, leaving dissolved salt behind
• It creates new water molecules from the air
• Water freezes and turns into ice

How do raindrops form?

• Raindrops form when the sun heats up the ocean and creates bubbles.
• Raindrops form from solid ice crystals melting in the air.
• Raindrops form when water vapor condenses into droplets in the atmosphere.
• Raindrops are created when clouds burst and release water.
