Water Cycle

During which stage do clouds form?

• condensation
• evaporation
• precipitation

Which stages does liquid water from the ocean turn into water vapor?

• condesantion
• evaporation
• precipitation
• run off

What is it called when plants give off water vapor as a waste product?

• condensation
• evaporation
• sublimation
• transpiration

What drives evaporation and transpiration?

• the sun
• gravity
• cooling

What is the process during which water cools and turns from a gas to a liquid?

• Codensation
• Runoff
• Precipitation
• Evaporation

In which way are evaporation and condensation similar?

• A. Both cause decreases in air temperature.
• B. Both cause increases in air temperature.
• C. Both are caused by the warming of the atmosphere.
• D. Both are caused by changes in heat energy.

After Todd took a hot shower, he noticed that the bathroom mirror looked foggy. He could not see his reflection. Which statement best explains what happened?

• A Water froze on the mirror because its surface was cold.
• B Hot water splashed on the mirror and heated its surface.
• C Water evaporated when it touched the hot mirror’s surface
• D Water vapor condensed when it touched the cold mirror’s surface.

This photograph shows a beach on a partly sunny day. 
 Which of the following is an interaction between the sun and the ocean that results in clouds forming near the beach? 

• A.  Energy from the sun causes precipitation over the ocean.
• B.  Energy from the sun causes water to evaporate from the ocean.
• C.  Light from the sun reflects off the surface of the ocean.
• D.  Light from the sun decreases the amount of water vapor in the air over the ocean.

What happens to the water that does not fall into oceans or other water sources when it rains?

• A.  The water instantly evaporates.
• B.  The water sinks into the ground to form ground water.
• C.  The water stays in puddles forever.
• D.  All water which does not land in oceans falls in lakes, rivers, and ponds.

9. Students are exploring how water changes state in the water cycle through evaporation, condensation, and precipitation.  They notice that the sun heats the ocean, changing into a gas.  It then enters the atmosphere where the temperature decreases and it changes back into a liquid.  Based on the information given, the students are making –

• A.  a hypothesis
• B.  a prediction
• C.  an observation
• D.  a data table
