The Water Cycle

During what part of the water cycle does water vapor turn into liquid droplets?

• evaporation

• condensation

• precipitation

• run off

What must happen to water vapor in order for it to turn into liquid droplets?

• It must be heated.

• It must be cooled.

• It must remain the same temperature.

• It must be pushed by wind.

A cold, closed bottle of water is left in the sun. Water forms on the outside of the bottle. This is an example of

• evaporation

• precipitation

• water vapor

• condensation

The class created models of the water cycle in plastic bags. Which would represent the precipitation stage of the water cycle?

• The amount of water in the cup.

• The water vapor at the top of the bag.

• The amount of sunlight heating the water.

• The water droplets running down the side of the bag.

What is the water cycle?

• the 3 forms of water

• the movement of water on, above, or below the surface of the Earth

• when water melts

• when clouds form

What is the energy source for the water cycle?

• the sun

• the earth

• water

• the moon

What is evaporation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.

• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.

• The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.
