Irrigation is used to supply water for

Agriculture (or farming) A 100

Making paper is an example of using water for

Industry (or manufacturing) A 200

Many large cities are located on rivers or coasts because people use water for

transportation A 300

Plants use water, CO2, and energy from the sun to make food during this process

photosynthesis A 400

Water that fills the cracks and spaces in underground soil and rock layers

groundwater A 500

The gaseous form of water is called B 100

water vapor B 100

A mixture that forms when one substance dissolves another is called

solution B 200

Tightness across the surface of water that is caused by polar molecules pulling on each other is called B 300

surface tension B 300

Water that falls to Earth as rain, snow, sleet, or hail is called B 400

precipitation B 400

The process by which plants release water into the air is called B 500

transpiration B 500

A water molecule is made up of C 100

Two hydrogen atoms bonded to an oxygen atom C 100

Water is a “polar molecule” that means

have a charge (or regions that are slightly + or -) It has areas that have a charge (or regions that are slightly + or -) C 200

This water strider can walk on the water because of this property

Surface Tension C 300

The petals of these flowers absorb the colored dye because of what process

Capillary Action C 400

Because water can dissolve so many substances it is called

Universal Solvent C 500

The process by which a gas changes into a liquid is called

condensation D 100

When water evaporates, it becomes a D 200

Gas (or vapor) D 200

When a solid becomes a liquid it is called

melting D 300

When a liquid becomes a solid it is called

freezing D 400

When a solid changes into a gas without becoming a liquid, it is called

sublimation D 500

The energy for the water cycle originally comes from the

Sun E 100

When water evaporates from the oceans, it becomes fresh water, leaving what behind?

Salt E 200

As water vapor rises up into the atmosphere what happens?

(condenses, loses energy, becomes a cloud) It cools off or (condenses, loses energy, becomes a cloud) E 300

Why does the total amount of Earth’s waters stay the same

The total amount of evaporation equals the amount of precipitation

If a molecule of liquid water evaporates into water vapor, what happens to the energy of its particles E 500

The particles gain energy or (move faster, increase)

In what form is most of Earth’s fresh water found?

Ice (or solid water) F 100

This percentage of Earth’s total water is fresh

3 percent F 200

In this step water becomes a gas F 300

C (evaporation) F 300

This part of the Earth’s surface is where most evaporation occurs and precipitation falls

B (ocean) F 400

What 2 steps involve a change of state?

C (evaporation) liquid to gas and D (condensation) gas to liquid F 500

The Final Jeopardy Category is: Why Ice Floats Click on screen to begin

Click on screen to continue Ice floats on liquid water because it is less dense. What changes when water freezes that makes it less dense? Click on screen to continue

Click on screen to continue Ice molecules take up more space when they freeze (or its volume increases, ice expands when it freezes) Click on screen to continue
