1.
What is condensation?
a)

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.

b)

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

c)

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.

2.
What is evaporation?
a)

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.

b)

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.

c)

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.

3.
Snow, sleet, hail, and rain are all examples of  ________________. 
a)

evaporation

b)

condensation

c)

accumulation

d)

precipitation

4.
On which kind of day would you expect the most evaporation from the surface of a pond?
a)
cold, rainy
b)
cold, sunny
c)
warm, rainy
d)
warm, sunny
5.

What is water vapor (a gas) doing when it changes to liquid water?

a)

evaporating

b)

condensing

c)

precipitating

d)

runoff

6.
What is the water cycle?
a)

the 3 forms of water

b)

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

c)

when water melts

d)

when clouds form

7.
Water on Earth moves through the water cycle because of energy that comes from the --
a)

Earth's core

b)

Sun's heat

c)

Moon's gravity

8.
How will the Sun’s energy affect the ocean, rivers, and lakes? 
a)

The ocean water will increase due to the runoff of the rivers. 

b)

The rivers and lakes will increase because of more precipitation

c)

Heat from the Sun will cause liquid water to condense and form water vapor. 

d)

Heat from the Sun will cause liquid water to evaporate and form water vapor. 

9.
What is it called when plants give off water vapor as a waste product?
a)

condensation

b)

evaporation

c)

sublimation

d)

transpiration

10.
