WATER CYCLE

REVIEW Lessons 2.01 - 2.02

Multiple Choice

1. Where does the water cycle get energy to move water through the cycle?

Multiple Choice

2. How does the sun impact evaporation?

• The sun heats the ice in clouds to form rain or snow.

• The sun forms bonds that bring the water molecules back into liquid form.

• The sun breaks the bonds that hold liquid water's molecules together.

Multiple Select

3. Select all of the ways collection areas use to gain water.

• runoff from precipitation

• precipitation falls direction into the collection area

• water evaporates from the collection area

Multiple Choice

4. Which one of these is not a human effect on the water cycle?

• Developed areas prevent soil from absorbing rainwater

• Storm water runoff carries pollution

• Air pollutants wash onto land and water bodies from precipitation

• Precipitation is increasing in deserts due to an increase in water use

Fill in the Blank

5. Enlarge the graph. How much water on Earth is freshwater? (You can type % or leave it off)

Groundwater

Review Lesson 2.03

Multiple Choice

6. An aquifer is ground water.

• true

• false

Multiple Choice

7. Groundwater can be found in soil and rock particles

• true

• false

Multiple Choice

8. Groundwater is found in oceans

• true

• false

Multiple Choice

9. Select the word that means how easily water can move through a substance.

• sediment

• permeability

• particles

• porosity

Multiple Choice

10. Amounts of space in between the particles of two different soil samples

• porosity

• permeability

• particulate

Watershed

Review Lesson 2.03-2.04

Multiple Choice

11. I live in a watershed.

• true

• false

Multiple Choice

12. What is the name for the land area where all rain runs downhill to a certain point?

• collection

• ocean

• estuary

• watershed

Multiple Choice

13. What is an aquifer?

• type of surface water

• natural underground storage area

• precipitation that soaks through the surface soil

• pore space in the rock and soil layer beneath our feet

Multiple Choice

14. Why are watersheds important for the maintenance of water quality?

• they can transfer pollutants or filter them through the soil

• they cause precipitation and acid rain

• they can trap water in a parking lot

• they cause floods

Salinity, Density, Temperature

Review Lessons 2.05-2.08

Multiple Choice

15. What is salinity?

• The concentration of dissolved salt in any liquid

• to become incorporated with a liquid in forming a solution

• a liquid mixture in which the smaller component (solute) is distributed evenly through the major component (solvent)

• the total amount of sodium dissolved in the ocean

Multiple Choice

16. What is density?

• the amount of salt in water

• the weight of water

• a measure of salinity

• the amount of molecules in a specific volume (space)

Multiple Choice

17. What does evaporation do to salinity in the ocean water?

• water molecules (H20) absorb energy

• where there are higher levels of water evaporation, the water has greater salinity

• warmer water molecules move farther apart

• evaporation does not impact salinity

Multiple Choice

18. During the summer months, glaciers at the poles melt, delivering fresh water to the ocean. What does this do to salinity?

• it does not change the salinity

• raises salinity

• lowers salinity

Multiple Choice

19. What happens to ocean water temperatures as you go deeper under the ocean?

• the temperatures increase

• the temperatures drop

• the temperatures do not change

Multiple Choice

20. As the amount of salt in water increases, the___________ of the water increases.

• temperature

• density

• size

• humidity

Multiple Choice

21. Deep, cold water is the __________.

Warm, shallow water is the ___________.

• least dense; least dense

• densest; least dense

• least dense; densest

• densest; densest

Wind

Quick Review Question

Multiple Choice

22. What causes Earth’s major wind patterns?

• The density of ocean water changed wind patterns

• The latitudes of different areas

• The Earth is spinning

• Radiant energy from the sun strikes Earth unevenly.

Surface Water

Review Lesson 2.09

Multiple Choice

23. What is the main cause of surface ocean water circulation (movement)?

• density

• temperature

• winds

• salinity

Waves

Review Lesson 2.13

Multiple Choice

24. How do water particles in an ocean wave move?

• in a circular motion

• up and down

• back and forth

• from one side to the other

Multiple Choice

25. How are ocean waves formed?

• energy transfer

• convection

• conduction

• gravity

Multiple Choice

26. The waves' energy runs through water molecules, but they do not move the water molecules in the direction of the waves.

• True

• False
