100
This occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
Transpiration
100
The 2nd layer of the ocean is called the _______.
Transition Zone
100
As salinity increases, density ________.
Increases
100
Surface Currents are caused by ______.
Wind
200
About how much freshwater is available to drink and easily accessible to humans?
1%
200
What is the power source of the water cycle?
The sun
200
Feature A is called _______.
Continental Slope
200
Which sample of water would have the HIGHEST density? Why?
A) warm, tropical ocean water
B) cold, artic water
B) cold, artic water. When water molecules are "cold" they get close together and move slowly, resulting in a higher density.
200
A(n) ______ in the distance the wind blows will increase the height of a wave.
increase
300
Where is most of Earth's freshwater found?
Ice caps/Glaciers
300
The ice cubes play what role in this model of the water cycle?
Condensation: The ice provides the colder temperature required for water vapor to CONDENSE back into liquid.
300
Deep currents are caused by differences in ______.
Density
300
The most abundant type of salt in the ocean is _______.
Sodium Chloride (NaCl)
300
When the Sun, Moon and Earth are in a straight line, this creates a __________
.
Spring Tide
400
True or False: Rivers provide more freshwater to humans than lakes.
False. Lakes make up 87% of available surface water whereas rivers only make up 2%.
400
The process of water seeping into the ground is called _________.
Infiltration
400
Feature D is called _______.
Mid Ocean Ridge
400
Name TWO ways that salinity can change.
1) Evaporation
2) Ice melting
3) river dumping into oceans
400
The spinning of winds and ocean currents because of earth's rotation is called the __________.
Coriolis Effect
500
Where on Earth does the most evaporation take place?
The Ocean
500

500
True or False: Feature E is a Sea mount.
False: Feature B is a sea mount. E is a volcanic island.
500
What body of water has the highest salinity in the world?
The Dead Sea
500
Tides are caused by the _________ of the sun and the moon.
Gravitational Pull
