100
What percentage of all the water on Earth is freshwater?
3%
100
What percentage of the hydrosphere (ALL water on Earth) is contained in the oceans (Saltwater)?
97 percent
100
What is the gently sloping area of sediments that sits at the base of the continental slope?
continental rise
100
A place where groundwater is stored
aquifer
100
A body a water above ground. Water is stored here
collection
100
These are most commonly caused by wind that blows across the surface of the water. This transfer of energy passes through the water, and forces it to move in a circular motion.
(It is seen on the surface as an up and down movement of water).
a wave
200
Process that changes liquid water to a gas
Evaporation
200
What process is the change of water vapor to a liquid
condensation
200
What is the name of the flat, level area that covers most of the deep ocean floor?
abyssal plain
200
percentage of freshwater available for human use.
less than 1%
200
The source of energy for evaporation and the main energy source in the water cycle
The sun.
200
Where is most of Earth's fresh water found
Glaciers/ice
300
What process acts as a "recycling system" for the ocean floor, destroying old crust at trenches?
subduction
300
In a closed system, the total amount of water on Earth stays constant. what 2 processes in the water cycle must be equal
evaporation and precipitation
300
A "river" of water moving through the ocean
current
300
Deep currents are created by this
Differences in density
300
The process where plants take in water through their roots, and give off water vapor through their leaves
transpiration
300
The students in 6th grade are testing water at different temperatures to measure density. One group gets cold fresh water, one group gets warm fresh water, one group gets cold saltwater and the last group gets warm saltwater. Based on the properties of Earth’s water, which group will have the water with the most density?
A cold saltwater
B cold freshwater
C warm freshwater
D warm saltwater
Cold Saltwater
400
Surface currents affect the climate of the coastal area they pass by. This surface current is warm and affects the climate of the Eastern coast of the United States
The Gulf Stream
400
At a subduction zone, what specific topographic feature is formed when one plate sinks?
deep ocean/sea trench
400
triangular deposit, usually made up of silt and clay particles, that forms where a stream enters a large body of water
delta
400
An underwater volcanic mountain with a flat top (usually due to erosion).
guyot
400
The most abundant salts in the ocean
sodium and chloride
400
Tides are caused mainly by the ______________
When we have a spring tide, the sun, earth and moon are ________________
When we have a neap tide, the sun, earth and moon are______________
gravitational pull of the moon
straight line (180 degrees)
right angle (90 degrees)
500
The curving of surface currents and global winds, caused by Earth's rotation.
Due to this curving, Surface currents form large circular patterns that flow clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.
The Coriolis Effect
500
what is the average salinity of the ocean
3.5% or 35ppm
500
Water flowing down slope along Earth's surface that may reach a body of water, may evaporate or may accumulate as puddles in low-lying areas and eventually seep into the ground
runoff
500
The original location of a current transporting water affects the current's t_________________e
temperature
500
What effect does increase salinity have on ocean water density? AND what 2 process increases salinty?
Increased salts = increased density
Evaporation and Freezing
500
Which feature drops off sharply from the edge of a continent?
Continental slope
600
In the ocean, pressure and density ___________ with depth while temperature___________ with depth.
Increases, decreases.
600
If we had a spring tide on May 14, when will we have a neap tide.
May 21st
600
What is the midocean ridge and what is seafloor spreading
an under water mountain range (longest in the world).
When oceanic plates constantly pull away from each other causing magma to erupts creating new crust/seafloor
600
If global glaciers melt rapidly, what happens to the overall salinity of the ocean?
decreases
600
This diagram is showing the water cycle process of ___________________
Infiltration

The dew point is the temperature the air has to reach for condensation to take place.
When rising air reaches dew point, what forms in the sky?
Clouds
700
Once the water vapor ___________, it is changed from a gas to a liquid and forms clouds, fog or dew
condenses
700
Which factor is most responsible for the movement of water down through an aquifer’s layers?
