30s - Q2
What factors create deep ocean currents?
Increase in salinity; decrease in temperature
Increase in salinity; increase in temperature
Decrease in salinity; decrease in temperature
Decrease in salinity; increase in temperature
30s - Q3
Streamlike movements of water at or near the surface of the ocean are called ____.
Jet Stream Currents
Convection Currents
Deep Ocean Currents
Surface Currents
30s - Q4
The Coriolis effect causes ___________.
global winds and surface currents to move in a curved path instead of a straight line
the Earth to rotate on its axis
global winds and deep ocean currents to move in a curved path instead of a straight line.
continental deflection
30s - Q5
What does the Coriolis effect have on surface currents in the northern and southern hemispheres?
in general, surface currents will flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.
in general, there is no real effect
in general, they flow in the same direction
in general, surface currents will flow counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
30s - Q6
What happens when an ocean current meets a land mass?
a tidal bore forms
the water heats up
an undertow recedes from the shoreline
the current is deflected
30s - Q7
Explain the role of density in the movement of deep currents.
Cold, high salinity deep current water is more dense than warm, low salinity surface current water. As warm water rises, cold water will move in to take its place, creating a circular movement called a convection current.
Cold, high salinity deep current water is less dense than warm, low salinity surface current water. As warm water sinks, cold water will move in to take its place, creating a circular movement called a convection current.
30s - Q8
The amount of matter in a given space is called ___.
mass
density
pressure
volume
30s - Q9
If a cool surface current flows along a coastline, what effect might it have on the climate in that area?
In general, it will bring cooler temperatures in the summer and milder temperatures in the winters
In general, it will have no long term effect on climate in that area.
In general, it will bring cooler temperatures in the summer and colder temperatures in the winters
In general, it will bring warmer temperatures in the summer and milder temperatures in the winters
30s - Q10
Where on Earth does the Sun's energy heat up the ocean water the LEAST?
near the continents
at the Poles
at the equator
the Sun's energy heats up ocean water the same all around the Earth
30s - Q11
Due to the jet stream, weather in Northern hemisphere blows ---- to ----- .
south; north
east; west
north; south
west; east
30s - Q12
What is the initial source for global winds and convection in the atmosphere?
The rotation of the Earth
continental deflection
Unequal heating of the Earth by the sun.
Moon's gravity
30s - Q13
If a liquid has a mass of 20 g and a volume of 4 mL, what is the density of the liquid?
5 mL/g
4 g/ mL
5 g/ mL
4 mL/ g
30s - Q14
Describe convection.
the transfer of heat energy across open space
the transfer of heat energy by direct contact
the transfer of heat energy by movement of water or air in a circular motion
30s - Q15
Which of the following is NOT a way to increase density of water?
evaporation of water
Decreasing the temperature of water
Increasing the temperature of water
freezing of water
