A scientist wants to track contaminant movement in the Gulf Stream. The Gulf Stream is a warm water current in the North Atlantic Ocean and is part of the North Atlantic gyre. The gyre is influenced by the Coriolis effect. To follow the contaminant after it exits the Gulf Stream, the scientist needs to know characteristics of the North Atlantic gyre. Which of these best describes a movement of the North Atlantic gyre the scientist needs to know?
linear movement due south
linear movement due west
counterclockwise movement
clockwise movement
No water movement
Which of the following air movements are not cyclonic?
typhoon
tornado
drought
hurricane
Which statement best explains the role of evaporation in ocean currents?
Evaporation increases the air pressure above surface waters, causing horizontal currents.
Evaporation adds salt to surface waters, forcing the water to sink.
Evaporation removes heat energy from surface waters, increasing the water density.
Evaporation leads to the movement of air masses, causing surface currents.
Which direction do currents run in the NORTHERN hemisphere?
Counterclockwise
Clockwise
Which direction do currents run in the SOUTHERN hemisphere?
Counterclockwise
Clockwise
Which factors affect global ocean currents?
temperature, glacial ice melt, salinity
Density, buoyancy, sediment
Waves, temperature, wind
