Oceanography Review

What causes surface currents to move in circular paths?

• strong winds
• the Coriolis effect
• salinity
• the Global Ocean Conveyor

Deep currents are caused by differences in the _______________ ocean water.

•  eutrophication of
• sun's effect on
• density of
•  salinity of 

The effect of Earth’s rotation on the direction of winds and currents is called the _______________ .

• La Niña
•  El Niño
• Coriolis effect
• Currents

Which of the following is caused by differences in ocean water density?

• surface currents
•  deep currents
• waves
• Coriolis effect

Upwelling is associated with

• a decrease in access to nutrients for phytoplankton
• cooler, nutrient-rich waters being pushed up from deeper ocean waters
• temperature gradients moving water from the equator to the poles
• an increase in human fatalities

Warm ocean currents generally come from

• The North Pole
• The South Pole
• The Equator
• Both A and B

Cold ocean currents generally come from

• The North Pole 
• The South Pole
• The Equator
• Either Pole

A measure of the amount of dissolved salts in a given amount of liquids is called: 

• salinity
• density
• deflection
• upwelling

A measure of how much mass is contained in a given unit of volume (=mass/volume) is called:

• salinity
• density
• current
• thermohaline

A movement of ocean water that follows a regular pattern is called a/an: 

• Coriolis Effect
• continental deflection
• ocean current
• global winds
