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 

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

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

• salinity
• density
• deflection
• upwelling

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

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

How do salinity and temperature affect the density of ocean water?

• salinity increase = density increase, temp decrease = density increase
• salinity decrease = density increase, temp. decrease = density decrease
• salinity increase = density increase, temp increase = density increase
• salinity decrease = density increase, temp increase = density increase 

____________ tides are typically weaker tides.

• Spring

• Neap

• Neither

• Both can be equally strong

Tides are created by the interactions between

• earth and moon

• earth, moon and sun

• earth and sun

• earth's rotation

Estuaries are____________________.

• where 2 different oceans mix

• where fresh and salt water mix

• deep sea vents

• another name for guyots
