Ocean Currents Review

Front

Based on the illustration, which of the following statements describes the relationship between density and temperature? Cold water is denser than warm water, Warm water is denser than cold water, Warm and cold water equal densities, The density of water is not affected by temperature

Back

Cold water is denser than warm water

Front

What two factors determine the density of water in deep currents? Options: Salinity and temperature, Coriolis Effect and wind, Upwelling and dissolved solids, Continental deflection and convection

Back

Salinity and temperature

Front

What 3 factors most directly affect surface currents in the ocean? Options: Dissolved solids, gases & energy, Upwelling, convection & sun's energy, Deep currents, convection currents & surface wind, Surface wind, Coriolis effect & continental deflection

Back

Surface wind, Coriolis effect & continental deflection

Front

Which statement accurately describes the relationships between salinity, temperature, and density of ocean water? Cold water, holding less salt, sinks towards the bottom of the ocean. Warm water, holding more salt, sinks towards the bottom of the ocean. Warm water, holding less salt, rises toward the surface of the ocean. Warm water, holding more salt, rises towards the surface of the ocean.

Back

Warm water, holding less salt, rises toward the surface of the ocean.

Front

Which of the following statements does NOT accurately describe the importance of the Gulf Stream? Options: The Gulf Stream is responsible for the mild climate of Florida., The Gulf Stream transports heat from the equator towards Western Europe., The Gulf Stream increases travel speed from southern areas to Western Europe., The Gulf Stream is responsible for removing heat from Western Europe and transferring it to equatorial countries.

Back

The Gulf Stream is responsible for removing heat from Western Europe and transferring it to equatorial countries.

Front

El Nino and La Nina are two periodic changes in ocean circulation patterns. Which of these statements best describes their effect on global climate? El Nino carries warm water, increasing rainfall along the coast of Chile, while La Nina brings cold water upwellings to western South America.

Back

El Nino carries warm water, increasing rainfall along the coast of Chile, while La Nina brings cold water upwellings to western South America.

Front

What causes the upwelling of cold water forming the El Nina weather phenomenon? Options: Weak Trade winds, Strong Ocean currents, Strong Trade winds, Weak Ocean currents

Back

Strong Trade winds

Front

El Nino causes warmer than usual Pacific ocean water temperatures off the coast of S. America (Peru). How does this impact hurricane formation in the Atlantic Ocean?

Back

Hurricane formation decreases.

Front

Which of the following is NOT a result of the warming waters in the Pacific Ocean due to El Nino? Options: Decrease amount of fish off coast of Peru, Less disease, like Malaria in Africa, Fewer Hurricanes in the Atlantic, Flooding in Australia

Back

Flooding in Australia

Front

What is the name of the warm ocean current that creates a mild climate for Florida?

Back

Gulf Stream Current
