Explain how the Coriolis effect influences ocean currents.

• It causes currents to move in a straight line.

• It deflects currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• It stops the movement of currents.

• It increases the speed of currents.

Which factor is most responsible for the formation of surface ocean currents?

• Salinity differences

• Wind patterns

• Earth's magnetic field

• Underwater volcanic activity

How do ocean currents affect global climate?

• They have no effect on climate.

• They distribute heat around the planet, influencing weather patterns.

• They cause earthquakes and volcanic eruptions.

• They only affect the climate near the equator.

Using a map, identify the location of the Gulf Stream and describe its impact on the climate of Western Europe.

• The Gulf Stream is in the Pacific Ocean and cools Western Europe.

• The Gulf Stream is in the Atlantic Ocean and warms Western Europe.

• The Gulf Stream is in the Indian Ocean and has no impact on Western Europe.

• The Gulf Stream is in the Southern Ocean and cools Western Europe.

Analyze the relationship between ocean salinity and density. How does this relationship affect ocean currents?

• Higher salinity decreases density, slowing currents.

• Higher salinity increases density, driving currents.

• Salinity has no effect on density or currents.

• Lower salinity increases density, driving currents.
