Ocean Currents Review

Streamlike movements of water that occur at or near the surface of the ocean are called

• jet currents.
• Coriolis currents.
• surface currents.
• deep currents

Which of the following pushes surface currents and forces them to move?

• global winds

• thermohaline

• changes in density

• None of these

The Coriolis Effect is caused by

• Earth rotating on its axis
• The tides
• Gravity

Upwelling is

• 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

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

• La Niña
•  El Niño
• Coriolis effect
• Currents

What three factors work together to form a pattern of surface currents on Earth?

• weather, wind, sun
• global winds, the Coriolis effect, continental deflections
• global winds, the Coriolis effect, sun
