Ocean Circulation

Question 1

Which statements describe currents in the oceans? Check all that apply.El Niño is a current of water between Australia and North America.Currents occur at the surface of and deep within the ocean.The Coriolis effect contributes to the direction of current flow.Currents often change in unpredictable ways, causing climate change.Wind direction, the spin of Earth, and differences in temperature contribute to currents.

Revolt · Accepted Answer

B: Currents occur at the surface of and deep within the ocean.; C: The Coriolis effect contributes to the direction of current flow.; E: Wind direction, the spin of Earth, and differences in temperature contribute to currents.

Question 2

Imagine that you are sitting on a beach. As you walk toward the water, you see several waves like those in the image in the shallow water. These waves are called breakers.What causes breakers to form?

Revolt · Accepted Answer

A: the rise of the ocean floor

Question 3

Which statement describes the principles on which tidal energy works?

Revolt · Accepted Answer

A: Kinetic energy in the motion of water is converted to electricity.

Question 4

Which statements describe the movement of ocean currents around the globe? Check all that apply.Strong winds force warm water to sink to the ocean floor.The Coriolis effect causes warm and cold water to mix.Cool dense water sinks to the ocean floor.Warm water replaces cool surface water.Wind blowing parallel to the shore causes upwelling of cool water.

Revolt · Accepted Answer

C: Cool dense water sinks to the ocean floor.; D: Warm water replaces cool surface water.; E: Wind blowing parallel to the shore causes upwelling of cool water.

Question 5

The spin of Earth creates the Coriolis effect. This effect causes which current patterns to occur? Check all that apply.

Revolt · Accepted Answer
