Western boundary currents tend to be

all currents are the same temperature

Surface winds cause currents in the ocean by

transferring wind energy to ocean water

wind absorbing energy from ocean water

Surface currents north of the equator flow clockwise, but surface currents south of the equator flow counterclockwise due to the Coriolis effect.

They both flow the same direction, which is clockwise.

They both flow the same direction, which is counterclockwise.

During a strong El Niño event, the news media might be expected to cover _______.

drought on the western coast of South America

flooding in Indonesia and Australia

record high fishing catches in Southeast Asia

Records indicate that the ocean is warming faster in the Arctic polar regions than elsewhere, releasing additional freshwater into the North Atlantic. If that continues, a possible consequence could be __________

slowing of the deep ocean circulation

an increase in upwelling in the arctic

faster moving deep ocean circulation

Of the following statements about deep-ocean currents, which is NOT true?

Deep-ocean currents travel faster than ocean surface currents.

Deep-ocean currents are initiated near Antarctica and in the North Atlantic Ocean, where cold, dense water sinks.

Deep-ocean currents are important regulators of global climate.

Deep-ocean currents contain water with high oxygen concentrations.

Of the following conditions, which is NOT related to strong El Niño events?

Increase in the strength and consistency of the trade winds

Decrease in productivity along coastal South America

Increase in sea surface temperatures in the eastern Pacific Ocean

Why does upwelling occur along the west coast of South America under normal conditions?

Winds moving westward in the South Pacific drive ocean currents toward the west; deep water rises to replace water driven westward.

Winds moving northward in the South Pacific drive ocean currents toward the north; deep water rises to replace water driven northward.

Winds moving eastward in the South Pacific drive ocean currents toward the east; deep water rises to replace water driven eastward.

Winds moving southward in the South Pacific drive ocean currents toward the south; deep water rises to replace water driven southward.

What would you expect weather to be like in Indonesia if the western coast of South America were experiencing unusually warm, wet weather?

Indonesia would be experiencing unusually dry weather.

Indonesia would be experiencing unusually cool weather.

Indonesia would be experiencing unusually warm weather.

Indonesia would be experiencing unusually wet weather.

Under which conditions are droughts and wildfires common in Australia and Indonesia?

under Walker Circulation conditions

What is the overall effect of the stronger than normal trade winds typical of La Niña conditions?

lowering of the East Pacific ocean temperature from normal conditions

raising of the East Pacific ocean temperature from normal conditions

flipping of the East Pacific ocean current direction from normal conditions

swapping of the Pacific high and low pressure zones from normal conditions

A deep and powerful southward subsurface current that flows under the Gulf Stream in the North Atlantic is the __________.

North Atlantic Subtropical Gyre

Why do the fishermen of Peru and South America dislike a strong El Nino?

El Niño shuts off upwelling and nutrients needed for the marine food chain do not rise to the surface

El Niño causes strong winds and currents which move fish westward

El Niño bring cold water to the surface which kills the base of the food chain

Which of the following is an INCORRECT statement about El Niño and La Niña?

Both occur in the Atlantic Ocean

El Niño is a warming and La Niña is a cooling of the Pacific Ocean

Neither are considered "storms"

Which statement correctly describes the motion of water particles due to the action of waves?

they rise and fall in a circular motion

they travel from one crest to another

they move in opposite direction of the wave
