Ocean Currents and Ekman Transport System

What is the Ekman transport system?

• A system that circulates nutrients in the ocean water

• A system that circulates heat in the ocean water

• A system that circulates oxygen in the ocean water

• A system that circulates carbon dioxide in the ocean water

What causes the surface water to move at an angle to the wind direction?

• Coriolis effect

• Upwelling effect

• Geostrophic current effect

• Ekman transport effect

In which direction do the surface currents shift in the Northern Hemisphere?

• Towards the right

• Towards the left

• Towards the east

• Towards the west

What is the net movement of water in an infinitely deep spiral Ekman transport system?

• At a 90-degree angle to the wind direction

• In the same direction as the wind

• In the opposite direction of the wind

• In a random direction

What is the effect of the Ekman transport system near the eastern seaboard of North America?

• Water moves away from the continent

• Water moves towards the continent

• Water sinks near the continent

• Water rises near the continent

What happens to the water in an upwelling zone?

• It rises to the surface

• It sinks to the bottom

• It moves parallel to the wind

• It moves in a circular motion

What is the importance of upwelling and downwelling in the ocean?

• Recycling of nutrients and temperature regulation

• Creation of waves and tides

• Formation of coral reefs

• Migration of marine animals

In which direction does the water move in a downwelling zone near a continent in the Northern Hemisphere?

• Towards the continent

• Away from the continent

• Parallel to the wind

• In a circular motion

What is the effect of converging winds on the ocean surface?

• Upwelling

• Downwelling

• Cyclone formation

• Anticyclone formation

What is the purpose of the Ekman transport system in the ocean?

• To circulate nutrients and maintain life

• To create ocean currents for navigation

• To generate energy from wave motion

• To regulate the pH level of seawater
