Upwelling and Downwelling

Movement of large volumes of cold, nutrient rich bottom water.

• downwelling

• gyre effect

• upwelling

• equatorial current shift

Upwelling occurs in a ring around which continent?

• Australia

• South America

• Antarctica

• Africa

Ekman transport can cause wind moving along the coastline to push water out to sea (away from the coast). This results in:

• downwelling

• upwelling

• equatorial upwelling

• circumpolar currents

If winds are moving water towards the coastline, this will lead to:

• upwelling

• downwelling

• equatorial upwelling

• circumpolar currents

• Ekman transport

• upwelling

• downwelling

What is the main benefit of upwelling for commercial fishing industries?

• It increases the water temperature, making it ideal for fish.

• It brings nutrients to the surface, supporting large populations of fish.

• It reduces the salinity of the water, attracting different species of fish.

• It creates calm water conditions, making fishing easier.

why does coastal upwelling commonly result in productive fisheries?

• nutrient rich water is brought to the surface, supporting growth of plankton.

• the upwelling bring the fish to the surface.

• its the ocean, there are fish everywhere.

• the great ocean conveyor provides the nutrients.

Differentiate between upwelling and downwelling in the ocean.

• Upwelling brings cold, nutrient-rich water to the surface, supporting marine life, while downwelling redistributes heat and dissolved gases.

• Downwelling supports marine life by bringing cold, nutrient-rich water to the surface.

• Upwelling redistributes heat and dissolved gases in the ocean.

• Upwelling brings warm, nutrient-poor water to the surface.
