• They create snowy weather

• They cool them

• They create surface currents

What is the significance of upwelling?

• It brings warm water from the tropics to the poles.

• It decreases winds along exposed coastlines.

• It helps warm the North Atlantic gyre.

• It brings dissolved nutrients to the ocean’s surface.

What causes ocean surface currents?

• Gravitational attraction

• Friction between the ocean and the wind.

• Changes in water density.

• Nutrients becoming available due to upwelling.

In ocean basins, the Coriolis effect helps creates large, circular ocean currents called:

• gyres

• cyclones

• typhoons

• anticyclones

What drives deep ocean currents?

• Equatorial waters are more dense, causing seawater to sink into deep ocean basins.

• Formation of sea ice, increases salinity and the density of seawater, which then sinks into deep ocean basins.

• Equatorial waters are less dense and warmer, displacing cold water in deep ocean basins.

• The oceans are stratified by temperature, so surface waters do not sink into deep ocean basins.

What consequence does the Coriolis effect have on ocean water currents that are changing latitude?

• Moving water is deflected to the left in the Northern Hemisphere and to the right in the Southern Hemisphere.

• Moving water is deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• Moving water is deflected to the right in both hemispheres.

• Moving water is deflected to the left in both hemispheres.
