Ocean Currents

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as air and water, caused by the rotation of the Earth on its axis.

Front

How does the Coriolis Effect influence ocean currents in the Northern Hemisphere?

Back

In the Northern Hemisphere, the Coriolis Effect causes ocean currents to move in a clockwise direction.

Front

What factors affect the density of deep ocean water?

Back

Temperature and salinity affect the density of deep ocean water.

Front

What happens to cool air or water in convection?

Back

Cool air or water sinks in convection.

Front

What is the Global Conveyor Belt?

Back

The Global Conveyor Belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity, which moves water around the globe.

Front

What is the primary driver of surface ocean currents?

Back

Wind is the primary driver of surface ocean currents.

Front

What is the difference between surface currents and deep ocean currents?

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by differences in temperature and salinity.

Front

What role does salinity play in ocean water density?

Back

Higher salinity increases the density of ocean water, causing it to sink.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold water rises to the surface, often bringing nutrients that support marine life.

Front

What is thermohaline circulation?

Back

Thermohaline circulation is the part of the global ocean circulation driven by differences in temperature and salinity.
