Ocean Currents

Front

What is a deep current?

Back

A stream-like movement of ocean water that occurs far below the surface.

Front

What forms when cold water sinks?

Back

Deep currents.

Front

What causes surface currents in the ocean?

Back

Wind.

Front

How does salinity affect water movement?

Back

More salinity (saltier) means denser water, which will sink.

Front

What causes the Coriolis Effect?

Back

Earth's rotation.

Front

What is a surface current?

Back

A stream-like movement of ocean water that occurs at or near the surface.

Front

What is upwelling?

Back

The process where deep, cold water rises to the surface, often bringing nutrients.

Front

What is the relationship between temperature and water density?

Back

Colder water is denser than warmer water.

Front

What role does wind play in ocean currents?

Back

Wind drives surface currents by pushing water across the ocean's surface.

Front

What is the effect of Earth's rotation on ocean currents?

Back

It causes the Coriolis Effect, which influences the direction of currents.
