Currents, salinity, and Coriolis Effect

Front

What causes surface currents north and south of the equator to move in different directions?

Back

The rotation of the Earth.

Front

What is the Coriolis Effect?

Back

The deflection of circulating air toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere due to Earth's rotation.

Front

What causes the movement of ocean currents?

Back

Temperature and salinity differences.

Front

True or False: Surface currents affect coastal climates.

Back

True.

Front

How does convection cause ocean currents?

Back

During convection, warm water loses energy, cools, becomes denser, and sinks.

Front

What is salinity?

Back

The concentration of salts in water.

Front

How does salinity affect water density?

Back

Higher salinity increases water density.

Front

What role does wind play in ocean currents?

Back

Winds drive surface currents by transferring energy to the water.

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 ocean currents?

Back

Temperature differences in water create density variations, driving currents.
