Ocean Currents

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the apparent deflection of moving objects (like air and water) caused by the rotation of the Earth on its axis.

Front

What are ocean currents?

Back

Ocean currents are continuous flows of ocean water that move in specific directions due to various factors including wind, water density differences, and the Coriolis Effect.

Front

What type of current is the Gulf Stream?

Back

The Gulf Stream is a warm current that originates in the Gulf of Mexico and flows along the east coast of the United States.

Front

How does the Coriolis Effect influence water movement in the northern hemisphere?

Back

In the northern hemisphere, the Coriolis Effect causes water to move in a clockwise direction.

Front

How does the Coriolis Effect influence water movement in the southern hemisphere?

Back

In the southern hemisphere, the Coriolis Effect causes water to move in a counter-clockwise direction.

Front

What factors influence the direction of ocean currents?

Back

The direction of ocean currents is influenced by wind patterns, the Coriolis Effect, the shape of coastlines, and differences in water temperature and salinity.

Front

What is the role of wind in ocean currents?

Back

Wind drives surface ocean currents by exerting frictional force on the water, causing it to move in the direction of the wind.

Front

What is thermohaline circulation?

Back

Thermohaline circulation is a global ocean circulation pattern driven by differences in water density, which is affected by temperature (thermo) and salinity (haline).

Front

What is the significance of the Gulf Stream?

Back

The Gulf Stream plays a crucial role in regulating climate, particularly in Europe, by transporting warm water from the tropics to the North Atlantic.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, often enhancing marine productivity.
