What is the definition of ocean currents?

Back

Ocean currents are large-scale movements of seawater that flow through the world's oceans, driven by factors such as wind, water density differences, and the Earth's rotation.

Front

What is convection in the context of ocean currents?

Back

Convection is the process of heat transfer in fluids (like water) where warmer, less dense water rises and cooler, denser water sinks, creating a circulation pattern.

Front

What is the Gulf Stream?

Back

The Gulf Stream is a strong ocean current that originates in the Gulf of Mexico and flows along the east coast of the United States, carrying warm water towards Europe.

Front

What causes the Coriolis Effect?

Back

The Coriolis Effect is caused by the rotation of the Earth, which affects the direction of winds and ocean currents.

Front

How do gyres in the southern hemisphere rotate?

Back

Gyres in the southern hemisphere rotate counterclockwise due to the Coriolis Effect.

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 water density and temperature.

Front

What role does the sun play in ocean currents?

Back

The sun heats the Earth's surface, causing temperature differences in ocean water that drive convection currents and influence wind patterns.

Front

What is the Global Conveyor Belt?

Back

The Global Conveyor Belt is a large system of ocean currents that circulates water around the globe, connecting surface and deep ocean currents.

Front

Why is Charleston warmer than San Diego despite being at the same latitude?

Back

Charleston is warmer than San Diego because it is affected by the Gulf Stream, which brings warm water from the tropics.

Front

What is the effect of wind on ocean currents?

Back

Wind drives surface currents in the ocean, creating patterns of movement that can influence climate and weather.
