Ocean Currents

Front

What is salinity?

Back

Salinity is the measure of the amount of salt dissolved in water. Ocean water is more dense than fresh water at the same temperature due to higher salinity.

Front

What are the two main types of ocean currents?

Back

The two main types of ocean currents are surface currents and deep currents.

Front

What causes certain parts of the ocean to have warmer temperatures?

Back

The uneven heating of the Earth's surface causes certain parts of the ocean to have warmer temperatures.

Front

What happens when surface currents meet continents?

Back

When surface currents meet continents, they are deflected (change paths).

Front

What is the Gulf Stream?

Back

The Gulf Stream is a warm, strong ocean current that flows off the coast of Florida.

Front

What is the difference between surface currents and deep currents?

Back

Surface currents are found in the upper layer of the ocean and are driven by wind, while deep currents occur deeper in the ocean and are driven by differences in water density.

Front

How do ocean currents affect climate?

Back

Ocean currents help regulate the Earth's climate by distributing heat from the equator to the poles.

Front

What role do wind patterns play in ocean currents?

Back

Wind patterns drive surface ocean currents, influencing their direction and speed.

Front

What is upwelling?

Back

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

Front

What is thermohaline circulation?

Back

Thermohaline circulation is a global ocean circulation driven by differences in water temperature and salinity.
