Ocean Currents Review

Front

What is the density of hot water compared to cold water?

Back

Hot water is generally less dense than cold water.

Front

What causes surface currents in the ocean?

Back

Surface currents are caused by winds.

Front

What happens to warm water when it loses energy?

Back

Warm water cools down, which can increase its density.

Front

How does the ocean help regulate carbon levels in the atmosphere?

Back

The ocean can absorb atmospheric carbon dioxide.

Front

What effect does adding a large amount of salt to ocean water have?

Back

The salinity and density of the water would both increase.

Front

Define ocean currents.

Back

Ocean currents are large-scale movements of water within the oceans, driven by factors such as wind, temperature, and salinity.

Front

What is the role of wind in ocean currents?

Back

Wind drives surface currents, influencing the movement of water in the ocean.

Front

Explain the relationship between temperature and water density.

Back

As water temperature increases, its density decreases; as temperature decreases, density increases.

Front

What is salinity?

Back

Salinity is the measure of the amount of salt dissolved in water.

Front

How do deep ocean currents form?

Back

Deep ocean currents can form when water becomes denser due to cooling or increased salinity.
