What effect does higher salinity have on water density?

• Increases density

• Decreases density

• No effect on density

• Makes water less dense

How does cooler water temperature affect ocean currents?

• It causes water to sink and drive deep ocean currents

• It causes water to rise and form surface currents

• It has no effect on ocean currents

• It makes water less dense

What role does convection movement play in ocean circulation?

• Creates vertical circulation by density differences

• Stops the movement of ocean currents

• Only affects surface currents

• Has no impact on nutrient circulation

How do surface currents contribute to global climate regulation?

• By transporting heat from the equator to the poles

• By cooling the ocean surface

• By increasing salinity

• By stopping deep ocean currents

What is the relationship between salinity and deep ocean currents?

• Higher salinity causes water to sink and move along the ocean bottom

• Higher salinity causes water to rise to the surface

• Salinity has no effect on deep ocean currents

• Higher salinity makes water less dense
