Explain how the Sun's heat energy affects ocean water temperature.

• It causes the water to freeze.

• It causes the water to evaporate.

• It warms the surface water, creating temperature differences.

• It cools the water, creating icebergs.

How does salinity affect the density of ocean water?

• Higher salinity decreases density.

• Higher salinity increases density.

• Salinity has no effect on density.

• Lower salinity increases density.

Describe the role of salinity in oceanic convection currents.

• Salinity makes water lighter and causes it to rise.

• Salinity makes water denser and causes it to sink.

• Salinity has no role in oceanic convection currents.

• Salinity causes water to evaporate.

Which of the following statements is true about the relationship between temperature and water density?

• Warmer water is denser than colder water.

• Colder water is denser than warmer water.

• Temperature does not affect water density.

• Both warmer and colder water have the same density.

What evidence supports the idea that the Sun's heat energy causes oceanic convection currents?

• The Sun's heat causes water to freeze.

• The Sun's heat creates temperature differences in ocean water.

• The Sun's heat has no effect on ocean water.

• The Sun's heat only affects land temperatures.

How do temperature and salinity differences work together to create oceanic convection currents?

• They cause water to evaporate.

• They create density differences that drive water movement.

• They stop water from moving.

• They make water lighter and cause it to float.

Which of the following is a consequence of oceanic convection currents on global climate?

• They cause deserts to form.

• They regulate temperatures by distributing heat.

• They have no impact on climate.

• They cause the Earth to cool down.
