Which statement best describes how density is affected by salinity? AKS 3d

• As the salinity of the water decreases, the density increases.

• As the salinity of the water increases, the density increases

• As the salinity of the water decreases, there is no change in density.

• There is no relationship between salinity and density

Refer to the diagram above. Which of the following questions can best be answered by the data presented in the graph above? AKS 3d

• Is there a direct relationship between the density and salinity of ocean water?

• Is there an indirect relationship between the density and salinity of ocean water?

• Does the density of ocean water increase over time?

• Does the salinity of ocean water increase over time?

How do great rivers, such as the Nile, the Amazon and the Mississippi affect the salinity of the oceans they flow into? AKS 3c

• The rivers increase the salinity of the oceans because they remove fresh water.

• The rivers decrease the salinity of the oceans because they remove freshwater.

• The rivers increase the salinity of the oceans because they add freshwater.

• The rivers decrease the salinity of the oceans because they add freshwater.

When water evaporates from the ocean, what happens to the salt in the water?

• The salt does not evaporate and is left behind.

• The salt evaporates with the water and becomes a gas in the air.

• The salt freezes into solid crystals

• The salt condenses and sinks deeper into the ocean
