Some ocean currents are caused by differences in the density of water from place to place around the globe. What two factors cause differences in ocean water density?
A) differences in water temperature and wind
B) differences in water temperature and phases of the moon
C) differences in the amount of dissolved salts and gravity
D) differences in water temperature and amount of dissolved salts

The density of ocean water is affected by differences in water temperature and amount of dissolved salts. Some animals use ocean currents to move from one area of the ocean to another.

The two main factors that are responsible for the differences in the density of water in oceans are: D) differences in water temperature and amount of dissolved salts

Density is defined as the amount of mass of a substance divided by its volume.

The density of ocean water vary due to the two main factors:

Temperature
Salinity/amount of dissolved salts

Thus, ocean water that is cold and salty is more denser than warm and fresher water.

The mixing of seawater is what affects the circulation of water in the ocean.

Thus, the two main factors that are responsible for the differences in the density of water in oceans are: D) differences in water temperature and amount of dissolved salts
