se 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.
