What are the three factors that affect seawater density? Describe how each factor influences seawater density, including which one is the most important.
Expert Solution
INTRODUCTION:

The density of seawater is affected by the three factors such as temperature, salinity, and pressure. An increase in temperature decreases the density of water by the process of thermal expansion. 

EXPLANATION:

Thermal expansion involves the development of the volume of the substance. In turn, it increases the free movement of the kinetics' energy molecules. Therefore, the density of the seawater decreases with the increase in temperatures.
Salinity is one of the three factors affecting seawater's density by increasing the dissolved content in the water. Hence, the increase in salinity increases the density of water.
The process of compressional effect is affected by the pressure of the density of water. The density increases when the substance compresses by force.
The deep waters are mainly affected by this factor as the upper shallow water compresses them. Hence, the increase in pressure increases the density of water.
