Question

Which three factors are most important in determining the composition of ocean water

Answer 1

First factor: Density of water
This density of water is affected by the level of salt present in it. They are inversely proportional. This means that as the amount of salt in water increases (water becomes more salty), the density of water would decrease

Second factor: Temperature
Temperature affects the composition of water because as temperature increases, the ocean water evaporates and the salt precipitates. Therefore, this factor is essential in determining the rate by which the ocean water evaporates

Third factor: Salinity
This factor helps in determining the amount of salt present in the ocean, i.e, concentration of salt in the water.

Hope this helps :)

Answer 2

The three main factors that help in determining the composition of ocean water are temperature, salinity, and density.  

The temperature helps in determining the rate of evaporation of the sea. Next factor is salinity, it helps in knowing the salty nature of the ocean, and helps in identifying the other essential factor of ocean water, that is, density. The density is one of the most essential factors, as ocean having more salt composition are less dense in comparison to those having less salt.
