Salinity can vary because of water temperature, rivers emptying into the ocean and mixing with ocean water, ice forming or melting, evaporation and precipitation. I think temperature is the biggest reason.
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.

Oceans are big water bodies. Salinity is due to the presence of minerals in water.
The amount of salt in the water. Near the surface of the open oceans salinity is in general between 3.3% and 3.7%
salinity
There are several factors that affect salinity. Some of the main factors include evaporation and precipitation which will affect the salinity of oceans and seas.
In any body of water; usually oceans.
i think no.
3.1-3.6% salinity
The world's oceans have a salinity of about 3.5%
AnswerAll oceans have salt in them. The average salinity of all oceans is 35 parts per thousand. Salinity does vary according to depth and location. Areas of the ocean located near onshore river runoff typically have a lower salinity. Areas near the tropics with high evaporation rates tend to have higher salinity.
