Usually evaporation, but keep in mind that when water freezes (like the polar ice areas) the water molecules tend to crystallize with only water molecules, which pushes other stuff like salt out, resulting in higher salinity in the water that is left. A fascinating side article is in the link below.

Is salinity high on open ocean?
In open ocean evaporation affects the salinity of the oceans, in closed oceans the lack of sunrays cause greater salinity levels.

What is the salinity in the oceans?
The amount of salt in the water. Near the surface of the open oceans salinity is in general between 3.3% and 3.7%
Describe the oceans and explain how the water cycle affects the salinity of the ocean?
Oceans are big water bodies. Salinity is due to the presence of minerals in water.
What is the measure of dissolved salts in the oceans called?

What factors affects 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.
Where is Salinity found?
In any body of water; usually oceans.
Does the water in the Atlantic and Pacific oceans have the same salinity?
i think no.
What is percantage of salt in oceans water?

How salty are all the seas?
The world's oceans have a salinity of about 3.5%
What oceans have salt in them?
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.
