The process in the water cycle that increases the salinity of ocean water is evaporation. As water evaporates from the oceans, it leaves behind its salt content, causing the remaining water to become more saline. When this water vapor condenses and falls back into the ocean as precipitation, it is essentially fresh water, so this cycle of evaporation and precipitation increases the overall salinity of the oceans over time.
Salinity refers to the concentration of salt in water. Salinity typically increases with depth in oceans due to the processes of evaporation and freezing which leave behind salt in the water, as well as the mixing of water masses within the ocean.
Evaporation near the equator increases the salinity of the ocean water because it removes fresh water and leaves behind the salts, making the water more saline. This can lead to higher salinity levels in tropical regions compared to other areas of the ocean.
Salinity of the ocean water is defined as the dissolved salt content in a body of water. The salinity of the ocean is 3.5%, the salinity increases as you approach the equator and decreases as you approach the poles.
When the ocean water freezes, it increases the salinity. When the ocean water freezes at the surface, ice will float on top of water because ice is less dense than liquid water. The dissolved solids are squeezed out of the ice and enter the liquid water below the ice. This increases the salinity of the water. The density of the water also increases.
The highest surface salinity in the world ocean is found in the Red Sea.
There are different kinds of process that deeply affects the salinity of ocean water. Continental deflections, Coriolis Effect, convection current and also evaporation.

Evaporation increases salinity in the ocean by concentrating the salt content in the remaining water. Freezing increases salinity by excluding salt from the ice crystals that form, leaving the surrounding water saltier.
There are a number of things that could happen to the salinity of an ocean if it's depth increased. The salinity would likely also increase.

Evaporation leaves salt behind. So as ocean water decreases, the percentage of salt increases, increasing salinity. As evaporation increases, rainfall also increases, thus it decreasing the salinity of ocean water.
The density of the water increases with the salinity, so saline water is denser and sinks to the bottom. Temperature is also a factor, however. Cold, saline water is the densest
rain, snow, and melting ice add fresh water to the ocean, lowering the salinity there. Salinity is also lower near the mouths of large rivers. These rivers empty great amounts of fresh water into the ocean.
Oceans are big water bodies. Salinity is due to the presence of minerals in water.
Salinity refers to the concentration of salt in water. Salinity typically increases with depth in oceans due to the processes of evaporation and freezing which leave behind salt in the water, as well as the mixing of water masses within the ocean.
Ocean currents,The sun,and human activities
The major source of oceanic salinity is the dissolution of ions from rocks on land that are carried into the ocean by rivers. This process adds various salts to seawater, contributing to its overall salinity. Additionally, hydrothermal vents on the ocean floor can also introduce elements and minerals that affect salinity.
