The water in the oceans is coming from rivers. The river water is taking with it all kinds of material (some of it salt/minerals). As the ocean water is heated by the sun, the water becomes steam and moves in to the atmosphere (forming clouds, for example), but the salt does not vaporate as water does. Therefore the remaining water is salty (more salt for less water).
You can very easily try this by heating some water. First add a little bit of salt in a pot of water, stir it so it dissolves. Taste it before and after heating the water (caution: the water should cool before tasting). You'll get the idea.
Three factors are evaporation and freezing of sea water.

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.
Chitin.
The temperature of ocean water can be affected by the depth. The deeper it gets, the colder the temperature. The current also can affect the temperature of ocean water.

Salinity and temperature
The following are all determined by non-living factors and can affect marine organisms: Temperature Type of soil or rock on ocean floor Salinity Amount of light Water depth (this can change with the tides)

Temperature, salinity, and pressure.
