Question

What are the content which increases the salinity in the water?

Answer 1

Salt when you cooking beside the sea (machuaras)

Answer 2

Answer:

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
