What regions of the earth contribute to the oceans salinity?

Salinity. Although everyone knows that seawater is salty, few know that even small variations in ocean surface salinity (i.e., concentration of dissolved salts) can have dramatic effects on the water cycle and ocean circulation. Throughout Earth's history, certain processes have served to make the ocean salty. read more

For one thing, ocean water is slightly alkaline instead of acid. More to the point, it's got all those minerals dissolved in it, so is fairly saturated and commonly precipitates minerals, sometimes through biological processes, e.g. formation of limestone. read more

Throughout Earth's history, certain processes have served to make the ocean salty. The weathering of rocks delivers minerals, including salt, into the ocean. 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. read more
