Give the reasons for the Sow salinity of Baltic sea.

1.	Give the reasons for the Sow salinity of Baltic sea.
Answer» 1. Baltic sea is a brackish mediterranean sea located between Central and Northern Europe. 2. The Baltic sea’s salinity is much lower than that of ocean water. 3. Baltic is a small sea on a global scale. 4. The causes for the low salinity of the Baltic sea are a) The abundant fresh water run off from the surrounding land. b) The shallowness of the sea. c) The flow of fresh water into the sea from approximately two hundred rivers and the introduction of salt from the south builds up a gradient of salinity in the Baltic sea. d) The Baltic sea is only connected to the world’s oceans by the narrow and shallow waters of the Sound and Belt-sea. e) This limits the exchange of water with the North sea and means that the same water remains in the Baltic for a lot of years. For all the above reasons the salinity of the Baltic sea is less than that of the salinity of the oceans.
