Which sea has the lowest salinity among the seas of the world?
- A.Red Sea
- B.Mediterranean Sea
- C.Baltic Sea
- D.Arabian Sea
Correct answer
Explanation
The correct answer is C, the Baltic Sea. It receives a very large river inflow from northern Europe, lies in a cool region where evaporation is slight, and exchanges water with the North Sea only through the narrow Danish straits, so its water is brackish rather than fully saline, especially in the Gulf of Bothnia. Option A is wrong because the Red Sea is at the other extreme, the saltiest of the open seas, since no permanent river reaches it and evaporation is intense. Option B is wrong because the Mediterranean is also more saline than the open ocean, for the same reason of heavy evaporation in an enclosed basin. Option D is wrong because the Arabian Sea has a salinity close to the ocean average. Remember the pair: Red Sea the saltiest, Baltic the least salty.
