Why is the Baltic Sea one of the least salty seas in the world?

<p style=";text-align:left;direction:ltr"><strong>The Baltic Sea</strong> is located in northern Europe, and it is one of the arms of the Atlantic Ocean, but the water exchange between them is limited. <strong>The low salinity of the Baltic Sea water is due to several reasons</strong> . The Baltic Sea is almost closed, its outlets are very shallow, and the longest rivers that flow into it pass through regions with a good climate. Mild continental, which keeps water evaporation rates low, and increases the intake water as spring snow melts, and this reduces the salinity of the Baltic Sea waters. <a href="https://www.arabiaweather.com/ar/content/%D8%A8%D8%AD%D8%B1-%D8%A7%D9%84... about the Baltic Sea.</strong></a></p>
