Mid-latitudinal zones lies between 25° to 35° north and south of the equator.
In this zone, the rainfall is less and the supply of fresh water from rivers is also low.
This region experiences high-temperature conditions which are marked by the presence of hot deserts of the world. These high-temperature conditions lead to a high rate of evaporation.
Thus, the salinity of the seas is found to be higher in mid-latitudinal zones.
