It is easier to swim in sea water than in river water.The reason is that sea water or ocean water contains salt which makes its density more than the density of river water.The weight of the man gets balanced by the less immersed part of the body in sea water as compared to that in river water.Thus it is easier to swim in sea water compared to river water.
