GEOLOGY

Detailed explanation-1: -When salt is dissolved in water, as it is in ocean water, that dissolved salt adds to the mass of the water and makes the water denser than it would be without salt. Therefore due to increase in density of fluid, upward Buoyant force will increase due to which object will float better in salt water.

Detailed explanation-2: -The reason for this is that sea water is denser than fresh water. The salt combines with the water molecules, giving sea water more matter per cubic inch than fresh water when the same volume of water is compared. Therefore, your body will float more easily in the sea.

Detailed explanation-3: -The reason is: Buoyancy – saltwater gives more buoyancy than freshwater because of the higher density of saltwater. Buoyancy makes it easy for the body to stay high in water, thus all other factors being kept equal, one can swim faster in salt water than in freshwater.

Detailed explanation-4: -We know that upthrust from water is required for swimming and the density of the fluid matters in order to gain that upthrust. The denser the fluid, more the upthrust and this is why it is easier to swim in sea water than fresh river water. Q.
