Quizplus · Accepted Answer

The density of water in the Red Sea is higher than that in the Black Sea due to its higher salinity. The higher the density of a liquid, the easier it is for objects to float in it, since there is more upward buoyancy force acting on the object. Therefore, a person would find it easier to float in the Red Sea than in the Black Sea. The temperature difference between the two seas is not relevant to buoyancy, as density is the only relevant factor.
