Question

Why is it easier to swim in the sea than in river?

Answer 1

Heya....The density of the sea water is more than the density of river water. Thus upward thrust is larger. When a body is submerged in sea water the weight of the sea water is displaced is equal to the weight of the river water. A larger body is to be submerged in it. Hence it is easier to swim in a sea water than a river water...✌️✌️

Answer 2

it is easier to swim in sea than river because of its high density resulting out of salt content which won't drown u compared to river
