why a ship floats more in sea than in river?
Answers
Answer:
Seawater contains many dissolved minerals and ions that cause it to be denser than freshwater. Because of this, objects seawater exhibit greater buoyancy in seawater than freshwater (Objects displace an amount of water-based on their volume but the buoyancy is determined by the weight of the water displaced).

Answer: Hi...Friend...Here is the Answer....
A ship sink more in river water than in sea water because the density of sea water is more than that of river water due to the presence of impurities.
Explanation:
Archimedes’ Principle states that the force exerted on an object in a fluid is equal to the weight of fluid displaced (moved out of the way) by the object. This force is called buoyant force. The buoyant force pushes upwards against the object. Gravity exerts a downward force on the object (its weight), which is determined by the object’s mass. So if the force exerted downward on the object by gravity is less than the buoyant force, the object will float.
