Here's a more detailed explanation:

* Buoyancy is an upward force exerted by a fluid (liquid or gas) that opposes the weight of an object immersed in it. This force is caused by the difference in pressure between the top and bottom of the object.

* Archimedes' Principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. This means that the more fluid an object displaces, the greater the buoyant force.
