They aren't really. Floating is when an object is held up against the pull of gravity due to the density of the liquid in which the object is resting (though technically, while sitting in a chair you are "floating" but we generally don't use the word that way). Sinking is just an object being pulled down by gravity despite the resistance of the liquid. Sinking is functionally the same as falling, however it generally happens at a slower rate due to the higher resistance (friction) provided by liquid over gasses.
