Answer to Question 1

Ice (and crust) floats because it is lower density than water (mantle). It is mostly submerged though, because it is lower-density material. If you change the mass, you change the position of the blocks in the water.

Answer to Question 2

The pressure is everywhere the same at the base of any thick column of rock through the crust and upper mantle. It explains variations in Earth's surface elevations in terms of the type and thickness of underlying crust.
