why crust is floating on the mantle

$\huge\bf\pink{Answer}$

The continental and oceanic crusts sit on a thick layer of solid rock known as the mantle. ... They drift because they are sitting on a layer of solid rock (the upper mantle or "asthenosphere") that is weak and ductile enough that it can flow very slowly under heat convection, somewhat like a liquid.

the plates flow on the soft , plastics mantle which is located below the crust
