The crust rides or floats on the mantle. :)

The continental crust is less dense
Continental crust is less dense than oceanic crust.
Crust
It's ... um, denser. The continents (largely SiAl, silicon-aluminium) essentially "float" on the denser SiMa (silicon-magneisum) layer.
it is either the principle of isostasy or tectonics.
There called tectonic plates, and they do not float on anything.

the oceanic crust is more dense therefore it sinks lower than continental crust
plates of the earth's crust that float on top of the molted mantle layer.
it is floating on it
No, they float on it.
Because it can and it's free.
Continental crust is less dense than oceanic crust.
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
Earth is made up of: the inner core, the outer core, the mantle, and the crust. The crust of the earth, or the outer rocky layer, is divided between oceanic crust and continental crust. These crusts float atop the mantle, which is made up of very hot molten rock. All of the continents, including Australia, are constantly moving, or floating.
