Why does the oceanic sink beneath continental crust at convergent boundaries?

Answer 1

The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.
Continental crust is less dense than oceanic crust and so cannot sink below it.

Answer 2

short answer, no... the continental crust is too thick and bouyant to be subducted by thinner oceanic crust.

if stuff goes screwy however you can get oceanic crust thrust over continental crust which is called an ophiolite complex and is generally a bag of hurt

Answer 3

The oceanic crust is more dense than the continental crust and therefore it sinks under it.

Answer 4

We find oceanic crust sinking beneath continental crust because oceanic crust is generally more dense than continental crust.

Answer 5

because the oceanic crust is denser than the continental crust.

Answer 6

The oceanic crust (typically made of basalt) is denser than the continental crust (usually made of granite and other lighter rocks). Denser substances sink lower than less dense substances.
