i don't know, that's why i came on here

The Antarctic Plate contains portions of both oceanic and continental crust. Antarctica itself is continental crust.
Oceanic crust is more dense than continental crust. All that water weight compresses the heck out of the material in the plate and also the oceanic crust contains larger percentages of denser elements such as magnesium and iron than the continental crust which also contributes to it's higher density. This sets the conditions for what happens. The more dense oceanic crust will "dive under" continental crust because it is more dense, and all because of the difference in densities.
Two differences are that the oceanic crust is more dense than continental, and continental crust is composed mostly of granite, while oceanic is mostly basalt
The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
It is the crust and mantle,and core

Continental crust and continental crust are made of different types of rock. The rocks in the continental crust do not contain as many of the heavier elements as the ones in the oceanic crust do.

Oxygen, silicon, and aluminum
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
Oceanic crust is thinner and denser than continental crust.
Continental crust is far older than oceanic crust.
It is not. The oceanic crust is thinner than the continental crust!
