The ocean is never pulled under the continent. Oceanic crust--the rock and some sediments, however, slide under the edges of continental crust and are pushed downward toward the mantle in areas of oceanic to continental plate collisions.
This occurs in a subduction zone.
The land under an ocean at the edge of a continent is called the continental shelf. This is the shallow submerged portion of a continent that extends from the shoreline to the continental slope.
continental
The continental shelf lies under the ocean at the edge of a continent and extends about 50 miles from the coast.
Oceanic Crust
No, in the Arctic there is nothing but sea under the ice cap.
Earth's crust is far thicker under the continents.
At the edge of a continent under the ocean lies the continental shelf, a gently sloping extension of the continent covered by shallow seas. Beyond the continental shelf, there is a steeper drop-off known as the continental slope, leading to the deep ocean floor of the abyssal plain.
under the ocean
Antarctica is the name of this southern-most continent. It is covered by polar ice. You might be confused by the fact that there is no land under the polar ice in the north. The Arctic is the name of an ocean; Antarctica is the name of a continent surrounded by the Southern Ocean.
They are not part of any continent. Geographically they would come under Oceania.
Antarctica is a continent. Under all the snow and ice are mountains, valleys and plains above sea level just like other continents.
