Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
The crust not under the ocean is called continental crust. It is thicker and less dense compared to oceanic crust and forms the landmasses on Earth's surface.
Yes it is call a crust 😁
The thickness of the Earth's crust is about 40 km in continental regions, like under mountain ranges. In oceanic regions, such as under the ocean floor, the Earth's crust is much thinner, around 8 km.
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
The mantle is located right under Earth's crust.

crust
The Earth's crust can vary in thickness, but on average it is about 5-70 kilometers (3-44 miles) thick. However, it can be much thicker under mountain ranges and thinner under the ocean floor.
Crust under the oceans is called oceanic crust.
this is the crust which is the very thin layer which has land in the water
The layer that includes the land making up continents and the land under the ocean is the crust, which is the outermost layer of the Earth's surface. It is divided into continental crust, which forms the continents, and oceanic crust, which lies beneath the oceans.
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
Lava....when its under the earths crust its called magma.
oceanic crust
The crust under the ocean is typically about 3 to 5 miles (5 to 8 kilometers) deep.
Oceanic crust is created at mid-ocean ridges and (through the creation of new oceanic crust) is pushed toward a convergent plate boundary where it is subducted. So the oldest oceanic crust would be located at a convergent plate boundary where the oceanic crust is being subducted under continental crust.
