∙ 12y agoOur earth ha three layers.1.Crust,which is the uppermost layer where we live.
2.Mantle,which is just under the crust,which is full of heavy metals like Iron and aluminium.
3.Core,which is the innermost layer and is full with high density liquid.Actually metals and other materials are in the form of liquid due to high temperature.Its temperature is exactly 6000 degrees Celsius which is the surface temperature of the sun.So,its very hot there.
Now,as I told crust is the outer part.It is floating like a ship on Mantle which is a great ocean of minerals.The crust if formed of plates.Some are oceanic plates and some are continental plates.All are floating on Mantle that answers why oceanic under continental crust.If you have problems you can ask me.I'm here.

∙ 10y agoBecause the weight of the ocean makes the oceanic crust sit lower than the continental crust, which forces the oceanic crust under the continental crust.
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
Convergent plate margins where oceanic crust is being subducted under continental crust.
because oshieotic crust is under Mantle is thicker
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
A trench and a strata volcano.
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 oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.
The oceanic plates gets subducted or goes under the continental plate
The deepest portions of the subducting plate get pulled under by the subducted plate. This is how the trench is formed. this process is at work when any subduction occurs. An oceanic-continental subduction occurs when ocean crust sinks under continental crust. The oceanic crust sinks because it is colder and denser than the continental crust. At these sites, deep-ocean trenches form, along with coastal mountains.
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.

The Oceanic plate is subducted under the Continental plate because oceanic crust is much more dense than continental crust. The average density of the oceanic crust is 3g/cm^3 while the average density of continental crust is 2.7g/cm^3.
