The oceanic crust is formed at mid Atlantic ridge.A chain of under water mountain range with active volcanic activities pushes apart the new ocenic crust.Note that if ocean floor is created then it is also consumed else where at a subduction zone situated in Pacific Ocean so called ring of fire.Otherwise the volume of earth would go on increasing.

At what kind of boundary does oceanic lithosphere plunge beneath and overriding continental plate?
Convergent oceanic-continental boundary
What kind of rocks make up continental crust and oceanic crust?
granite and basalt
What kind of plate boundary does subduction take place at?
A convergent plate boundary. a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary.
What kind of plate boundary has the most explosive volcanoes?
Convergent with the oceanic plate subducting under the continental plate.
What kind of boundary is a volcano?
volcanoes are caused by subduction. it could be an oceanic plate sub-ducting under a continental plate which would result in a coastal volcano or it could be an oceanic plate sub-ducting under another oceanic plate, which would result in a volcanic island.
What kind of boundary is located at the mid ocean ridge?
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust.
What kind of crust is found under the ocean?
oceanic crust
Oceanic-continental convergent plate boundary.?
oceanic-continental convergent plate boundary has what kind of crustal rocks
At what kind of boundary does oceanic lithosphere plunge beneath and overriding continental plate?
Convergent oceanic-continental boundary
What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
What kind of rocks make up continental crust and oceanic crust?
granite and basalt
What is the plate with oceanic crust sinking under one another plate with oceanic crust?
When one plate sinks under the other, it is callled subduction, no matter what kind of plate it is. When two oceanic plates collide, they form trenches(i.e. the mariana trench). Hope this answers your question!!!
What kind of plate boundary does subduction take place at?
A convergent plate boundary. a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary.
What kind of crust are Plates made of?
rocky almost cement crust like granite found in continental crust and basalt found in oceanic crust
Is tuff formed in the oceanic crust?
No. Tuff is not formed in the crust but on the surface. Tuff is a kind of rock formed from volvanic ash.
Pulling forces form what kind of mountains?
I believe that this question has to do with earth science. When two continental plates come together, a convergent plate boundary, mountains form. If an oceanic plate and a continental plate converge, or come together, a subduction zone is form and the oceanic plate subducts under the continental usually because the oceanic plate is less dense. Hope I kind of answered the question..?
What are two kind of crust that a tectonic plate may contain?
The two types of crust may be called continental crust and oceanic crust. They can also be called granitic and basaltic crust respectively.
