How do volcano's form when oceanic and continental plates collide?
Mountains form where continental and oceanic plates collide by the actions of the plates upon one another. Often one plate pushes up and over the other one, and the upper one creates a row of mountains.
Can continental lithosphere subduct?
Not usually, as the rock they are made of (mostly granite) is too light to sink into the mantle (mostly denser basalt). Small fragments of continental crust can get entrained in a subducting oceanic plate and be dragged down into the mantle as that plate subducts. Where continental crust collides with oceanic crust, it always floats forcing the oceanic crust down and causing it to subduct. Where continental crust collides with continental crust, both plates crumple and compress dramatically, being forced upward into unusually high mountains (e.g. the Himalayas) and downward into deep continental roots that support the weight of those mountains. Nothing subducts in this case. But whole continental plates subducting does not happen, while much more oceanic plate area has been subducted in the history of the earth than the total surface area of the earth.
What are three types of convergent boundaries?
Converging (destructive) plate boundary: where two plates collide. Diverging (constructive) plate boundary: where two plates move away from each other. Transform plate boundary: where two plates move, or grind, past each other. Like the boundary in California.
Differences between oceanic-oceanic and oceanic-continental subduction boundary?
Oceanic to oceanic- one plate sinks under the other Oceanic- Continental ocean crust sinks under the other
What are the types of divergent boundaries?
The 3 general types are constructive, destructive, and conservative boundaries. Constructive (divergent) - plates move away from each other, typically creating a rift Destructive (convergent) - one plate will be subducted, or continental plates collide Conservative (transform) - plates grind past each other, stalling and slipping
What would happen if the continental crust and the oceanic crust went into each other?
In a convergent plate collision between continental and oceanic plates, the more dense oceanic plate would subduct, or move underneath, the less dense continental plate, eventually melting into the mantle at the leading edge.
Why does the oceanic crust go under the continental crust when they collide?
because the ocean base is hevier than the other crust
When two continental plates collide what happens?
When two continental plates collide they form mountains .

How do plate move a convergent boundary?
A convergent boundary is one where two plates are grinding into each other, so the plates are moving toward each other. If one plate more dense than the other, (say a continent and an oceanic plate collide) then the denser plate (the oceanic plate) may be subducted. If two plates of similar or the same density collide, then neither plate will subduct, and crustal thickening may occur. This is the process which formed the Himalayas, resulting from the pressure of two continental plates, the Indian and the Asian.
What is the result when continental plates meet oceanic plates?
If the plates are moving toward each other, the more dense oceanic plate will subduct underneath the less dense continental plate. Mountain ranges and volcanism may result as the water saturated subducting oceanic crust creates molten rock which attempts to rise to the surface.

What are the two ways plates converge?
There are two basic types of convergent boundary. The first is a subduction zone, which occurs at a collision between two plates carry oceanic crust or one carrying continental and once carrying oceanic crust. In such a collision, one oceanic plate will subduct under the other and sink into the mantle. Such a collision produces volcanoes on the overriding plate and will produce mountain ranges on a continent. The other type of convergent boundary occurs when two continent collide. These collisions produce high mountains but not volcanoes. No subduction occurs as continental crust is not dense enough to sink into the mantle.
