What are 3 types of convergent pate boundaries?
Oceanic-continental plate boundary: where an oceanic plate and a continental plate collide, causing the oceanic plate to subduct beneath the continental plate. Oceanic-oceanic plate boundary: occurs when two oceanic plates collide, with one plate usually subducting beneath the other. Continental-continental plate boundary: where two continental plates collide, leading to the formation of mountain ranges through intense compression and uplifting of the crust.
Which type of lithosphere are colliding at this boundary?
At a convergent boundary, typically an oceanic lithosphere collides with either another oceanic lithosphere or continental lithosphere. When an oceanic plate meets a continental plate, the denser oceanic plate subducts beneath the continental plate, leading to the formation of deep ocean trenches and volcanic arcs. If two oceanic plates collide, one may subduct beneath the other, resulting in the creation of island arcs.
What two different types of convergent boundaries occur?
Oceanic-continental convergent boundaries occur when oceanic plates subduct beneath continental plates, creating deep ocean trenches and volcanic arcs. Oceanic-oceanic convergent boundaries occur when two oceanic plates collide, leading to one plate subducting beneath the other and forming volcanic island arcs.
What are three types of convergent boundaries?
Oceanic-continental convergence: Oceanic plates sink beneath continental plates, creating subduction zones and mountain ranges. Oceanic-oceanic convergence: When two oceanic plates collide, one plate is subducted beneath the other, leading to trench formation and volcanic island arcs. Continental-continental convergence: Two continental plates collide, resulting in the uplift of crust and the formation of mountain ranges.
What plate always subducts?
The oceanic plate always subducts because it is denser than the continental plate. This process occurs at convergent boundaries where two tectonic plates collide, leading to one plate being forced beneath the other and into the mantle.

Why does the oceanic crust go under the continental crust when they collide?
Oceanic crust is denser than continental crust because it is composed of mafic rocks like basalt, whereas continental crust is made of felsic rocks like granite. This density difference causes the oceanic crust to subduct under the less dense continental crust when they collide at convergent plate boundaries.
Which type of lithosphere are colliding at this boundary?

The oceanic plate always subducts because it is denser than the continental plate. This process occurs at convergent boundaries where two tectonic plates collide, leading to one plate being forced beneath the other and into the mantle.
What happends when 2 plates carring continental crust collide?
When two plates carrying continental crust collide, the continental crust is too light to subduct beneath the other plate. Instead, the plates crumple and fold, leading to the formation of mountain ranges. This process is known as continental collision.
What is the difference between oceanic plate and continential plate?
Oceanic plates are young and made of basalt and recent sediments. Continental plates are old and contain continental crust made of old rocks and they are usually considerably thicker than the oceanic plates
What plates meet in subductive zones?
Oceanic plates typically subduct beneath continental plates or other oceanic plates at subduction zones. The denser oceanic plate is forced beneath the less dense continental plate, leading to the formation of features such as deep ocean trenches, volcanic arcs, and earthquakes.
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.
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.
