they will form a mountain
When two oceanic plates meet, which plate gets subducted and why
Either plates gets subducted which is usually the older plate.
The oceanic plates gets subducted or goes under the continental plate
A volcano erupts because of the presure built up in the mantle. There is so much presure in the mantle because when a continental and oceanic plate converge the oceanic plate gets subducted .When the plate gets subducted the matireal in that plate melts making no more space in the mantle and forcing the magma already in the mantle out to the top of a volcano.aFTER THAT HAPPENS new islands will form on top of the oceanic plate (for example hawii is a growing state becase every year a volcano erups creating new islands.

The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.

It gets very hot.
It oxidizes. And turns green.
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.
As the tectonic plate gets subducted it experiences decompression melting where water is being squeezed out of the crust. At the same time the crusts is subjected to heat and pressure which causes the creation of plumes of molten rock. These plumes are now less dense and extremely hot and due to convection processes rise up. This molten rock forms a magma chamber that ultimately makes its way to the surface forming a volcano.
