There are two mechanisms at such a site that can form islands. When two oceanic plates collide, one of them slides beneath the other and plunges into the mantle in a process called subduction. The subducting plate takes some water with it. This water seeps into the hot rocks of the mantle, allowing some of it to melt. This molten rock, called magma, can rise through the crust and form volcanoes that eventually build into islands.

Depending on the subduction rate sediment may be scraped off the top of the subducting plate and pile up into an accretionary prism. Parts of this may push above the ocean surface and form islands.

Is the crust formed or destroyed at a sliding boundary?

At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.


Is the crust formed or destroyed at the sliding boundary?

At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.


Why does oceanic crust dive underneath continental crust?

This process is known as subduction and occurs at convergent plate boundaries because oceanic crust is denser than continental crust.


Crust is destroyed near?

Crust is destroyed at the convergent plate boundaries in Earth. In between the oceanic and continental plates, the subduction of the denser oceanic crust takes place.


What two types of plates does convergent boundaries involve?

There are two types of crust on Earth: oceanic and continental. A convergent plate boundary can involve two plates of oceanic crust, two of continental crust, or one of each.


At what boundary is oceanic crust destroyed?

Oceanic crust is destroyed at convergent plate boundaries, where two tectonic plates collide. Subduction occurs at these boundaries, where the denser oceanic crust is forced beneath the less dense continental crust into the mantle, resulting in its destruction.


What are convertgent boundaries?

A conversion boundary is a place where 2 tectonic plates are mving toward each other. There are 3 types of convergent boundaries OCEANIC CRUST-OCEANIC CRUST OCEANIC CRUST-CONTINENTAL CRUST CONTINENTAL CRUST-CONTINENTAL CRUST They are classified according to their crust


Are convergent boundaries and sea-floor spreading related in any way?

Yes, convergent boundaries and sea-floor spreading are related in the sense that sea-floor spreading can occur at divergent boundaries (where tectonic plates move apart), leading to the creation of new oceanic crust. This new oceanic crust can then be consumed at convergent boundaries (where tectonic plates collide), as one plate is subducted beneath the other.


What type of boundaries creates mountains?

Volcanic mountain ranges are formed from oceanic-continental convergent-subduction boundaries, much like with volcanic islands. When a plate is subducted, the crust forming this plate is heated and melted creating magma which erupts from the crust and creates volcanic mountain ranges.


Is oceanic crust slide under oceanic crust during subduction?

Yes, oceanic crust can slide under oceanic crust during subduction at convergent plate boundaries. This process occurs when a more dense oceanic plate descends beneath another oceanic plate, leading to the formation of a subduction zone.


Is the density low or high for the oceanic crust?

The density of oceanic crust is generally higher than continental crust due to its composition of mostly basaltic rock. This higher density causes oceanic crust to be thinner and denser, leading to its subduction beneath continental crust at convergent plate boundaries.


What two types of crust are involved at this type of convergent boundary?

The two types of Crust is the Continental Crust and the Oceanic Crust.
