In convergences between two oceanic plates OR between an oceanic and a continental plate, the more dense plate subducts under the less dense plate and moves toward the mantle. As the geothermal gradient increases with depth, the subducting plate is exposed to higher and higher temperatures. The oceanic crust undergoes partial melting from exposure to these increased temperatures, and due to the presence of water in the subducting plate. Lithostatic pressure,and the low density of the magma cause it to rise toward the surface. Some magma may solidify underground before reaching the surface; some magma, however, finds its way to the surface, and produces a volcano.

What kind of plates cause volcanoes?
Plates do not cause volcanoes. Volcanoes generally form at the boundaries between plates. They form at convergent and divergent boundaries.
What land features are formed from a convergent boundary?
Convergent boundaries form mountains and volcanoes.
Is forming underwater mountains and volcanoes convergent divergent or transform?
Underwater volcanoes and mountains can form at both convergent and divergent boundaries.
Is Mount Vesuvius near a hot spot divergent or convergent plate boundary?
Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.
How do volcanoes that form over a hot spot differ from volcanoes that form at convergent plate boundaries?
The convergent mountains usually come in ranges, rather than solitary peaks.

Is Mount Vesuvius near a hot spot divergent or convergent plate boundary?
Vesuvius is associated with a convergent boundary between the African Plate and the Eurasian Plate.
Is a volcanic island transform?
No. Volcanoes do not form at transform boundaries. Volcanic islands can form at convergent boundaries and at hot spots.
What kind of boundary do Shield volcanoes form?
hot spots and convergent boundaries
How do volcanoes that form over a hot spot differ from volcanoes that form at convergent plate boundaries?
The convergent mountains usually come in ranges, rather than solitary peaks.
Volcanoes that form along convergent plate boundaries are located?
at the edge of plate collisions
What is the similarities between convergent divergent and transform boundaries?
they both form volcanoes and earthquakes
What kinds of volcanoes form on converging plate boundaries?
Composite cone volcanos are the most common.. Shielding and other types are results from a divergent boundary.
How do convergent boundaries set up conditions that form volcanoes?
It collides with the upper mantle that forms volcanoes with violent eruptions
If composite volcanoes often form along convergent boundaries which plate should be surrounded by the most composite volcanoes?
pacific
