When two plates collide, one plate (the heavier, denser plate) is subducted beneath the other plate. This plate contains volatiles, such as water. As the subducting plate is buried, it heats up, and the volatiles contained within the crust evaporate into the mantle above. The mantle is not molten in most places, as many people believe. Instead, it is solid but slightly flexible, like frozen cookie dough. When volatiles are added to the mantle, its melting temperature is decreased, and that area melts. This melted portion of mantle is lower in density, and rises through the overlying mantle to the surface, where it erupts in the form of a volcano.
What else can I help you with?
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.
Where most volcanoes are located compared to where plate boundaries are located?
Most volcanoes are located along tectonic plate boundaries, particularly at convergent and divergent boundaries. At convergent boundaries, one plate subducts beneath another, leading to magma formation and volcanic activity. At divergent boundaries, plates pull apart, allowing magma to rise and create new crust, often resulting in volcanic eruptions. Additionally, some volcanoes, known as hotspot volcanoes, can form away from plate boundaries due to mantle plumes.
What kinds of volcanoes form on converging plate boundaries?
Volcanoes that form on converging plate boundaries are typically stratovolcanoes or composite volcanoes. These volcanoes are formed by the subduction of one tectonic plate beneath another, leading to the formation of a volcanic arc and explosive eruptions due to the melting of the subducted plate. Examples include the Cascade Range in the U.S. and the Andes in South America.
Which type of plate boundaries produce volcanoes?
Continental and Oceanic plates.
Why are most volcanoes located near a fault?
Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
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 volcano a convergent boundary?
No. A volcano is not a plate boundary. Most volcanoes on land are associated with convergent boundaries, but many are associated with divergent boundaries and others with hot spots.

Why do volcanoes often occur at convergent plate boundaries?
Because that is where thee is most magma exerting force

At which plate boundaries do most volcanoes form?
The Convergent boundary forms a subduction zone. When the heavier plate reaches 100km the water is released from the submerged plate, and the mantle starts to melt. The mantle rises and a volcano forms on the lighter side plate. Unless it is a continent-continent convergent plate where mostly mountains are forms.
Where are volcanoes most common and why?
Volcanoes are most commonly found along tectonic plate boundaries, particularly at convergent and divergent boundaries. At convergent boundaries, tectonic plates collide, causing one plate to subduct beneath another, leading to magma formation and volcanic activity. At divergent boundaries, plates move apart, allowing magma to rise and create new crust, resulting in volcanic eruptions. Additionally, hotspots, where plumes of magma rise independently of plate boundaries, can also produce volcanoes, as seen in the Hawaiian Islands.
Is a stratovolcano a divergent volcano?
No, a stratovolcano is not a divergent volcano. Stratovolcanoes are typically found at convergent plate boundaries where one tectonic plate is being subducted beneath another, leading to the formation of explosive volcanoes. Divergent volcanoes, on the other hand, are associated with divergent plate boundaries where plates move away from each other, creating rift zones and shield volcanoes.
In what two plate tectonic do volcanoes most occur?
Volcanoes most commonly occur at convergent and divergent plate boundaries. At convergent boundaries, one tectonic plate is forced beneath another, leading to melting and the formation of magma, which can result in volcanic eruptions. At divergent boundaries, tectonic plates pull apart, allowing magma to rise from the mantle and create new crust, often resulting in volcanic activity.
What plate boundary is a composite volcano on?
Composite volcanoes most often are found near subduction zones. They can be found at either oceanic-oceanic convergent plate boundaries, oceanic-continental plate boundaries, or continental-continental plate boundaries. They are especially prevalent in the Pacific Ring of Fire. A few composite volcanoes, however, have been found at divergent boundaries and away from plate boundaries at hot spots.
