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.

Convergent plate boundaries have volcanoes because one plate is being forced beneath another plate, a process known as subduction. As the subducting plate moves deeper into the mantle, it melts and creates magma that rises to the surface, causing volcanic activity. Additionally, the collision of the two plates can also generate magma and lead to volcanic eruptions.

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.
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 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.
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?
Most volcanoes form at convergent plate boundaries, where one tectonic plate subducts beneath another. Additionally, some volcanoes also form at divergent plate boundaries, where tectonic plates move apart and create space for magma to rise to the surface.
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.
What volcano is formed along colliding boundaries?
Most of the volcanoes at convergent boundaries are stratovolcanoes.
What plate boundary is a composite volcano on?
A composite volcano is typically found at convergent plate boundaries, where one tectonic plate is pushed beneath another in a process known as subduction. The melting of the subducted plate creates magma that rises to the surface and forms the volcano.
What kind of boundaries can cause earthquakes and volcanoes?
Earthquakes can occur at any type of plate boundary, but the most powerful earthquakes tend to occur at convergent boundaries and at transform boundaries.
Where are earthquakes or volcanoes likely to occur?
Earthquakes are likely to occur along tectonic plate boundaries where there is movement and stress in the Earth's crust. Volcanoes are likely to occur at convergent plate boundaries, divergent plate boundaries, and hotspots where magma from the Earth's mantle reaches the surface.
