Why are convergent volcanoes more explosive than divergent volcanoes?

Convergent Volcanoes are of a different composition, they are more viscous so rise much more slowly and they have a much greater amount of CO2, SO2 and most importantly H20 which causes an immense buildup of steam pressure! Why does aP ressure Cooker become like a dangerous bomb if left unattended while an open pot will just boil off? The same is true here!

Are volcanoes more common along a convergent or divergent boundary?
Volcanoes are more common along convergent boundaries
Do explosive eruptions occur more near convergent boundary or divergent boundary?
Convergent boundaries.
What do convergent boundaries cause?
A divergent boundary between two oceanic crusts can cause mid-ocean ridges such as the Mid-Atlantic Ridge. A divergent boundary between two continental crusts can cause rift valleys like the East African Rift Valley. Many volcanoes can be formed from the outflow of magma onto Earth's surface, and even volcanic islands such as Iceland can be formed.
Why are some volcanoes more destructive then others?
Well, all volcanoes create land, but explosive volcanoes also destroy land. Explosive volcanoes are explosive because they have a lot of gas and pressure inside them, and then the pressure suddenly drops. That's when the volcano starts erupting.
Why do volcanoes tend to be more explosive at convergent boundaries than at divergent boundaries?
The large stratovolcanoes of the Cascades and the Andes are magnificent pieces of geologic architecture when it comes to strength of a mountain. So immense pressures can build. Therefore, when the mountain finally does erupt, it will be (again, not 100% always, but "pretty much") highly explosive, and very dangerous, not just from the blast, but also from pyroclastic flows of water, lava, and various superheated debris.

Convergent boundaries.
What boundaries are the 3 types of volcanoes located on?
Divergent and convergent plate boundaries. You can look up more info on google.
What types of valcanoes would be the most explosive?
Volcanoes with more viscosity are more explosive.

When does volcanoes occur more often?
Volcanoes occur at divergent and convergent plate boundaries due to the fact that crust is either being destroyed or created. Volcanoes also occur at hotspots, for example in Hawaii. Hotspots occur where the crust is particularly thin or weak, and plumes of magma rising from the asthenosphere (between upper mantle and the crust) end up giving rise to volcanoes or volcanic islands.
Is the pressure at the throat of a convergent-divergent nozzle highest or lowest?
coz area is less thats y pressure is more
Does hot spot volcanoes tend to erupt more explosively than other volcanoes?
No they do not erupt more explosively. It depends on its gas and its viscosity. Kilauea in Hawaii does not erupt more explosive.

Why is the boundary of the Nazca Plate considered divergent rather than convergent?
The Nazca plate has more than one boundary. The western and northern boundaries are divergent as the plates are moving apart from one another. However, the Nazca plate's eastern boundary is convergent as it collides with and subducts under the South American Plate.
What is the most dangerous kind of volcano?
In general, composite volcanoes are the most dangerous volcanoes because they are more explosive than the other types.
