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 where two tectonic plates collide, causing subduction and the melting of rock. Divergent boundaries also have volcanoes, but they are typically less explosive and occur as a result of magma rising to fill the gap created by the moving plates.
Do explosive eruptions occur more near convergent boundary or divergent boundary?
Explosive eruptions typically occur more frequently near convergent boundaries, where subduction of oceanic plates leads to the formation of explosive composite volcanoes. Divergent boundaries, on the other hand, usually host more passive eruptions marked by effusive lava flows due to the upwelling of mantle material at mid-ocean ridges.
What are the characteristics of divergent-boundary volcanoes and convergent boundary volcanoes?
Divergent boundary volcanoes are associated with mid-ocean ridges where tectonic plates are moving apart, resulting in upwelling magma forming new crust. These volcanoes tend to produce basaltic lava flows with gentle slopes and low viscosity. Convergent boundary volcanoes occur at subduction zones where one plate is being forced beneath another, leading to the melting of rock and explosive eruptions. These volcanoes typically produce andesitic or rhyolitic magma leading to more explosive eruptions with steep-sided cones.
Why is it some areas along where two plate boundaries meet there are volcanos and in some areas there are none?
There are three types of boundaries: 1. Convergent 2. Divergent 3. Transform There are two types of plates: 1. Continental 2. Oceanic Volcanoes only form along convergent and divergent plate boundaries. To be exact, they only form along continental-oceanic convergent boundary, as well as oceanic-oceanic and continental-continental boundaries. At convergent boundaries, volcanoes are formed because of melting crust of the subduction plate (the oceanic plate subducting under the continental plate). They then seep out of the ground as subduction volcanoes. At divergent boundaries, volcanoes are formed because magma rise to the surface to fill the gap where the plates move apart. A third type of volcano that can form is a hotspot volcano. There exists a spot in the ground where magma is continuously rising. However, plates move so as the plates move, the volcanoes move with them. Hence, new volcanoes are formed and this creates a chain of volcanoes, such as Hawaii. Hope this helps!

How do volcanoes that form over a hot spot differ from volcanoes that form at convergent plate boundaries?
Volcanoes that form over a hot spot are usually more isolated and can produce a chain of volcanic islands, like the Hawaiian Islands. In contrast, volcanoes at convergent plate boundaries are often part of larger volcanic arcs and can be associated with more explosive eruptions due to the subduction of oceanic plates beneath continental plates.

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.
How do volcanoes that form over a hot spot differ from volcanoes that form at convergent plate boundaries?
Volcanoes that form over a hot spot are usually more isolated and can produce a chain of volcanic islands, like the Hawaiian Islands. In contrast, volcanoes at convergent plate boundaries are often part of larger volcanic arcs and can be associated with more explosive eruptions due to the subduction of oceanic plates beneath continental plates.
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.
What convergent plate boundaries are active volcanoes not likely to be located?
Active volcanoes are not likely to be located at convergent boundaries where an oceanic plate subducts beneath a continental plate because the melting point of the oceanic crust is lower, causing it to melt and create volcanic features before reaching the surface. Instead, active volcanoes are more commonly found at divergent boundaries where plates move apart.
What type of plate boundary would have less silica content?
A divergent plate boundary would have less silica content compared to a convergent plate boundary. Divergent boundaries involve the separation of tectonic plates, with new oceanic crust forming from magma that is relatively low in silica content. In contrast, convergent boundaries involve the collision of tectonic plates, resulting in the melting of crust with higher silica content, leading to more explosive volcanic activity.
Do composite volcanoes have viscous lava?
Volcanoes are named after the lava that comes out.viscous volcanoes (or acid and dome) are the same thing.the lava comes to the surface close to subduction zones,which are found at convergent plate boundaries.it is high in silica content and does not flow easily.it contains gas which cannot escape easily,so eruptions may be explosive and violent.eg Caribbean volcanoes
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.
