Well we know why volcanoes happen at the plate boundaries-
because all the tectonic plates are floating on magma from the mantle and when the plates move they create gaps where magma can shoot up.
But some volcanoes happen in the middle of tectonic plates. Why?
Well, I THINK (I'm not 100% sure) that it is to do with tectonic plates having mini fault lines within them. So these can create smaller gaps where the magma can rise through. Also, these have also been variously attributed to mantle plumes. A mantle plume is an up-welling of abnormally hot rock within the Earth's mantle. The hypothesis of mantle plumes is not universally accepted though. :D
I hope this helped- forgive me if I am wrong.

oooh.... DNA
What else can I help you with?
Volcanos form a ring of fire around the plate boundaries in the pacific ocean how might this provide evidence that the plates are moving?
Volcanoes are ofrenda found in subduction
Where do earthquakes and volcanos occur?
Volcanoes tend to form at convergent tectonic plate boundaries where subduction is occurring (such as the western coast of South America) and at divergent plate boundaries where two tectonic plates are moving apart (e.g. the Mid-Atlantic-Ridge and Iceland). Earthquakes also occur at convergent boundaries and in fact these tend to cause the strongest earthquakes. Earthquakes also occur at transform boundaries (such as the San Andreas fault) however these do not tend to cause the formation of volcanoes. So to find volcanoes and large earthquakes you should be looking at convergent plate boundaries where subduction is occurring.
Are hot spots near plate boundaries?
No, Hot Spots can be in the center of plates. An example of a Hot Spot is the Hawaiian Islands.
Why do you find volcanoes at convergent and divergent boundaries but not at transform boundaries?
Convergent and divergent boundaries melt rock in the upper mantle while transform boundaries do not. Convergent boundaries that involve at least one oceanic plate form subduction zones, where an oceanic plate plunges into the mantle. Volatiles carried into the mantle lower the melting point of the rock there, allowing magma to form.At divergent boundaries the crust becomes thinner. This reduces pressure on the upper mantle, thus lowering melting points and generating magma.Transform boundaries have no such means of producing magma.
Why is there no volcanoes in the middle of the Caribbean sea?
The middle of the Caribbean Sea is over the middle of the Caribbean Plate. Most volcanoes form near the edges of tectonic plates. For example, the lesser Antilles are composed in part of volcanoes at the margin of the Caribbean Plate.
What boundary is it when a volcano formed?
Volcanoes can form at convergent boundaries, divergent boundaries, and at hot spots away from any plate boundary.
What boudaries produces volcanoes?
Convergent boundaries produce volcanoes. Volcanoes form when an oceanic plate and a continental plate converge, causing the oceanic plate to subduct. The subduction causes a magma chamber to form which feeds the volcano when it erupts.
What plate process causes volcanoes to form at their boundaries?
the plate of your mom
At what type of boundary do hot-spot volcanoes form at?
Hot-spot volcanoes form at intraplate boundaries, where a plume of hot magma rises from deep within the mantle, creating volcanic activity away from tectonic plate boundaries.
Volcanoes form on what plate?
Volcanoes form on tectonic plates at plate boundaries where magma from the Earth's mantle can rise to the surface. This typically occurs at divergent or convergent plate boundaries where there is movement and interaction between the plates, leading to volcanic activity.
Do volcanoes form near colliding plate boundaries?
yes
Which plate boundaries do not form volcanoes?
dining table plates
What is the difference between hotspot volcanoes and volcanoes formed at plate boundaries?
Hotspot volcanoes form over a fixed hotspot in the mantle, resulting in a chain of volcanoes as the tectonic plate moves over it, like the Hawaiian Islands. Volcanoes at plate boundaries are formed by the interaction of tectonic plates, where one plate is forced under another (subduction) or plates move apart (divergence), creating volcanic activity along the boundary, like the Ring of Fire.
Volcanoes most commonly form where?
volcanos mostly form on tectonic plate boundaries and hot stops
Volcanoes that form far from plate boundaries form as the result as?
Hot spots!
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.
Where does cinder cone volcanoes form?
cinder cone volcanoes usually form around lithospheric plate boundaries.
