There is no such thing as a subduction boundary, there are divergent, convergent, and transform boundaries. When there is a continental-oceanic convergent boundary (when a continental plate and an oceanic plate smash together) the oceanic plate, because it is more dense sinks into deeper layers of the earth. The area where the two plates meet makes a trench which is a subduction zone. The oceanic plate will melt into the earth and because of the excess lava it rises out onto the continent and makes a volcanic mountain and the lava erupts.
Subduction takes place where oceanic and oceanic crust converge and where oceanic and continental crust converge.
along the the boundarys between 2 or more tectonic plates
Where crust is destroyed
No
Along subduction zones.

they occur i think in the plate boundarys.
In Subduction zones.
No, hotspot volcanoes do not occur along subduction zones. They occur when plates pass over mantle hot spots.
along the the boundarys between 2 or more tectonic plates
Where crust is destroyed
For sure.
Subduction boundaries
No
Along subduction zones.
They occur at convergent boundaries where subduction is occurring.

A compressional bounday is plate boundarys that are being compressed
