Where are 90 percent of earth's volcanoes located why do we find volcanoes there?
I can answer the first part 90 percent of earth's volcanoes are found at plate boundaries.
How does plate tectonics play a role in the formation and eruptions of volcanoes?
Virtually all of the world's volcanoes are located at the boundaries between tectonic plates. It is most common to find volcanoes where an oceanic plate collides with a continental plate. It is the boundary between the Pacific Plate and the continental plates around it that is called the "ring of fire" because so many volcanoes are formed at this boundary. In the collision the denser oceanic plate will be forced underneath of the continental plate. This is called 'subduction', and it usually occurs in destructive plate boundaries. Volcanoes are then formed, when the oceanic plate melts and the molten rock rises, being squeezed up by the forces of the mass above.
What type of volcanic rock do you find in a explosive volcano?
Explosive volcanoes can produce pumice and tuff.
What types of plate boundaries can you find igneous rock?
divirgent
Where do you find volcanoes other than Hawaii?
Volcanoes tend to form at convergent subduction boundaries and divergent plate boundaries. One good example would be the broad ring of volcanoes that have formed around the boundary of the Pacific plate. This is why this region is known as the ring of fire. There is also a very long chain of undersea volcanoes that occur at the mid ocean ridges. In some places these have formed islands such as Iceland. Where subduction occurs (along the west coast of South America, and the west coast of the USA for example) volcanoes form, e.g. Subduction zones also form volcanic island arcs such as the Aleutian island chain in Alaska.

Why do earthquakes happen far away from plate boundaries?
Earthquakes that happen away from plate boundaries are called intra-plate earthquakes. These are caused by the stress of minor fault lines under a certain place. Eg. New Madrid Fault Zone. The UK is a good example of this. England has many fault lines running through, however they are only cracks within the plate not plate boundaries.
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.
Would you except to find plate boundaries here in Canada?
Yes, There are plate boundaries all over the world.
What types of plate boundaries can you find igneous rock?
divirgent
Where do you find most of the zones of earthquakes and volcanoes on Earth's surface?
usually you find most of the zones of earthquakes and volcanoes at a plate boundary.
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.

Convergent boundaries
Where should you find folds and faults?
along tectonic plate boundaries.
