The connection between the plate boundaries and the volcanoes lies in that that they are both part of the geological activity on the planet, and that they are both found on roughly the same places.
On the places where there's plate boundaries, apart from the continental-continental convergent plate boundaries, there's a lot of geological activity. There's cracks that form through the crust, extremely high pressures, adjustments of rocks inside the crust, opining gaps between two plates. That leads to suitable conditions for the high pressure of the mantle layer to be able to push upwards the magma through this places. The magma is very hot, and supported by the high pressure from bellow, it manages to reach the surface relatively easily. Once the magma reaches the surface, it starts to lift up the surrounding area, forming a cone shaped feature, and once the crust is not able to stretch anymore, the magma breaks through it and in the form of lava comes on the surface, forming new crust. If we take a map where the volcanoes and the plate boundaries are marked, we can easily see that their locations correspond, expect for the volcanoes on Hawaii which are formed because of a hot spot.

<h2>
Answer: Supernova Explosion </h2>
A star exists due to the balance between two forces:
1. The gravity force that tries to squeeze the stellar material into the smallest and most compact ball possible.
2. The nuclear force, generating heat and pressure in the center of the star that tries to push all the material out.
Now, when the star has occupied all its nuclear fuel, the expansive pressure can no longer counteract gravity and the star suddenly collapses.
When this happens, a supernova is formed, which causes the expulsion of the outer layers of the star by means of powerful shock waves, enriching the space that surrounds it with heavy elements.
So, it can be said that a supernova is the bright, last breath of a star that is at least five times more massive than the Sun.
