How does the movement of tectonic plates relate to the formation of volcanoes ?

Well a volcano is made with a convergent boundary. So that is when 2 plates get pushed together

According to the theory of plate tectonics, Earth is an active planet. Its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates. I did an experiment like this before so I am pretty sure that this is the right answer. Good luck!
