This document discusses plate tectonics and volcanoes. It explains that volcanoes form at places where tectonic plates meet. Specifically, volcanoes form at divergent boundaries where plates move apart and new crust is created, or at convergent boundaries where plates collide and one plate subducts beneath the other. The document contains diagrams illustrating these concepts.
