Mount Hood is part of the Cascade Volcanic Arc, which formed as a  result of the convergent boundary between the North American Plate  and the Juan de Fuca Plate.Edit.ransform boundary: when two plates grind past each other. Convergent boundary: when the two plates collide.
Three types of tectonic pl ate boundaries exist: convergent, divergent and transform. Mountains are formed by plate convergence. Plate convergence describes tectonic plate movement that results in the collision of two plates. These slow-moving collisions shift the plates only a few centimeters a year, but are powerful enough to form large mountain ranges over time.
