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.
At transform plate boundaries plates grind past each other side by side. This type of boundary separates the North American plate from the Pacific plate along the San Andreas fault, a famous transform plate boundary that's responsible for many of California's earthquakes.he plates can push against each other, producing a convergent plate boundary, the plates can move apart, forming a divergent plate boundary, or the plates can slip past each other side to side, which geologists call transform plate boundaries. Wherever plates grind against each other, you can expect earthquakes.
