Plate Boundaries
The Ring of Fire is the result of plate tectonics. The edges of several tectonic plates meet along the Ring of Fire, resulting in a convergent boundary, a divergent boundary, or a transform boundary.
A convergent plate boundary is formed by tectonic plates crashing into each other. Convergent boundaries are oftensubduction zones, where the heavier plate slips under the lighter plate. Subduction zones are frequently sites of volcanoes, as the heavier plate melts back into the Earthsmantle.
