The three types of dynamic plate boundaries are the convergent, divergent, and the transform boundaries. The Juan de Fuca microplate system consists of a subduction zone along the North American plate at both the Gorda and the Juan de Fuca plates. The system meets the Pacific plate along a divergent zone at the east most boundaries. This divergent zone is composed of three major sea mount ridges (the Gorda, Juan de Fuca, and the Explorer ridges) which feed both the Juan de Fuca microplates to the west and the Pacific plate to the east.
