Mid-ocean ridges, volcanoes, earthquakes subduction zones, trenches are all geologic features of convergent continental-oceanic plate boundaries, like the tectonic plate boundary between the Juan de Fuca Plate and the North American Plate. Island Arcs are feature of divergent plate boundary.
Explanation:
The tectonic plate boundary between the Juan de Fuca Plate (oceanic) and North American Plate (continental) is a type of convergent continental-oceanic plate boundary.
The Juan de Fuca plate is below the North American plate and along western edge of the Cascadia subduction zone.
As the oceanic plate drifts and collides due to faulting, it cools and dives under the continental plate, and the water from the subducting slab which which melts the magma. The magma then breaks into volcanic eruptions or causes earthquakes depending upon the seismic activity and might also lead to tsunamis.
