Which of the following tectonic plates is predominantly subducting beneath the overriding Eurasian Plate to form the Japanese island arc system?

💡 Solution & Explanation

The Japanese island arc is formed through complex convergent plate tectonics where the oceanic Pacific Plate and Philippine Sea Plate subduct beneath the overriding continental Eurasian Plate. Other tectonic interactions, such as the movement of the Nazca or Arabian plates, shape entirely different mountain ranges and rift systems across the globe. This subduction zone is responsible for frequent seismic tremors and intense volcanic activity across the region.
