Oceanic. Most of the Pacific plate is under the Pacific Ocean.
The Pacific plate is mostly oceanic lithosphere while the North American plate is mostly continental lithosphere.
It is oceanic
the oceanic plate is less bouyant so it slides under the continental plate
destuctive plate margin
Convergent oceanic-continental boundary
A mobile section of the Earth's lithosphere, either continental or oceanic.
There are two kinds of plates- continental lithosphere and oceanic lithosphere. There are many types of plate boundaries, like convergent, divergent, transform, and more. Continental lithosphere is granite and oceanic is basalt.
Upper lithosphere, containing the continental crust/plate, known as the SiAl, and the Lowwer lithosphere composed of the oceanic crust/plate also reffered to as SiMa.
Continental plates are thicker and less dense. Continental plates are mainly granitic in composition. Oceanic plates are mainly basaltic in composition. The rock of continental plates is on average, much older than the rock of the oceanic plates. The oceanic plate underlies the oceans, and the continental plate makes up the land masses. Continental plates do not subduct at convergent plate boundaries.
The Philippine Sea Plate is an oceanic tectonic plate. It is located in the western Pacific Ocean and is surrounded by the Eurasian Plate, Pacific Plate, and Caroline Plate.
All major plates contain both continental and oceanic crust except for the Pacific and Nazca plates.
It is possible to have continental and oceanic crust on the same plate. The only to this exception is with the Pacific plate which exists independently.
