Divergent plate boundaries are often found on the ocean floorâ??s crust. These are the type of tectonic plates that produce volcanoes and rifts.
The tectonic plate primarily comprised of seafloor crust is the Pacific Plate.

Yes. All of Earth's crust, both on land and on the seafloor, is composed of tectonic plates.
No. Most tectonic plates that carry a continent also include a significant amount of seafloor. Some plates consist almost entirely of oceanic crust.

No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
The seafloor crust is younger than the continental crust.
Seafloor Spreading
seafloor spreading
The driving force for seafloor spreading is the movement of tectonic plates. As magma rises from the mantle to the surface at mid-ocean ridges, it creates new oceanic crust which pushes the existing plates apart, causing seafloor spreading. This process is part of the larger theory of plate tectonics.
