oceanic plate
It's because the oceanic plate is more dense than the continental plate.
This means that the cooler, heavier oceanic plate at an oceanic to oceanic convergent boundary is forced into the mantle - under the hotter, lighter oceanic plate. OR At oceanic to continental boundary the heavier oceanic plate is forced into the mantle under the lighter continental plate.
The African plate is both oceanic and continental.
When an oceanic plate and a continental plate collide, the oceanic plate is always subducted. Oceanic plates are denser than continental plates, and they have a higher iron content. Since they are denser, oceanic plates always sink below the continental plate in the event of a collision.
It is oceanic
The Antarctic plate is Oceanic.
oceanic plate
The oceanic plate sinks into the mantle where it melts. This is replaced by new oceanic plate at the mid-oceanic ridge.

The oceanic plate must be more dense than the continental plate for this to happen.
terranes are attached to the edge of a continent
Subduction. denser oceanic plate moves under the continental plate. The oceanic plate is submerged into the mantle causing magma to rise to the surface.
