The oceanic plate (sea-floor plate) is denser than the continental plate, so the oceanic plate will be pulled under the continental plate (subduction) and into the upper mantle, creating an underwater volcano.
volcanoes are caused by subduction. it could be an oceanic plate sub-ducting under a continental plate which would result in a coastal volcano or it could be an oceanic plate sub-ducting under another oceanic plate, which would result in a volcanic island.
It's because the oceanic plate is more dense than the continental plate.
oceanic plate
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.
When an oceanic plate and a continental plate collide, it forms a volcano. The oceanic plate subducts underneath the continental plate. As the oceanic plate slides underneath, a magma chamber is formed. This magma chamber is what feeds the volcano.
Volcanoes cannot be formed at a continental rift, due to the fact that a volcano cannot form between two continental plates: it normally forms when one continental plate and an oceanic plate collide. Normally, a volcano forms when one continental and one oceanic plate collides. The denser oceanic plate
Intraplate volcanism.
It is oceanic
Is a tectonic process where two plates ( an Oceanic plate and a Continental plate) collide. In Continental Arc environments the weaker oceanic plate always sub ducts under the stronger Continental plate. Most Continental arc environments lead to Volcano formation.
When the oceanic plate is subducted underneath the continental plate, the oceanic plate begins to melt. The molten material rises through the continental crust and a volcano forms.

the oceanic plate is less bouyant so it slides under the continental plate
The oceanic plate must be more dense than the continental plate for this to happen.
