a region where oceanic plates sink down into the asthenosphere is called a subduction zone.
Most notable is the so-called 'Ring of Fire', an area encircling the Pacific Ocean where oceanic crustal plates are subducting under continental plates and less dense oceanic plates.

The asthenosphere has the ability to slow down seismic waves. Is not made up of earths plates that would be the lithosphere.

Tectonic plates.Tectonic plates are plates underneath Earth's surface that move very slowly. There are oceanic and continental plates. Of course, oceanic plates are plates under the ocean, and continental plates are plates underneath ground, or continents. Each of the plates carry the things above them, land or ocean. When two continental or oceanic plates collide, it causes a fold in Earth's surface, and an earthquake. Now, when a continental plate draws near and nearly collides with an oceanic plate, something called subduction occurs. Subduction is basically when the oceanic plate dips down below the continental plate, causing a trench.
The oceanic crust consists of heavier rock, mostly Basalt, so that if a oceanic plate collides with a continental plate the oceanic plate will be forced down below the continental plate, forming island arcs.continental plates are thicker than oceanic plates.

the earth is made up of different plates and all the plates are different sizes, shapes and weight. there are 2 types of plates, oceanic and continental. a mountain is formed when 2 continental plates of the same weight collide into each other, it creates a mountain and the oceanic plates underneath them are pused down.
Convergent boundary+oceanic plate=subduction because the oceanic plate is more dense causing it to subduct down back to the mantle.
