The older denser plate sinks under a deep ocean trench into the mantle. Some rock above the subducting plate melts and forms magma. Since the magma is less dense than the surrounding rock, it rises toward the surface. Eventually, the magma breaks through the ocean floor, making a volcanoe.
Subduction can occur at oceanic to oceanic plate convergence or oceanic to continental plate convergence. Two plates are colliding and the more dense plate subducts under the less dense plate.

convergent boundaries
Convergent, destructive boundaries.
Plate boundaries
convergent
Convergent collision and convergent subduction. Convergent collision collides and forms mountains. Convergent subduction subducts and forms trenches.

There are 3 types convergent, divergent, and transform boundaries. Convergent collide, divergent move away, and transform boundaries occur when two boundaries pass each other horizontally. The process of subduction is associated with convergent boundaries and tectonic plates play a huge role in these types of boundaries.
Subduction boundaries
A subduction zone and a collision zone are the same place, a collision just happens earlier, when the crusts of the two plates are interacting. Later, when the crust of one plate is being forced under the crust of another plate into the mantle, it becomes a subduction zone.

Convergent Boundaries!
This forms on the plate tectonic boundaries.... particularly the convergent plate boundries.
Subduction zones form along some tectonic plate boundaries. Of the three general types of tectonic plate boundaries, we will see them form at some (but not all) of what are called convergent plate boundaries.
Subduction doesnt occur at divergent boundaries, but rather they are found at convergent boundaries.
At a convergence boundary during collision of two plates there could either be Subduction or Outcropping. Subduction occurs when the collision involves plates of different types and densities while the other happens when it involves similar plate types. Mountain ranges are formed, also Subduction Zones gives rise to Trenches.
Subduction is a process that takes place at convergent boundaries.

A subductive collision.
A continent to continent convergent boundary does not have a subduction zone.
