When this happens, subduction terminates along the collision zone, the trench disappears, and the continents collide, resulting in the birth of a new mountain range. ... Volcanic Island Arcs form at subduction zones...

Subduction Zone Studies ... In places these are separated by non-rigid (deforming) zones. Elsewhere plate boundaries of three types exist: divergent or spreading (e.g., mid-oceanic ridges), convergent (e.g., subduction zones), and strike-slip (e.g., the San Andreas fault zone in California or oceanic transform faults).

The subduction of the Juan de Fuca plate beneath North America changes markedly along the length of the subduction zone, notably in the angle of subduction, distribution of earthquakes, volcanism, geologic and seismic structure of the upper plate, and regional horizontal stress.

The subduction zone is the place where two lithospheric plates come together, one riding over the other. Most volcanoes on land occur parallel to and inland from the boundary between the two plates.

This process is called subduction. The slab that is forced back into the Earth usually undergoes melting when the edges get to a depth which is hot enough. (A temperature hot enough to melt lithosphere is about a thousand degrees!). This process is called "subduction".

The melted crust also releases gases of the atmosphere which had become trapped in the ground. Thus subduction of the crust helps to recycle the atmosphere!

In the immense furnace of a subduction zone, the denser plate plunges beneath its neighbor, and portions of it may be melted by the intense heat generated within the mantle, turning the solid rock of the crust into molten magma.
