Trenches are deep ocean features of subduction zones.
They can, though they are more dominant at subduction zones.
This forms on the plate tectonic boundaries.... particularly the convergent plate boundries.
Volcanic arcs and oceanic trenches commonly form at subduction zones.
at subduction zones
Composite volcanoes most often form near subduction zones.
subduction zones
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.
Volcanoes Form at Active Subduction Zones or in the ring of fire
they dont affect it
Both subduction zones and spreading centers.
