Rift valleys, sea-floor spreading and mid-ocean ridge.
Subductions zones result in the formation of a trench and also volcanoes on the overriding plate
The Pacific Ocean basin is rimmed by the most subduction zones. These subduction zones form as one tectonic plate is forced beneath another, creating deep ocean trenches. The Pacific Ring of Fire, which encircles the Pacific Ocean, is known for having numerous subduction zones and is associated with high levels of seismic activity and volcanic eruptions.
Explosive volcanoes are most common at subduction zones.
Cone volcanoes which are likely to erupt explosively are found at subduction zones. Spreading zones (constructive plate boundaries) and hot spots produce quieter volcanoes because their lava is thinner. The ones at hot spots are shield volcanoes.
At the subduction zones.
Trenches are deep ocean features of subduction zones.

Volcanoes are most commonly associated with the top plate in subduction zones.

Subductions zones result in the formation of a trench and also volcanoes on the overriding plate
Subduction Zones are usually known to be part of the Destructive Plate Boundary. The changes that occur in this boundary are: Oceanic crust moves towards the continental crust, but due to the weight of the oceanic crust, the oceanic crust sinks and gets destroyed. This forms deep sea trenches and island archs with volcanoes. As the oceanic crust is forced downwards, the increase in pressure can trigger earthquakes to strike... Basically, the two plates (oceanic and continental) are associated with subduction zones.... Hope this helped ^ ^

There are active volcanoes in Korea with associated plate subduction zones.
