Oceanic crust is usually destroyed by subduction. This occurs when one tectonic plate, typically consisting of denser oceanic crust, is forced beneath another plate, often continental crust. As the oceanic plate subducts into the mantle, it melts and is recycled, leading to geological phenomena such as volcanic activity and the formation of deep ocean trenches.
Moun Cleveland formed as a result of a subduction zone, but is not a subduction zone in and of itself. A subduction zone is a feature that forms volcanoes, not a kind of volcano.
In deep subduction areas, the predominant type of metamorphism is called "high-pressure, low-temperature" metamorphism, often referred to as blueschist facies. This occurs as oceanic crust is subjected to extreme pressures while remaining at relatively low temperatures, typically in subduction zones. The unique conditions lead to the formation of minerals such as glaucophane and lawsonite, which are indicative of this specific metamorphic environment. This process plays a crucial role in the recycling of oceanic materials back into the Earth's crust.

Over a hot spot, you would find a shield volcano, which is characterized by low viscosity lava and gentle sloping sides. Over a subduction zone, you would find a stratovolcano, which is known for its explosive eruptions due to the magma's higher viscosity from the interaction of oceanic crust melting.
Composite or stratovolcanoes typically form along subduction zones. These volcanoes are characterized by their steep-sided profile, explosive eruptions due to the presence of viscous magma, and alternating layers of lava flows and volcanic ash. Subduction zones are where one tectonic plate slides beneath another plate, leading to magma formation and volcanic activity.
Oceanic crust gets subducted into the mantle.
A subduction zone is the plate boundary where old and heavy oceanic crust sinks into the mantle. At subduction zones, oceanic crust is forced beneath another tectonic plate, typically a continental plate, due to differences in density. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.

When one plate sinks under the other, it is callled subduction, no matter what kind of plate it is. When two oceanic plates collide, they form trenches(i.e. the mariana trench). Hope this answers your question!!!
subduction
The Alishan Mountain Range in Taiwan lies on the Ring of Fire around the Pacific. The Ring of Fire is a ring of subduction zones surrounding the Pacific which are commonly associated with volcanic activity. Subduction zones are usually associated with oceanic crust (in this case the Pacific) colliding with continental crust (in this case, Asia.) While earthquakes aren't categorized directly by the zones they're associated with, you get more earthquakes and deeper earthquakes at subduction zones rather than at constructive plate boundaries (i.e. the Mid-Atlantic Ridge) which are comparatively seismically quiet. In simpler terms, the Pacific crust moving into Asia from east to west pushed up the Alishan mountains in a collisional zone - which are commonly associated with high earthquake activity.
Tuff is generally formed from volcanic ash ejected during explosive volcanic eruptions. While some tuff deposits can be found in oceanic crust areas due to subduction zone volcanism, they are more commonly associated with volcanic activity on land.
Organisms can be destroyed by ozone. These are destroyed by the UV.
