What happens at deep-ocean trenches in an oceanic-continental subduction zone?

they occur because a big japaneese fart master sat on the ocean and made it have a bigger crack than his. the crack goes deep under the land it is pushed under and forms a barrel cave for bugs to sit in while they eat at the ground.. heheh

If three tectonic plates meet in the same place what happens?
This is called a "triple junction" and may include transform faults, ridges, or trenches. Subduction is not as straightforward as where just two plates meet. although a pair may move in the same direction relative to the third plate.
What happens when an oceanic plate digs into earths hot interior?
an volcano is formed
What happens after subduction?
trenches and hotspots are created
Explain the relationship between trenches and seafloor spreading?
1. New sea-floor is created by the upwelling of magma at mid-ocean spreading centers; old ocean floor is destroyed by subduction at deep sea trenches. 2. The area is a subduction zone. Magma from underground comes up and destroys that crust. That crust is then recycled and the magma cools and hardens. That creates new land, that creates the trenches. Seafloor spreading is in the ocean and happens with convection currents. That is the relationship between. 3. As new seafloor is formed at mid-ocean ridges, the old seafloor is pushed down into trenches at subduction zones.
What happens during a convergent boundary and what usually forms?
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.

What is it called when two plates slide one under the other?
It is known as subduction.

What happens when plates collide but no subduction occurs?
they hug each other
