What is the process whereby the weight of an uplift ocean ridge pushes an oceanic plate toward a subduction zone?

you don't have to know those things. It's not for your age. hahahahhahahahahaha

What often occurs where an oceanic plate pushes under a continental plate?
This usually is where and how mountains ranges are formed. Volcanism can also result from the subduction melting of the oceanic crust.
When two oceanic plates meet at a convergent boundary which plate pushes below the other plate?
The denser oceanic plates pushes below the lighter one.
When one tectonic plate pushes underneath another what kind of boundary forms?
subduction zone or continental plate
How do volcanoes form at constructive plate margins?
At constructive boundaries, magma from the earth's interior rises to the surface and forms mostly fissure volcanoes, but a few other tyopes as well, and forms new crust which pushes away older crust At destructive boundaries, in a process called subduction, an oceanic plate slides into the earth's mantle, where it melts. The molten roick then rises to the surface and fornms a chain of volcanoes, mostly stratovolcanoes, but a few of other types as well

What happens to an oceanic plate as it pushes against another plate?
When oceanic plates push against one another they cause subduction or adduction earthquakes. These plate tectonics take place on ocean floors all over the world.
When two oceanic plates meet at a convergent boundary which plate pushes below the other plate?
The denser oceanic plates pushes below the lighter one.
What happens when a plate gets subducted?
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.
What happens to an oceanic plate as it pushes against a continental plate and sinks?
The oceanic plate sinks into the mantle where it melts. This is replaced by new oceanic plate at the mid-oceanic ridge.
When an oceanic plate collides with a continental plate is the oceanic plate forced down into the mantle?
An earthquake is made. Shock waves move in all directions from that place ( which is called the focus) and then it reaches the ground. This point is called the epicenter. The earth then starts violently shaking.
What is ''slab-push structure?
It pushes hot magma up through the crust and makes volcanoes.

What is called when two plates collide and one pushes upwards?
Two plates colliding and one being pushed upwards is called subduction.
When regions of earth's surface sink down?
The earth's crust sinking in is called subduction. It is usually associated with tectonic plate movement. When one plate slides over another and pushes the other downward.
