What has the Power to Move Continents

Before I make my inference, I just want to clarify some facts. We know that the ridges (mountains) in the ocean are constantly sprouting new rock. The rock is getting older the further away it gets from the ridge, which means that some how or another, that rock is moving. My inference is the magma or lava (once it comes up into the ocean) is the fuel that moves the continent. The lava is moving the rock in the ocean. As new rock is forcing it’s way into the world, older rock is being forced away from the ridges. If it is forcing the rock to move away, then the rock in turn must be slowly pushing against the continents. Even if the rock is being moved around the continents, some rock must be pushing against it at some point of time. Causing it to move in microscopic amounts every day or so.

However, like all good theories, this should create some interesting questions. I only have one real question about my theory and I have come up with three possibilities. Seeing how you are saying that the continents mirror the affects that are happening on old rocks, will they eventually go back into the earth?

The answer to that question is quite simple.  I’m not sure. There are two different speculations I have. The continents are such huge landmasses, that they are being pushed on all sides by ridges. They must also be pushed on all sides by trenches. They are slowly moving because they are still closer to some than the others, or their outtake of lava is stronger than other ridges. The only thing is that some time, the continents would stop moving as they reach a point of equilibrium with all the mountains and ridges. My second speculation is that yes, eventually, the continents will fall slowly into several different ridges. Their will be huge earthquakes and volcanoes and tsunamis as we get closer to the magma underneath. It will be called oblivion. However, as a huge amount of rock goes in, A huge amount of lava must come out to create another continent, similar in size.
