 And that is analogous to what happens in, you know, the Kilauea fire pit. They've got a lot of photographs of the kind of mechanism that's been proposed for the plates. We know when new material comes up, it must go someplace. Otherwise, the Earth would be expanding constantly. And then it fit in nicely. That's where the trenches are. And that's where the oceanic plates are driven down beneath the continental plates in most cases.
