Think about it.


"If upwelling magma pushes its way toward the surface but does not
break through the crust, it can push up large flat areas. This magma
plume can be created, among several examples, from a melting subducted
plate. Scientists believe that this is one process that helped to
formed the Colorado Plateau. .."

Now, ..let's get this right. We know that Plate Tectonics says the
lithospheric plate (which is lighter) pushes the oceanic plate (which
is heavier) down. And now, what this guy is saying is that the down-
going (basaltic) slab then melts, and the basalt then rises and pushes
the crust up. ...And he asserts that scientists believe this.

Is there an engineer in the house, one who's been doing a bit of
reading maybe, ...who could comment on this contribution of buoyancy
to global tectonics?

(I suppose we could call it "strange buoyancy", like physicists these
days talk about "strange physics")
