"Fractional differentiation" is the modern theory on the origin of Earth's continents.
Plate tectonics is supposedly older than continents. The story goes: subduction zones and volcanism create mountains. The sea floor migrates and piles more stuff on them. Over eons the piles get quite large. *Poof* you have continents.
"All continental crust ultimately derives from the fractional differentiation of oceanic crust over many eons. This process has been and continues today primarily as a result of the volcanism associated with subduction."

Most scientists believe that there was no continental crust originally on the Earth, but the continental crust ultimately derived from the fractional differentiation of oceanic crust over the eons. This process was primarily a result of volcanism and subduction.

I have a different perspective to share with you. The Archaic Crust Theory of continents asserts Earth's continents are what remains of protoEarth's original crust.
The story starts with protoEarth. It was a world much smaller than the one we have now. ProtoEarth had a sister planet that orbited the sun in the same orbit as protoEarth. There's a curious phenomena in orbital physics called Lagrangian points that permits multiple bodies to occupy the same orbit. Theia was the name of the other planetoid. Jupiter's gravitational influence was most likely Theia's demise. Destabilizing its orbit even a little from the Lagrangian point would mean the system would collapse and the two planetoids would eventually collide. If you're familiar with with how the moon formed then you already know some of this story. ProtoEarth and Theia did collide. Fallout from that collision is what our moon formed from.
Both protoEarth and Theia had solid crusts. All of the lightest stuff had already floated to the surface and formed solid crusts of rock that covered their entire spheres. About half of protoEarth's crust was destroyed upon impact. This wasn't a hit and run type of event. Theia didn't hit us and keep going, it mostly joined us. It is now part of the world we know today. (The fact we didn't get blown to bits has got to be one of the most remarkable cosmological coincidences the universe has ever witnessed. The tolerances on that one were so, so small.) As mentioned above, our moon is a collection of some of the fallout from that impact. Some of it was lost to space. Most of protoEarth's and Theia's mass combined to form Earth. The portion of the original crust that survived the impact is what we know as continents. We got an increase of volume when the mass of Theia joined our own. What was closer to half of protoEarth's crust wound up covering more like a third of Earth's larger surface area. There are consequences to that: If you take half an egg shell and force it to adhere to the volume of an orange, you're gonna create a few fractures. I'm guessing an original one is what separates North America from Siberia. Lake Baikal and the fault line that runs beneath the Mississippi River are also consequences of forcing bent rock into a reduced arc. A comet helped break India from Antartica.
Earth forms crust still! Earth has its own crust! As mentioned above, all the lightest stuff had already floated to the surface so the crust formed today is much more dense than the original crust. We call it sea floor and our continents float on it. Kindly a look at a sea floor map of the Indian Ocean... India left clear tracks as it migrated north, away from Antarctica. Those, the Chagos-Laccadive Plateau and the Ninetyeast Ridge, my good sir/miss, are tracks! That is unprecedented! That's what makes our continents, our world so rare: having 2 distinct types of crust. Our continents, as we have them on Earth, are unique to all known planets and moons. There is nothing out there that remotely resembles the surface structure of this planet.

Fractional Differentiation, the existing theory, makes specific assertions/implications/predictions about our planet. Let's see how these compare to Archaic Crust Theory and observation:
Where did plate tectonics come from? Modern theory states tectonics arose long after the moon collision, after the entirety of the crust was destroyed. So there's new crust. -Brand new, cohesive unfractured crust. Cool. How did it get broken? What set off all this activity? The formation of plates and source of initial fracturing is very clear in Archaic Crust Theory.
What subduction? Crust is formed at nearly uniform density. Crust at uniform density does not subduct. No subduction also means no migration. Even if an event happened to fracture the crust, individual plates would not move very far relative to another. Imagine the world's land mass was more like 95% and our oceans were more like channels, continents would move, but not far. There would be no wide sweeping action relative to another as they imply. Hence, they have no collection technique -no way to form continents. They action they say exists simply doesn't. Between planets and moons we have hundreds of celestial bodies in this solar system alone. Ours is the only one that demonstrates subduction.
Fractional differentiation claims all this stuff (our continental land masses) got swept up off the ocean crust. What stuff? Where did all THIS stuff come from? This isn't material from ocean floor crust. This stuff, the material in our continents came from somewhere else. Crusts form at uniform densities because they are composed with more or less uniform materials. If prevailing theory were correct, continent chemical composition would look a lot more like ocean floor composition. Rather, they are very distinct. Again, crusts form at uniform densities because they are made of more or less uniform materials. The "differentiation" that is imagined in the current theory is not only wrong, it's contrary to physics principals. Plus, the whole "it all just got swept over to one side" mentality is shaky to begin with. We don't see sea floor getting swept up and adding to continental crust anywhere on this planet. Only the continental crust rises and falls. If anything it's the reverse of their views: continental crust is adding to oceanic crust.
The moon formation simulations that show earth's crust being completely destroyed by the collision is contrary to physics as well. The footage looks great but the reality of the situation is a little different. The far side of the world got an earthquake and meteor shower. I'd like to see anyone try to defend the sensationalism found in the videos.
"Fractional differentiation" doesn't happen. The whole theory is, in fact, contrary to the laws of physics. Planets do not form with two distinct types of crust, one floating on another. It takes some unusual circumstances to bring that type of arrangement out. They say our moon is too big too! I bet the odds of forming such a large moon are exactly the same as getting floating crust.
Welcome to a crash course in Archaic Crust Theory! Don't bother running a search for it because no work has been published. Actually, I'm the originator of this theory and I have more important things to attend to. No telling when you might see something like this coming from "science".
