Visiting from WorldBuilding SE. Someone recently asked a question that dusted off an old theory I had once had, so I started digging. Sadly I could find little more on the topic than the first time I had the thought so I am coming here.
I remember learning about plate tectonics in school, books, TV, magazine articles, etc. All mention the origin of the continents was quietly skipped. If it were mentioned at all it was just noted as a mystery.
Fast forward a few more years and I learn of another theory, about the formation of the moon. I read about the Theia Impact theory and saw this animation where another planetary body (Theia) impacts the Proto-Earth, forming the moon:
The moment I saw it I knew here was the origin of the continents. Perhaps not the crustal plates but the contents, or rather the cratons that float atop the mantle and form the continents we are familiar with.
Everyone knows of Gondwana and Pangaea, supercontinents of the past. More rarely known is there may have been as many as 10 supercontinents. Ur and VaalBara being among the first, billions of years before Pangaea.
Question: Have there been any publications or studies to prove my novice theory that the moon formation had something to do with the origin of the continents? I was able to find a couple references from Harvard papers, but honestly and obviously it would take a degree to decipher 90 percent of it. In which case I would be answering my own question. Even here the closest answer is that they formed in the early Hadean.
So is this an accepted theory I just haven't ran across, or has it been considered much before?
