There’s an immense amount about plate tectonics that’s still a mystery. It’s a very young science and it doesn’t explain many observed geological features/phenomena. While it has revolutionized geology it’s still in its infancy as a field of study.
Here I thought the science was settled, the debate was over, nothing more to see, all that is knowable is now known about plate tectonics.
The fact is, we really don’t know jack about anything, and are only scratching the surface and that is how it will always be. The arrogance of so many scientists is mind boggling, with Richard Dawkins being the poster boy for that arrogance. I would include al gore too but he is no scientist, never has been, and never will be.
