I would love to watch a YouTube video explaining the geology of Middle Earth and the geology science explaining why it's impossible.

Mordor is...it just doesn't work. It's a hard scrabble plain with a large inland sea bounded on 3 sides by jagged, abrupt mountains that are entirely isolated from any other ranges, and form right angles with each other...oh and the surround a cone volcano that just emerges from the ground.
Any one of these things (minus the, I repeat, NEAR PERFECT RIGHT ANGLES formed by the mountain range around Mordor) can be explained, but the conditions that lead to one preclude the other.
I don't mean this dismissively, I just think more imagination is called for. If Mordor couldn't have arisen via normal plate tectonics, then geology must work differently on Middle Earth, or there must be other magical forces at play. (If I remembered anything significant about LoTR I would suggest a more specific theory.)
This is where a lot of people get stuck. They see the enormous effort put into world-building Middle-earth and can't help but see a gaping geologic hole. Yes, geology must work differently, but how? It frustrates people to see entire languages and histories fleshed out in minute detail on one hand, but on the other "rocks just do different, bud" on the other.
His formative encounters with industrialization were the horrors of mechanized warfare in WW1, after which he retreated to the cloistered worlds of academia, religion (he was a devout Catholic), and the rural countryside of England. The perspectives and protagonists of his stories reflect that personal arc as well.
He was overtly trying to give England back a pre-modern mythology that he felt it had lost, because he felt that it was a better vehicle for introducing Christianity to children than the comparatively stark biblical stories.
What the geophillic fans wish to hear however is more akin to, "Yes, Tolkien operated within these constraints. It would be great if someone could fanfic or headcannon their way into a reasonable conclusion with the benefit of hindsight and scientific and narrative advances we've made in the meantime." It's a small gesture that opens a door rather than shuts one and provides just a bit more cognitive closure for the people who want it.
They sure are asking a lot of a fairy tale.
After THAT there was a further catastrophe as the Numenoreans, corrupted into the Dark Arts by Sauron, who was their captive, decided to wage war on the Valar, who they believed were keeping the secret of immortality from them. The Valar were in a pickle, and abdicated their powers and called on Eru to judge, because this was outside their mandate. He Atlantis'd Numenor and destroyed the majority of their people (who had turned to worshiping Morgoth) - the Numenoreans who founded Gondor and Arnor and who created the political landscape of the Third and Fourth Ages were the remnant of that fallen civilization, who were warned of the destruction of the isle of Numenor and escaped on boats.
Also it can be supposed that Mordor was a partial creation of Sauron, who fled there after the fall of Numenor as a spirit (could be wrong about that)
Note how he discusses plate tectonics and Tolkein's ignorance, having forgotten (or never realized) that plate tectonics was not taken seriously in Tolkein's time.
It includes a whole chapter on plate tectonics, the preceding theories, and how plate tectonics itself was gradually accepted. In the book, there's also a large review on other scientific problems, like where the Sun gets energy from, why the Earth has magnetic field, where does internal the heat of the Earth come from, etc. Lots of "how do we know that..." questions. A great review, highly recommend.
So he's 100% aware what status plate tectonics had in Tolkien's time. I think he also mentions that as a linguist he wasn't a geologist, and could draw the land whichever way he imagined.

It’s a no brainer that a person cannot be equally oriented both in linguistics and in geology. ... So it would be quite possible to declare an amnesty to the Professor at this place: they say, an offense undoubtedly took place, but it does not pose a particular public danger.
