Science is complicated. Experts in one field may have only passing acquaintance with another, and can get things rather wrong when they step outside their comfort zone. Case in point:

Now, mind you, this wouldn’t be much of an issue – yes, a professor shouldn’t be spreading misinformation, but we all get things wrong sometimes. But this gentleman, when advised that it’s heat from the mantle that drives plate tectonics, and that said heat is the result of radioactive decay, did not say, “Whoops, my bad.” He doubled down and claimed that the Moon’s gravitational pull is still the main driving force. Considering how minuscule that tug is, there’s no way it could generate so much heat. Yet this educator seems to think the Moon is Jupiter, we’re Io, and about a dozen professional geologists taking him to school on Twitter are wrong.

Perhaps the BBC can educate him.

And then…

And there you have it.

Now that we’ve had our class with yummy Scottish accents and sweeping visuals, I believe we should indulge in a sing-song.
