Interesting idea. I never thought that the thin crust needed some push to start cycling, I figured the circulation underneath was enough since it has been going for billions of years. But let’s not forget the real MVP, because without Theria slamming into the early Earth and forming the Moon from some of the lithosphere, the crust would have been too thick for any movement regardless.

if anything i thought the opush wouldve been from asteroids/comets/planetesimals. thats why im not a scientist.
Maybe they had a part to play too. Scientists need to hurry up and end the suspense.
