Thanks for the question & for watching! Hot spot activity is often associated with continental break-ups. The break-up of Pangaea and the formation of the Atlantic ocean were likely driven by heat buildup beneath the converged mass of the super-continent, and the effects of some of that hot spot activity can be tracked through geologic time afterward. There's a good paper by Golonka and Bocharova (2000) that covers some of that geology. You can read that one for free at: www.researchgate.net/publication/222000391_Hot_spot_activity_and_the_break-up_of_Pangea

Interesting, well done video explanation. Imagine this happening over the course of tens or hundreds of years.😮

The Appalachian Chain in Alabama linked up with the Ouachita -Marathon Mountain Range that snaked across Mississippi, Arkansas, Oklahoma and Texas. Those were created when the South American plate collided with the North American plate and separated along the line of that range. They believe that the NA plate traveled over the Bermuda Hot Spot which made the Ouachita Mountains rise in elevation in Arkansas and Mississippi. Those eroded away then dropped in elevation as it moved away from the hot spot to create the Mississippi Ebayment that was filled by water from the Gulf of Mexico. I think some believe the failed Reelfoot Rift (New Madrid fault system) was created when the hot spot moved away. There's another failed rift in SE Oklahoma that's below where a mountain range was attached to the Ouachita Mountains at a right angle.
