Continents shifted during Pangaea, but how did tectonic plates change?
How did the tectonic plates change since Pangaea - were there fewer and they broke over time into the current plate formation?
Did continents change the plate they're on?
Plates break and slide/press against each other, but do they slide? Or, is the positioning of plates absolute, and their edges just "fray"? If plates shift, how does this slide affect continental drift (if at all)? How does it occur alongside continental drift? #science
