More hypothesis
1) Pengea was the first and last supercontinent
2) Future plate tectonics animations which shows south pole plate will move upward etc..may not be correct
3) Plates whose 50%+ land mas have crossed Equator will not come to Equator again.
Suppose ,if we believe all previous supercontinents were there ,then the question remains ,what has happened to those all old plate boundaries.?
Are those merged with one another?
If yes, is there any chance of existing plate boundaries getting merged? making one bigger homogeneous plate?
For such haphazard movement of plates throughout previous supercontinents, the convection heat currents were changing all the time? if yes why
If such strong heat currents were present earlier it will not allow the last big supercontinent Pengea.
So the fact is ( as per my Opinion)
1) The Pengea was the first and last supercontinent
2) It did not move Noth or south as thland mass on both side of Equator was equal
3) The violent quakes and eruption first broken it in two pieces
4) Once broken the two plates stated moving north east ( above Equator) and Siuth west ( below Equator)
So there are no chance of South pole plates moving northward and crossing Equator
