The large convection cells within the Earth according to analysis of a model where rolls are formed with identical height and breadth. S-America and Indonesia are ‘mirrored’:
This amazing fact can be elaborated on in countless ways. Let us compare two points:
These pictures show how the coasts of S-America and Papua follow the same trend. The trend can be calculated as for horizontal forces at 0° latitude, about 12.5° compared with EW-axis. As the red arrow show, identical tectonic features appear exactly the same distance away from the division point of convection rolls at equator, marked with yellow position pin of Google map inside the red circles.
