How do I realistically portray continental drift on my map?
I'm still fiddling with my map, and I got to thinking about continental drift. My world has two large large continents and a couple of other notable landmasses between the size of Iceland and Australia. I consciously drew the map so that the landforms fit together as if they had once been part of the same supercontinent.
My question is, when it comes to the geography, geology, plate tectonics, etc. of my world, is there anything else I might want to take account of when it comes to continental drift? That is, does the fact that these continents were once one big continent imply that they might still share certain characteristics or retain whatever traces of their previous formation? Or not really?
