Alright. If/when we revise the tectonics or whatever, we should probably have more detailed tectonic movement, as they don't just move in cardinal directions: tectonics meet each other in three ways: convergent (towards), divergent (away), and transform (opposite directions, or the same direction) boundaries.
I know we all are probably aware of this, but I'll just explain it further and/or post the images of explanations here:
'
Convergent boundaries have
three subtypes: continental-continental, continental-oceanic, and oceanic-oceanic.
Divergent boundaries tend to form rifts and rift valleys, and volcanic island chains (like Hawaii)
Transform tends to do little beyond creating massive earthquakes.
For reference, here's a map of our tectonic plates:
You can get a good idea of which direction the plates are moving, and because of that, you can know what type of boundaries each have. With cardinal directions, you can't get that sort of information.
