Roshar erosion drift

Question

Continuing a discussion from the comments of this video: https://www.youtube.com/watch?v=Hw7qijXKnv8

 

In order to compensate for the erosion that would occur from the highstorms, Brandon designed a system where stone could be laid down by rain. (https://wob.coppermind.net/events/161/#e4422) According to the Coppermind entry on Roshar, this results in the entire continent gradually shifting to the east, because crem builds up on the eastern side of things as highstorms travel from east to west. However, wouldn't highstorms instead push crem deposits around to the west and erode the eastern edge, shifting the continent to the west?

I'm not sure if it's an error, because of this WoB (https://wob.coppermind.net/events/80/#e5294) saying there is more crem buildup on the eastern side of mountains, implying the continent would be shifting toward rather than away from the Origin.

Yes, the crem will build up on the eastern side of things.  However, this WoB makes it clear that the erosion on the east is what's causing the continent to drift:

How did you come up with the geography on Roshar?

Brandon Sanderson (paraphrased)

The geography on Roshar was developed as a natural outgrowth of the highstorm, which was the first concept for Roshar, which was inspired by the storm of Jupiter, which was me wanting to tell a story about a world with a continual magical storm. And then I built the ecology and all of these things up from that. Roshar had to grow up--I had to find a mechanism by which stone was deposited by rain, because I felt that the constant weathering over that long of a time would leave no continents. So the crem was my kind of scientific-with-one-foot-in-magic hack on keeping the continent. So the continent does drift. They don't have plate tectonics. The continent actually moves as it gets weathered on the east and gets pushed that direction over millennia of time.

This is just an error in the Coppermind. Thank you for pointing it out

Fixed. 

Feel free to edit the Coppermind if you come across other any inaccuracies.  That's the great thing about it - everyone can participate!
