Feb 16, 2021 at 16:27 comment added Nuclear Hoagie @John Pretty much any change that's a result of orogenic plate tectonics can be undone by erosion. If the formation of mountain ranges fits the question, I don't see why the destruction of mountain ranges doesn't fit too.
Feb 16, 2021 at 15:36 comment added John @nick012000 reread the OP, they are not looking for biome changes but mountain building and moving continents. erosion cannot do what the OP is asking for. erosion is powerful but it cannot move a continent.

Feb 15, 2021 at 16:07 comment added jcaron Erosion... And its counterpart, sedimentary deposits.
Feb 14, 2021 at 2:23 comment added John @spencer huge yes but the effect they have on the outline and position of continents is practically non-existent. the grand canyon is tiny compared to the results of the largest volcanic eruptions.

Feb 13, 2021 at 23:37 comment added Spencer @John but it happens all over the world, all the time. On aggregate, it's huge.
Feb 13, 2021 at 19:08 comment added John all those are pretty small scale on the terms of continents.
