However, the forces of erosion are busy cutting them down again almost as fast as they are being raised.
In the middle of our continent are the Petermann ranges, which are the eroded remnants of a mountain chain that onve made the Himalayas look like speed bumps. Amazing thing, this planet of ours.
There's plenty of plate tectonic evolution models on the web, and watching the reconstructions from the Cretaceous onward of the rate at which india separated from australia, then rocketed northward to impact the asian plate makes me suspect that sledging is not a new phenomenon in this part of the world
