Both segments are plateaus, but they stand at different elevations. The simplest reason for the width-rate correlation is that both increase with distance from the poles of relative rotation of the colliding plates. The plateau morphology and the height difference cannot be explained by a viscous or an elastic-plastic lithosphere. Instead, the difference in plateau height can be explained by proportionality to the total mass flow into the collision belt. The width-slip-rate relation provides a tool for estimating ancient plate motions. For example, the inferred Uralide collision rate was 5 to 9 cm/yr, with a pole of rotation at lat 81°N, long 75°E.
