   • 2009 [1986], Allan Cox, Robert Brian Hart, “Absolute plate motion”, in Plate Tectonics: How It Works‎, Blackwell Scientific, →ISBN, page 355:

     For example, if two trenches remained fixed relative to the local parts of the mesosphere into which they were subducting and if these two parts of the mesosphere were moving relative to each other, then the positions of the two trenches would move in the fixed reference frame. However since on Planet B the rate of deformation of the mesosphere is much slower than the rate of plate motion, we would still be able to draw the useful conclusion that the rate at which trenches and their subducting slabs move laterally relative to the mantle is very slow.
