... However, the mantle, while deformable in the sense that modeling clay is, is hardly liquid; a careful analysis by Sir Harold Jeffreys shows that the most rapid possible drift would only amount to a mile every hundred thousand years. In addition, Wegener considered the crustal layer beneath the ocean ...
