On the surface of the earth, nothing can move along a straight line, instead the plates rotate around a point on the surface. This process is already under way. When oceanic and continental plates meet, the denser oceanic plate moves under the less dense continental plate. (Newer DVD burners use so-called zoned linear velocities, or even constant angular velocity, to avoid very high rotation rates.).
