Using very long baseline interferometry, one can actually measure the
continents' motion (it amounts to an inch or so a year in most
cases).  The results support plate tectonics, not an expanding earth
(some continents are getting closer together).  I have a friend at
NASA-Goddard who is involved in this work.
