.....Plate Tectonics and Landy Lemuria

Fig. 1.  Who remembers Lemuria?   Action Lady, Queen of the Continent that never was,  is about to throw the Big Switch and create the ridge displacements of the ocean floor, which will let the genie of Plate Tectonics out of the bottle.

"Geologists, like other people are susceptible to fads.  Although most geologists believe plate tectonics is an exciting theory and accept it as a working model of the earth, the theory may or may not be correct.  Most geologists today believe that plates exist and move.  But widespread belief in a theory does not make it true.  Two hundred years ago geologist "knew" that basalt crystallised out of sea water.  In the 1800s glacial deposits were thought to be deposited by Noah's flood.  Both of these incorrect ideas were finally disproved by decades of exacting field work and often bitter debate."

" Forty years ago continental drift rated only a footnote in most introductory textbooks.  Now there are many believers in continental motion and text books use it as a framework for the entire field of physical geology.  Although the idea of continental stability provided the framework for many past textbooks, today the idea that continents are fixed in position rates only a footnote as an outmoded concept.
