continental drift. noun. geology. the theory that the earth's continents move gradually over the surface of the planet on a substratum of magma.

The Wonderful Wizard of Oz is an American children's novel written by author L. Frank Baum and illustrated by W. W. Denslow, originally published by the George M. Hill Company in Chicago on May 17, 1900.
In the book The Wonderful Wizard of Oz by L. Frank Baum and the  1939 film, the Wicked Witch of the West had no name.    In the Gregory Maguire book Wicked, The Lifâ¦e and Times of the  Wicked Witch of the West, the Wicked Witch of the West was named  Elphaba (a clever manipulation of L. Frank  Baum).
