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 present-day configuration of the continents is thought to be the result of the fragmentation of a single landmass, Pangaea, that existed 200 million years ago.
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.
From the beginning The Wizard of Oz was telecast in color, although few people owned color television sets in 1956. An exception was in 1961, when CBS said that color telecasts had to be paid for by their sponsors. Those sponsoring The Wizard of Oz declined to do so, and the film was shown in black-and-white that year.
