it's entirely the case that pangaea, shifting plate theory, while introduced in 1915, was not even beginning to be accepted until the 1950s and then not necc part of any curriculum in the late 1960s, early 1970s, when i would have been in those grades.

continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea. Alfred Wegener first supported continental drift.
Wegener’s explanation of continental drift in 1912 was that drifting occurred because of the earth’s rotation. This explanation and his theory were not widely accepted. Prior to Wegener, however, many had noted that the shapes of the continents seem to fit together, suggesting some schism in the past.
Before the 1950s, the concept of the continental drift, for the most part, was not even entertained as plausible. In the 1950s and the years that followed, however, geologists began to consider the theory, and in the 1960s, most geologists came to accept that the theory may well be possible.
Most scientists, and those not believing in creationism, accept the continental drift theory, along with the theory of plate tectonics. Those endorsing the theory of intelligent design usually accept continental drift as well, but assert that a spiritual presence designed and created the earth.
Continental drift theory is now taught as accepted theory in public schools throughout the US.
