Many Pangaeas

You have probably heard of Pangaea, the supercontinent that existed about 250 million years ago. It included all the present continents in one land mass.

But did you know that not only did Pangaea break up into land masses that drifted apart to form continents, but, according to an online Wikepedia article on “Pangaea:”

The breaking up and formation of supercontinents appear to be cyclical through Earth’s 4.6 billion year history.

It appears that earth’s land masses drift over the surface of the earth. I find it interesting to learn that at one time, earth’s land masses were almost all concentrated at the north and south poles with only a narrow strip of land connecting them through the equator. What a strange world that would have been!

Knowing this, it is not so far-fetched to believe that lost continents such as Atlantis and Lemuria once existed.
