Pangaea: The Supercontinent

 From Wikipedia, the free encyclopedia.

SOB.pangea-continental-driftPangaea (pan-JEE) was a supercontinent that existed … approximately 300 million years ago.[2] It began to break apart around 200 million years ago.   The name Pangaea is derived from Ancient Greek [words]  pan meaning “entire”, and Gaia meaning “Mother Earth”.[4] The name was coined during a 1927 symposium discussing the theory of continental drift. A scientist named Wegener postulated that, prior to breaking up and drifting to their present locations, all the continents had at one time formed a single supercontinent. Originally, this theory was rejected because it was thought that nothing could move a landmass as large as a continent. We now know that continents do move. [The movement] is called continental drift or tectonic plate movementThe break-up of Pangaea continues today in the Red Sea Rift and East African Rift.

The progression from a single supercontinent to the continents of today is shown in the pictures to the left.
