From Wikipedia, the free encyclopedia.
Pangaea (pan-JEE-ə) was a supercontinent that existed … approximately 300 million years ago. 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”. 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 movement…The 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.
