The Pangaea Theory

[Little Wolf]

Does anyone know what the correct spelling is: Pangaea or Pangea?



The Pangaea theory is one that states that all present continents were once together and collectively known as a 'supercontinent' called a Pangaea. The word 'Pangaea' means 'all lands' in Greek, accurately defining the way the continents were 200 millions years ago before it split up. These split-up pieces drifted slowly apart and became the way they are today. Even until now, the shape of the Earth surface is still changing, and it will be forever, as long as the mantle underneath the Earth's crust gets heated and convection currents in the magma keeps dragging the plates.
 
The Pangaea theory was treated with much skepticsm when it was first raised. But since then, there have been much evidence to support this theory.

I didn't know this was just a theory, I've always known about the countries once being joined and figured that's just how it was, I think we were even taught this in school?  I have no idea where I learnt about it now. Thanks for sharing, it is interesting.
