About 250 million years ago, all current continents formed one supercontinent called Pangaea (from Ancient Greek, meaning "Entire Earth") surrounded by one ocean, Panthalassa ("Entire Sea").Now, Pangaea is the most recent and most well-known supercontinent, but due to ongoing continental drift, supercontinents form all the time. 600 million years ago, there was Pannotia, and 1,1 billion years ago, there was Rodinia, etc. And apparently, about 200 million years in the future, we will get a new supercontinent, when East-Asia and North-America collide.Look up supercontinent cycle on Wikipedia for more info.
Pangaea
the earths mantle and crust chating is wrong
No! pangea changed the sufaces of the earth not the shape

Pangaea
The one major ocean in the time of Pangaea has been termed as Panthalassa.

Pangaea
Earths magma moved under the crust and the continents split
the continents have broken up from the continental drift
The earth is broken up into plates. Even when the world was called Pangaea, there were still plates. The plates begin to move, however, only about 1 cm a year. This is why we now have continents. Scientists predict that a few 100 years from now, the world will look even more different. If you type in the earths tech tonic plates into wikipedia, it might help you a little more than i did.
