The last supercontinent.

They are about the same age, actually. The Appalachians were formed as a result of the continental collisions that formed Pangaea.
No. Pangaea was formed many, many millions of years before Christ
No, the Rockies formed as a consequence of the break-up of Pangaea.
Pangaea
The supercontinent that formed at the end of the Paleozoic era is known as Pangaea. Pangaea began to break apart during the Mesozoic era, ultimately leading to the formation of the continents as we know them today.
The last super-continent is called Pangaea, which was formed about 245 million years ago. Some believe that Pangaea wasn't the first time all the continents were combined. There is evidence that there was another super-continent way before 245 million years ago that is called Rodinia (which separated for a while, then formed back together to form Pangaea, the latest super-continent).
The one mass of land known as Pangaea was formed In the Era Paleozoic, along with mountains, and land breathing animals.
The Appalachians are younger than Pangaea because they were formed during the process in which North America removed itself from Pangaea and into the west.
Yes. The Appalachians were formed by the same continental collision that created Pangaea.
The two landmasses that split from Pangaea are Laurasia and Gondwana. Laurasia eventually formed North America, Europe, and Asia, while Gondwana formed South America, Africa, Antarctica, Australia, and the Indian subcontinent.
When Pangaea first started to separate, two large landmasses formed: Laurasia in the north and Gondwana in the south.
