Answer 2

It is true that the idea that the continents were once one large land mass called Pangaea is part of the theory of continental drift.

Step-by-step explanation:

Pangea was a unified giant continent that existed at the end of the Paleozoic world about 300-180 million years ago.

The continental drift's movements began to disintegrate Pangea 200-180 million years ago towards the end of the Triassic and the Jurassic. The breakup of Pangea began with gigantic volcanic eruptions that may have been associated with so-called hot spots on the Earth's mantle. Then, among other things, huge rupture valleys appeared between Africa and South America.

Southern Gondwana disintegrated during the Jurassic Period as Antarctica and Australia set off on their own ways. The South Atlantic expanded during the Cretaceous 130 to 65 million years ago, but the North Atlantic was still small.

135 million years ago, at the beginning of the Cretaceous, Pangea had clearly broken into Laurasia in the north, and Gondwana in the south.
