Answer Details
The separation of ancient Gondwana land into different land masses was mainly caused by continental drift. Millions of years ago, there was a single landmass called Pangaea, which later split into two: Laurasia and Gondwana. Gondwana eventually split into South America, Africa, Australia, India, and Antarctica. This splitting was caused by the movement of tectonic plates, which gradually separated the land masses over millions of years.
