________ and drifted north.
During the break-up of Pangaea, South America split off from Africa, North America split off from Eurasia and Australia split off from Antarctica and drifted north.
Explanation:
290 million years ago, the Pangaea pracontinent was formed surrounded by a huge ocean.
About 250 million years ago, collisions of tectonic plates caused earthquakes on the ocean and on the ocean floor.
The continent cracked, and then the Tethys Sea slowly split Pangaea into two continents - Laurazia and Gondwana.
Then, 163 million years ago, Gondwana split into Africa, Antarctica, Australia and South America.
These continents eventually separated from each other, creating the southern Atlantic Ocean and the Indian Ocean. Eventually, 60 million years ago, the northern part of the Atlantic Ocean slowly separated, eventually creating Europe and North America.
