Question

What happened to all the continents by the close of the Paleozoic era

Answer 1

The event that took place during the last period of the Paleozoic era was that all the continents that were present at that time joined together to form a new big supercontinent.

This supercontinent was named as Pangaea.

This was encircled by a large ocean body called as Panthalassa. The land mass at that time was very dry with harsh seasons as it was not regulated by the water bodies.
