Supercontinents

Supercontinents

As many as six supercontinents are thought to have formed and broken up prior to Pangaea. Roughly 400 million years pass between each repetition of the supercontinent cycle, which is currently causing the Pacific Ocean to shrink until yet another supercontinent will someday be formed. The oldest supercontinent on earth is Vaalbara which formed 2.7 to 3.6 billion years ago.
