The current configuration of continents is unlikely to be the last. Supercontinents have formed several times in Earth’s history, only to be split off into new continents.

Geologists have noticed that there is a quasi-regular cycle in which supercontinents form and break up every 300 to 400 million years, but exactly why is a mystery, Murphy said. But most scientists believe that the supercontinent cycle is largely driven by circulation dynamics in the mantle, according to a 2010 article in the Journal of Geodynamics.
