Earth’s modern continents are the fragments of a single, 300-million-year-old supercontinent called Pangaea. This vast landmass once rested on the equator, near where Africa is today. During the age of dinosaurs, tectonic forces slowly tore Pangaea apart. Now geologists predict those same forces will reassemble the pieces into a new supercontinent, named Amasia, about 100 million years in the future.
