Aurica is a possible future supercontinent . It is one of four proposed super continents that are to be formed within 200 million years ago, the others are Pangea Ultima , amasia and Novopangaea .

The Aurica Hypothesis was proposed by scientists at Geological Magazine following a study by the American Geophysical Union that linked the strength of ocean tides to the supercontinent cycle . The study found that, “When tectonic plates slide, sink, and shift the Earth's continents to form large landmasses, or supercontinents, the ocean basins open and close in tandem. When these basins change shape, they can meet shapes that amplify and intensify their tides. "

According to the Aurica Hypothesis, both the Atlantic Ocean and the Pacific Ocean will be closed and a new ocean will replace both. The hypothesis is that the Pan-Asian rift that currently runs from India to the Arctic will split Eurasia in two and form the new ocean. The current northerly movement of Australia and Antarctica will cause them to collide with eastern Eurasia and America to close the Pacific while western Eurasia and Africa will collide with America on the other side to close the Atlantic.
