Reimagining Earth’s History: New Study Challenges Long-Held Theories of Continent Formation

A recent study challenges traditional views on how Earth’s continents were formed, suggesting that subduction may not have been necessary. His findings propose that the melting of Earth’s crust could explain the formation of continents, casting doubt on when plate tectonics began and highlighting its impact on life’s origin.

The formation of Earth’s continents billions of years ago created a foundation for life to flourish. However, scientists remain divided on how these landmasses came into existence and whether the geological processes involved are the same as those we observe today.

A recent paper from the University of Illinois Chicago’s David Hernández Uribe in Nature Geoscience adds new information to that debate, poking holes in the leading theory of continent formation. Hernández Uribe used computer models to study the formation of magmas thought to hold clues to the origin of continents.
