Scientists Propose New Theory for How Continents Form

Published: 13 December 2022
UC San Diego geologists discovered “ridge-jump tectonics” as a fourth process forming continental roots, where expanding mid-ocean ridges overtake dying ridges, attaching buoyant rock to continents. This complements subduction and mantle plume processes.
