3 billion years ago, water may have been shaping Earth’s ancient volcanoes - scientists uncover a clue to how it reached the planet’s deep interior

Ancient rocks reveal water moved deep underground over three billion years ago. This process, called dripduction, occurred before modern plate tectonics developed. Water entering the mantle likely fueled magma formation and volcanic eruptions. This early interaction shaped Earth's developing continents and internal structure. The findings suggest a more dynamic early Earth than previously understood.
