A volcano has erupted remnants of Earth's primordial magma ocean

Scientists have discovered remnants of Earth's ancient magma ocean in magma from a young volcano in the Indian Ocean, providing a rare glimpse into our planet's primordial state. This discovery is significant because it offers direct evidence of a global magma ocean that once covered Earth, which later solidified as the planet cooled. Understanding this ancient event helps scientists piece together the history of Earth's formation and evolution, potentially shedding light on the conditions that led to the formation of continents and the development of the current geological landscape.
