Earth's mantle may make continents rise
The continents' rise over time has been illuminated by new research that uncovers the geological processes shaping Earth's landmasses. Scientists have discovered that ancient volcanic eruptions played a critical role in forming the stable, elevated regions at the hearts of continents. These volcanic activities, occurring billions of years ago, deposited thick layers of magma that solidified and lifted the continental interiors, creating the elevated terrains we see today. The study also highlights the importance of deep Earth processes, such as mantle plumes, in sustaining these continental features over time.
Understanding how the continents have risen helps scientists grasp the broader picture of Earth's geological history and evolution. The findings emphasize the interconnectedness of surface and deep Earth processes in shaping our planet’s structure. By examining ancient rocks and the remnants of long-extinct volcanic systems, researchers are piecing together the history of continental formation, providing new insights into how Earth’s stable land masses have endured over billions of years.
