Hot Rock Plume Creates Two Volcano Chains Near Australia

A single plume of hot rock deep inside the Earth is responsible for forming two separate volcano chains off the coast of Australia. Scientists studying geological formations in the region uncovered how this deep underground heat source split or behaved in a way that produced two distinct lines of volcanoes rather than just one. This finding helps researchers better understand how volcanic chains form far away from tectonic plate edges. The study provides new details about the movement of hot material from beneath the Earth's crust and how it shapes the ocean floor over millions of years.
