Scientists have uncovered a new explanation for what powers Yellowstone and other supervolcanoes. Instead of a deep plume rising from near Earth’s core, a broad “mantle wind” may push hot rock beneath ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and ...

The illustration shows a cutaway revealing the interior of early Earth with a hot, melted layer above the boundary between the core and mantle. Scientists think some material from the core leaked into ...

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...

The core-mantle boundary (CMB) is crucial for the Earth's magnetic field and rotation. It is known that this boundary harbors complex structures, including ultralow velocity zones (ULVZs), ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
