Where the Earth’s core meets the mantle, there are two giant regions that have baffled geologists for fifty years. A new piece of the puzzle has now emerged with the discovery that they have different ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

Because of their high temperatures and positions in the deep mantle on opposite sides of the Earth, the LLVPs affect how heat leaves the Earth's core. "Heat extraction from the core will occur ...

Deep inside the mantle (the layer between Earth's iron core and its silica-dominated crust), there are vast areas beneath the Pacific Ocean and the African continent where seismic waves travel ...

A groundbreaking study reveals that the Moon has a solid inner core with a density comparable to iron, reshaping our ...

Helium is a very light gas, and most volatile gases have long since escaped the mantle, having been blown ... primordial helium is locked up in Earth's core, where it would remain safe from ...

Deep inside the mantle (the layer between Earth's iron core and its silica-dominated crust), there are vast areas beneath the Pacific Ocean and the African continent where seismic waves travel ...
