Known as stratigraphic inversion, this discovery challenges our fundamental understanding of how Earth’s layers are formed. A ...

Normally, younger rocks are deposited above older ones, forming predictable geologic layers. In the North Sea, this process ...

Scientists say they’ve detected a new, mysterious layer at the center of our home planet. The discovery could unearth more about Earth’s history. One of geology’s basic principles is that ...

A pair of seismologists documented new evidence of a fifth layer: a 400-mile-thick solid metallic ball at the center of Earth’s inner core — like the smallest figurine of a massive, planetary ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

Scientists say they have discovered a hidden new layer under the Earth's upper mantle that could help us better understand plate tectonics.

Researchers are still discovering more about the Earth's center. A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core. This ...

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.
