Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, ...

There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Water leaking into the Earth may be wrapping the core in crystals, a study has suggested. The study may help explain a weird area in the outer core that has long puzzled scientists. One expert said ...

Around 3,000 kilometers (1,864 miles) beneath our feet, there's a mysterious band of material called the D" layer, which has long fascinated scientists for its lumpiness. Thin in patches and thick ...

Earth's deep mantle stored enough water in rocks to equal one ocean during our planet's early molten days, helping explain ...

A new study confirms that Earth's inner core has been rotating more slowly than usual since 2010. This mysterious "backtracking" could also end up slightly altering the planet's overall rotation, ...

There is more to Earth than what we can see on the surface. Both the exterior and interior regions of the planet are made up of many layers with various properties. These layers are formed because of ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...

Particles from Earth’s atmosphere may be preserved in the Moon's soil, offering a long-term record of Earth’s atmospheric ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...
