Earth’s inner core consists of iron (Fe) alloyed with minor light elements, predominantly silicon (Si), yet the crystal structure and seismic velocities of Fe-Si alloys at inner-core conditions remain ...

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 ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other shifts at ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

Two huge masses deep within Earth may have remained stable for billions of years, surviving the powerful churn of the interior, according to an analysis of seismic waves ringing throughout the planet.
