Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at ...

The Earth has a layered structure, including the core, mantle and crust. The crust and upper mantle are cracked into large pieces called tectonic plates. These plates move slowly, but can cause ...

G eoscientists have used earthquakes to study the composition of the lower portion of the Earth’s mantle under the Pacific ...

New research is reshaping how scientists understand the earliest days of Earth’s formation—suggesting that the deep interior ...

Full Waveform Inversion (FWI) is capable of finely characterizing the velocity structure, anisotropy, viscoelasticity, and attenuation properties of subsurface media, which provides critical ...

and the discovery suggests there could be huge amounts of helium in the Earth’s core. This could challenge long-standing ideas about the planet’s internal structure and history, and may even ...

Claims that researchers discovered previously unknown structures beneath the Pyramid of Khafre — the pyramid situated in the ...

The study of seismic waves provides evidence for the internal structure of the Earth, which cannot be observed directly. P waves are detected on the opposite side of the Earth. Refractions between ...

revealed the internal structure of these massive currents. Their findings are published today in the journal Communications Earth & Environment. "Turbidity currents are the dominant mechanism ...
