Seismic waves passing through Earth's inner core have revealed much about our planet's iron center: how it's changing shape, reversing its spin, is weirdly textured, and contains an unusual state of ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...

The team analyzed borehole data from several wells using natural gamma-ray logs, core observations, and geochemical ...

Researchers find that Earth’s orbital rhythms influenced sediment and organic preservation in Jurassic shale deposits.

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 ...

The same phenomenon that causes aurorae — the magical curtains of green light often visible from the polar regions of the Earth — causes mesospheric ozone layer depletion. This depletion could have ...

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 ...

Far below your feet, nearly 1,800 miles beneath oceans and continents, Earth carries two massive scars from its violent youth. They are so large they rival continents in size, yet no human will ever ...

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 ...
