Why Does It Get Hotter the Deeper You Go? Miners have known this for ages, literally since ancient times: the further you dig ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth’s core has been holding onto materials from the planet’s earliest days for roughly 4.5 billion years. Now, scientists ...

A new study offers an explanation for unusual chemical signatures found in some volcanic rocks.

We may finally know what triggered Earth’s inner core to freeze, helping unlock one of the planet’s longest-standing geological puzzles. The inner core is a solid ball of iron about 2,400km (1,500 ...

Earth's core: solid or liquid? Yes — we know more about distant galaxies than our own interior. Is Earth's core solid or liquid? Yes. Our planet's interior has been harder to study than the cosmos. We ...

The river of molten iron flowing 1,400 miles below the Pacific Ocean in Earth’s outer core has surprised scientists by changing direction. The observation provides new insights into the behaviour of ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

Is Earth's inner core solid or liquid? While the inner core is extremely hot, experts have known that it is solid for many years. For decades, scientists have known the inner core is solid thanks to ...

The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...
