What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep interior ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...

There are 17 rare earth elements (REEs) in all — 15 lanthanides plus yttrium and scandium. It's a fairly diverse group, with each rare earth mineral having different applications, pricing and ...

A study published on March 24 by two researchers from Yale’s Earth and planetary sciences department adjusts the timeline of continental crust formation to start approximately 650 to 750 million years ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

Meteorite impacts can be cataclysmic events in the history of a planet, melting rock, changing atmospheric chemistry, and wreaking general havoc. In a new study published in Earth and Planetary ...

There are 17 rare earth elements on the periodic table, but a better name for them would be the "troublesome earths." Here's why. When you purchase through links on our site, we may earn an affiliate ...

Rare earth elements are critical to many industries—used in electric motors, medical imaging and diagnostics, oil and gas refining, and computer and phone screens. The 17 rare earth elements all have ...

Rare earth elements are necessary for modern technology, including green energy, but they only come from a few sources around the globe. New research has discovered them hiding in coal mines in the ...

So, it's believed that the Earth's core is mainly iron and nickel. These aren't, however, the heaviest elements in the Earth's chemistry. There are plenty of heavier elements like lead, thorium, ...

Rare earth elements (REEs) are a group of 17 metallic elements essential in many modern technologies. Despite their name, they are not actually rare, but they are difficult to extract and refine. In ...
