Tiny zircon crystals are revealing that Earth’s earliest history may have included surprisingly complex tectonic activity.

What may look like a single volcanic eruption is usually the visible outcome of far more complicated activity taking place underground. Beneath the surface, magma can migrate, cool, mix, and ...

When referred to as a gas, it means a volatile has transitioned into the vapor phase. The most common gases (or vapor phase volatiles) emitted at the surface are water (H2O), carbon dioxide (CO2), and ...

A new scientific revelation reveals that deep in the Earth’s core lies a good amount of hydrogen as well as a large amount of iron. While the iron in the core has always been recognized as dominant, ...

Research shows Mars volcanoes erupted as recently as 50 million years ago, with underground magma chambers that cooked for 9 million years.

All around the world, from the Red Sea to the deep ocean ridges of the Atlantic, lurk more than a dozen geological misfits.

It turns out that continental breakups are just as messy as human ones, with the events leaving fragments scattered far from home ...

Most of the time, the shape of Earth’s magnetic field is quite similar to that which would be produced by a bar magnet ...

Italian carmaker Maserati presented this weekend during the I.C.E. St. Moritz a special version of the MCPura Cielo called ...

Most volcanoes form at the boundaries of Earth's tectonic plates, which are huge slabs of crust and upper mantle that fit together like puzzle pieces. Think of these plates as massive rafts floating ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...
