Thick crust and wet lava around the Azores volcanoes may trace to ancient seawater stored 400 miles down and tapped by a ...

Ancient rocks in Australia suggest Earth’s tectonic plates were already moving 3.5 billion years ago, reshaping understanding ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

The Earth’s crust is constantly changing. It’s currently made of many huge rock slabs called tectonic plates—seven major ones along with many more smaller plates—that fit together like puzzle pieces ...

Stable parts of the Earth's crust may not be as immovable as previously thought. While much of the crust is affected by plate tectonic activity, certain more stable portions have remained unchanged ...

Mon., June 23, 2025 A composite image of the supernova 1E0102.2-7219 contains X-rays from Chandra (blue and purple), visible light data from VLT’s MUSE instrument (bright red), and additional data ...

Earth's surface is a turbulent place. Mountains rise, continents merge and split, and earthquakes shake the ground. All of these processes result from plate tectonics, the movement of enormous chunks ...

Like a moth in a cocoon, the metamorphosis of Earth's crust from molten goop to solid land is hidden from view, leaving scientists to guess at how the eons-long process unfolds. Using nearly four ...

In the modern world, a reliable supply of hydrogen gas is vital for the function of society. Fertilizer produced from hydrogen contributes to the food supply of half the global population, and ...

For decades, a Tibet seismic mystery pointed to missing rock beneath the plateau. A new study finds heated crust may explain ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...
