Scientists have discovered portions of the Earth's crust sinking into the mantle beneath California's Sierra Nevada mountains. This phenomenon, occurring over millions of years, helps explain ...

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 ...

As the process continued, the descending oceanic plate functions like an anchor, dragging down the Earth's crust and forming a vast depression that has accumulated millions of years' worth of ...

It’s here that Barbara Sherwood Lollar, a hydrogeologist at the University of Toronto, journeys into the planet’s crust to hunt for signs of life. “You get into a small truck or vehicle and go down a ...

Scientists have discovered that portions of the Earth's crust are peeling away and sinking into the mantle. The geological churning is happening beneath California's Sierra Nevada mountains. The ...

Extremophiles: Life in Extreme Conditions Extremophiles are the superheroes of the microbial world. These organisms find a ...

Earth's Inner Core Is Undergoing a Transformation Feb. 10, 2025 — Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is ...

Under the southern section of the mountain range, the lithosphere —the upper part of Earth's mantle and part of the crust — has already peeled away and sunk into the deeper mantle, according ...

The Earth’s surface plays a critical role in the Earth system by interacting with the ocean and the atmosphere. To understand the Earth system, scientists must observe how the Earth’s surface changes ...

“But modeling the long-term evolution of ocean pH is a notoriously difficult problem, as it involves almost all of the components of the Earth system: the atmosphere, the ocean, the crust, and the ...

They extend nearly 1000 kilometres up from the outer core into the lower mantle, a slowly-moving layer between Earth’s crust and core. Because seismic waves pass more slowly through these ...
