A section of the upper mantle and crust under the Sierra Nevada mountains is peeling away, in a process that may mimic how ...

The phenomenon has been happening for millions of years quietly beneath our feet and could shed new light on how the ...

Rivers began pumping weathered material into the sea about a billion years after Earth formed, suggesting continents may have gotten an early start.

Using nearly four decades of seismic data from stations encompassing the northern, central, and southern Sierra Nevada along California's eastern border, geologists have uncovered signs of a critical ...

At 4,000 miles long and 30–40 miles wide, the East African Rift (EAR) system is one of the geologic wonders of the world.

The processes that form continental crust from the denser basaltic rocks of the upper mantle may make the lower lithosphere ...

Scientists discovered a hidden process where Earth's crust peels away and sinks, reshaping continents over millions of years, revealing Earth's slow evolution.

Scientists have discovered evidence that California is actually peeling apart below the surface, as dense rocks under the ...

Some can be nearly as old as the solar system itself, about 4.6 billion years. Continental crust is generally higher in silica, which makes it less dense. This low density makes continents too ...
