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

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 ...

In the latter case, high temperatures and pressures lead to the reworking of the crust, affecting its composition, as well as that of the underlying mantle. Furthermore, when two continental ...

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 ...

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

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.

For geologists, a continent is a large area of thick continental crust composed of granite or similar igneous rocks, forming the continental base, in combination with metamorphic rocks ...

These movements have altered the positions and topography of the continents, contributing to the current state of the planet’s crust. While certain regions of the continental crust, known as ...

The Earth's surface is constantly reshaped by the movement of tectonic plates, which make up the continental crust on which ...

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...
