Long before we use rocks for these purposes, they undergo a process known plainly as the “rock cycle”, which is a series of processes that create and transform the types of rocks within the Earth’s ...

How did the ocean form under Earth's crust? According to scientists, a rock - called 'ringwoodite' - was present 400 miles underground and had a huge supply of water which got stored in it.

Earth Science Scientists Discover Molten Layer of Rock Beneath Earth’s Crust The layer, located 100 miles below the Earth's surface, could help shed light on how the tectonic plates move.

The Earth with the upper mantle exposed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock approximately 100 miles beneath the Earth's ...

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.

Over 400 million years ago, an upwelling of hot rock from Earth's mantle wrenched apart the crust in Mongolia, creating an ocean that survived for 115 million years.
