Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. Researchers had previously identified ...

The interiors of rocky planets and moons tend to be pretty hot compared with their surfaces. This heat, which can be caused by a number of sources — such as tidal stretching and compression, the ...

A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth’s mantle flows beneath the ocean’s tectonic plates. The findings, published in the journal ...

Scientists have been trying to solve the mystery of why plate tectonics works the way it does for over a hundred years. And they might have just uncovered a key to cracking it. Eons is available to ...

Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. The molten layer is located about 100 ...

New findings provide a greater understanding of plate subduction, or how tectonic plates slide beneath one another. This recycling of surface materials and volatile elements deep into the Earth's ...

The speed of seismic waves can reveal the temperature of structures under Earth’s surface, with faster waves indicating cooler temperatures and slower waves, warmer ones. Unusually low wave speeds ...

The Earth with the upper mantle revealed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock in a key region just below the tectonic ...
