Water-bearing subducted slabs may not dehydrate and contribute to chemical heterogeneities at the core–mantle boundary, according to high-pressure and high-temperature melting experiments.

Although this inner core ... The mantle is about 1,800 miles (2,900 kilometers) thick and appears to be divided into two layers: the upper mantle and the lower mantle. The boundary between the ...

The Earth is made of different layers: the core, mantle and ... in the mantle separate, like this, plates move apart. This is called a constructive or divergent plate boundary.

"We have known for years that these islands are located at the boundary between the Earth's core and mantle. And we see that seismic waves slow down there," Deuss said. "The waves slow down ...

Scientists found that the inner core’s structure changes as it rotates. It deforms at its border, potentially accumulating more material in some areas and less in others — almost like creating hills ...
