A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than ...

"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 confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...

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.

Many people envision Earth’s structure as a tidy, layered system: the thin crust on the surface, the thick mantle below, and the core at the ... Plate tectonics is the theory that underlies ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

The two giant blobs — one beneath the Pacific Ocean and one beneath Africa — lie at the boundary between Earth's mantle and its outer core, some 1,900 miles (3,000 kilometers) beneath the surface.

Although this inner core is white hot, the pressure is so high ... The next layer is the mantle. Many people think of this as lava, but it's actually rock. The rock is so hot, however, that ...
