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

Earth cross section showing the classic distinction between crust, mantle and core. But new research ... [+] shows Earth's structure is far more complicated and may change over time. Analyzing an ...

Earth’s core is located below the middle layer called the mantle and the outer layer–or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer ...

At the time, scientists weren’t sure if these formations near the boundary between Earth’s mantle and core were a temporary phenomenon, or if they had existed there for millions or billions of ...

The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic core of our planet. The mantle is Earth's largest layer of rocks. However, because it is ...

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.
