While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history.

The Earth comprises several layers, each with distinct properties ... By watching how the earthquake waves behave inside the Earth's mantle, geophysicists can model what the Earth's innards ...

A new way of measuring structures deep inside Earth has highlighted numerous previously unknown blobs within our planet's ...

There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity.

Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron ...
