The inner core of the Earth appears to hold an innermost secret. Geology textbooks almost inevitably include a cutaway diagram of the Earth showing four neatly delineated layers: a thin outer ...

A cross section of Earth. Our planet consists of several layers: a solid inner core, a liquid outer core, the mantle, and finally, the crust. forplayday/Getty ...

This diagram shows the different layers of Earth's interior — the solid iron-nickel inner core, the molten liquid iron-nickel outer core, the layers of the mantle, and the crust.

The Earth is made up of a total of 7 layers which are- crust, lithosphere (crust and uppermost mantle), asthenosphere (upper mantle directly below the lithosphere), lower mantle, ...

Let's say we want to build a model of the sun and Earth alone. Earth has a radius of about 6,371 kilometers (3,959 miles), but let's represent this with a marble 1 centimeter in diameter.

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 ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet.
