Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at the heart of the planet. But new research has revealed something much more ...

Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary ...

We all grew up learning that we live on the Earth’s crust, which is just a thin layer above the mantle. Beneath that, the outer core surrounds the inner core, and… well, that’s it ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Although this inner core is white hot ... The crust is the outermost layer of the Earth. It is the familiar landscape on which we live: rocks, soil, and seabed. It ranges from about five miles ...

And the inner core is made of solid iron and nickel ... The mantle is the thickest layer of the Earth and is made of semi-solid rock that moves very slowly, like a liquid. The tectonic plates ...

Over time, Earth's interior—which is made mostly of silicate rocks and metals—differentiated into four layers. At the planet's heart lies the inner core, a solid sphere of iron and nickel that ...

Uncover the mysteries of Mars' magnetic field, generated by a molten core, unlike Earth's solid core structure.

For example: What are the four main layers of the earth? They would be the inner core, the outer core, mantle and crust. What about this one: What percentage of the Earth’s surface is covered in ...

Mars' magnetic mystery may finally have a solution—scientists now think the Red Planet’s ancient magnetic field only existed ...
