A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have ...

Located 3,000 miles below the Earth’s surface, the inner core is anchored by gravity within the molten liquid outer core.

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing ...

Scientists have always been curious about the atmosphere surrounding us, but in the past, they could not just hop on a spaceship to see what was up there. Instead, scientists hiked up high ...

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 ...
