Not only is Earth's inner core spinning and growing, but it's also changing shape, according to new research. Our planet's ...

The Earth's inner core, long considered a solid and stable sphere, may be quite different. A recent study suggests that its surface is undergoing structural transformations, challenging our ...

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 ...

Physicists suggest a new explanation for the interesting properties of the Earth's inner core. Credit: NASA / Getty Images According to a new "holy grail" scientific discovery, the blazing-hot ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

USC researchers identified a six-year cycle of super- and sub-rotation in the Earth's inner core, contradicting previously accepted models that suggested it consistently rotates at a faster rate ...

The Earth's interior is composed of four layers ... in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe ...

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

The outer core is liquid iron and nickel and generates the Earth's magnetic field. And the inner core is made of solid iron and nickel. The surface of the earth is constantly changing. It's the ...
