The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.

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

A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation speed – it also appears to change in shape, with subtle variations appearing in the way ...

Researchers found evidence that the Earth's inner core is changing shape, suggesting unseen processes affecting its movement ...

Research reveals structural changes in the inner core's surface, indicated by differences in seismic wave pairs.

The rotation of the Earth's inner core is tied to the planet's overall rotation. Changes in the core's structure or movement can influence how fast or slow the Earth spins on its axis. Even minute ...

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans ... both the inner core’s shape and rate of rotation.

This process drives churning in the outer core, which sustains Earth’s magnetic field. Changes in the inner core’s rotation can also affect the length of our day. “Ideally, we’d like to ...
