Earth’s innermost layer is a hot, solid ball of metal surrounded by a liquid metal outer core. For decades, planetary scientists suspected that the solid inner core deformed over time as it spun.

Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the inner core was widely thought of as a solid sphere.

“What we’re observing in this study for the first time is likely the outer core disturbing the inner core,” explains Vidale. Turbulence in Earth’s molten outer core disrupts the boundary ...

The surface of Earth's inner ... that the inner core's surface, while solid, could be quite changeable over short periods. "The most likely thing is the flow in the outer core is stirring up ...

Earth’s interior is like a giant layer cake with four main layers: the crust, mantle, outer core, and inner core. The crust is the thin, outermost layer where we live, and it’s broken into massive ...

But a new study has found that its edges are softer than realized and actually changing shape as they press against the liquid iron and nickel in Earth’s outer core. “The molten outer core is ...

The new research adds to the mysteries of the planet’s deepest interior region. By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may ...

Earth's inner core may have changed shape, according to researchers studying unknown transformations deep within the planet.

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.

A new study has seen scientists unexpectedly find that the inner core of our planet is changing its physical nature ...
