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.

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.

A new study finds evidence that the inner core’s outer boundary has noticeably changed shape over the past few decades. “The most likely thing is the outer core is kind of tugging on the inner ...

These differences suggest 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 the ...

Earth’s core is located below the middle layer called the mantle and the outer layer–or crust. It consists of two main parts–a liquid outer core and a more solid inner core. The outer layer ...

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.

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.

These differences suggest 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 the outermost ...

Earth’s solid inner core appears to have changed shape in the past 20 years or so, according to seismic wave measurements – but the behaviour of these waves could also be explained by other ...

Until now, it was widely believed that the inner core was a dense ball of iron floating at the centre of the molten outer core. However, scientists have been baffled to discover that the inner ...
