Earth's Inner Core Is Mysteriously Changing Shape, Study Reveals
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 acoustic waves propagate through the planetary center.
Earth's inner core is undergoing structural transformation. 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 ...
This revelation may shed light on the mystery of why the inner core's rotation appears to have been slowing down over recent years. The Earth is made up of four main structures: the outer crust ...
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 ...
The inner core of Earth may have changed shape in the past 20 years, according to a group of scientists. The inner core is usually thought to be shaped like a ball, but its edges may actually ...
The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the ...
Earth cross section showing the classic distinction between crust, mantle and core. But new research ... [+] shows Earth's structure is far more complicated and may change over time. Analyzing ...
