Breakthrough discovery reveals gold and precious metals are slowly leaking from Earth's core through Hawaiian volcanoes.

In a recent discovery that could change how we understand Earth’s inner layers, scientists have found signs that precious ...

Scientists Discover Two Massive Structures Deep Within Earth’s Mantle, Say It Could Be Remains of Ancient Planet For decades, ...

Since scientists started mapping Earth's inner layers with detailed seismic activity records around 40 years ago, the inner core has rotated slightly faster than the mantle and the crust.

Its spin speeds up and slows down based on how its two primary layers are behaving ... Now, scientists believe that Earth’s inner core might be less solid than we previously thought.

Scientists study the inner core to learn how Earth’s deep interior formed and how activity connects across all the planet’s subsurface layers. The mysterious region where the liquid outer core ...

By measuring the speed and interaction of the seismic waves within the Earth's layers, researchers can estimate the position and movement of the inner core. The study confirms that since around ...

Earth’s inner core was long thought to be a solid ... changing speed and direction as they encounter various layers and boundaries inside Earth. By analyzing how these waves travel through ...

In other words, the inner core’s shape could be changing over time because of complex interactions among the Earth’s layers. The researchers found that changes in seismic waves traveling ...

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 ...

“The surface of the inner core is moving around in ways we hadn’t detected and still don’t understand very well.” Earth is divided into several layers: crust, mantle, outer core, inner ...

What is increasingly clear is that the inner core is susceptible in different ways to activity in the layers of Earth that encircle it. “The mechanics are that the outer core is circulating and ...
