The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

The earth has a structure in which several layers are stacked, and is called the crust, mantle (upper mantle, lower mantle), outer core, and inner core from the outside. A new peer-reviewed journal, ...

Researchers have found evidence of changes in the structure of the Earth's core. University of Southern California team, led by Professor John Vidale, was investigating the inner core's rotation – a ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

It is known that the surface temperature of the inner core of the center of the earth, which is 96% composed of iron as a solid, is higher than the surface temperature of the sun. The reason why the ...

The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth. We use this information to estimate the core's ...

In Jules Verne's classic 1864 novel "Journey to the Center of the Earth," adventurers descend through an Icelandic volcano into a vast underground world populated by prehistoric creatures as they ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth’s inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...
