This video explains recent scientific findings about changes in Earth’s inner core rotation, what researchers measure, and ...

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 ...

Can a movement many feet below our feet quietly change the Earth’s rotation? Over 3,000 miles below the ground, the Earth’s inner solid core a ball of iron and nickel whose temperature is as hot as ...

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 ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Earth’s magnetic field is a dynamic system generated by turbulent motions in the liquid outer core. These convective processes, modulated by Earth's rotation, arise from complex interactions between ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...
