The new waveforms expand the broader conversation on Earth’s mechanics. Certain aspects, like magnetic fluctuations and ...

The Earth's inner core was once liquid ... We use this information to estimate the core's temperature, assuming that the boundary between solid and liquid represents the intersection of the ...

As iron is the primary component of the Earth's core, its properties (e.g., its melting temperature at the pressures found in the proximity of the Earth's inner core boundary) set an upper limit ...

Fed by data collected from high pressure-temperature lab experiments designed to emulate conditions of Earth's inner core, the findings were then compared to seismic-wave studies of the Earth's ...

New research sheds light on the Earth's "innermost inner core," offering new insight into the formation of the planet and its magnetic field. From our morning news briefing to a weekly Good News ...

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.

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Scientists have discovered that Earth's inner core, previously thought to be solid and unchanging, has experienced significant shape changes over the past 20 years. Through advanced seismic ...

Seismic wave data previously suggested the Earth’s hot inner core is slowing its spin. Now, researchers say it’s also deforming around the edges Sara Hashemi Scientists released an update to a ...

In fact, solid iron at high temperature and pressure could ... The findings confirm that helium could stay locked in Earth's solid inner core for a long time, Olson told Live Science, but he ...
