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

The Earth's interior is composed of four layers ... in diameter. Although this inner core is white hot, the pressure is so high the iron cannot melt. The iron isn't pure—scientists believe ...

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 ...

USC researchers identified a six-year cycle of super- and sub-rotation in the Earth's inner core, contradicting previously accepted models that suggested it consistently rotates at a faster rate ...

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.

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have identified another possible commonality between Earth and Mars: a solid inner core.

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 ...

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 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 ...
