The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the ...

Researchers have found evidence of changes in the structure of the Earth’s core. University of Southern California team, led ...

THE velocity of longitudinal waves in the earth increases with depth down to the core, at a depth of about 2,900 km., where there is a discontinuous drop from 13·7 km. to about 8 km. per sec.

The way the waves travel reveals what type of material they moved through, including in the inner core, and help to paint a picture of what lies beneath our feet. The new analysis looked at ...

Because scientists can't actually see the center of the Earth, they used data from seismic waves created by earthquakes to analyze its composition. "They found the innermost inner core changed the ...

one dataset of seismic waves curiously stood out from the rest," Vidale said. "Later on, I'd realize I was staring at evidence the inner core is not solid." Further, the data showed that the inner ...

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.

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.

According to a recent study, the Earth's inner core, that is a solid ball of iron and nickel, is slowing down in relation to the planet's surface. The same was confirmed by USC scientists ...
