The very center of the planet, a solid ball of iron and nickel floating in a sea of molten rock, appears to be slowing down in relation to the movement of Earth itself. The inner core has slowed ...

Decades worth of seismic data confirms the rotation of Earth's inner core is moving slower than the planet's surface. The rotation of Earth's inner core began to slow down more than a decade ago ...

This inner core has intrigued researchers since its ... said study coauthor Dr. John Vidale, Dean’s Professor of Earth Sciences at the University of Southern California’s Dornsife College ...

as it enhances our understanding of inner core dynamics,” said Dr. Yoshi Miyazaki, an associate professor in the department ...

One minor impact, he said – which is impossible for the average person to detect – is the influence of the rotation of the inner core on the length of Earth's day, but it's only by an order of ...

EARTH'S inner core is rotating more slowly and has changed ... But the Moon's gravity tugs at the side of Earth that is closest to it, creating what are known as "tidal bulges." ...

“What we ended up discovering is evidence that the near surface of Earth’s inner core undergoes structural change,” Vidale said in a statement. The new study used seismic waveform ...

Scientists Baffled to Find Signs of Another Core Within Earth’s Inner Core, Say ‘We Have to Rewrite the Textbooks’ For decades, schoolbooks have painted a relatively simple picture of Earth ...

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 ...

The new research adds to the mysteries of the planet’s deepest interior region. By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may ...

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 ...
