A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could be more viscous ...
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 ...
Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...
Deep beneath our feet, far below the crust and mantle, researchers now argue that matter behaves in a way that does not fit the familiar categories of solid or liquid. At the center of Earth, they say ...
Add Yahoo as a preferred source to see more of our stories on Google. A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s ...
Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Earth’s core is pretty dynamic. Its spin speeds up and slows ...
An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...
