One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that ...

A gold reservoir is hidden in Earth's core and it's leaking into the mantle, says new study A new study claims that Earth is ...

Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has been the subject of fierce debate.

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

The Earth’s interior is far more complex than what we are taught in school. Instead of just three layers- crust, mantle, and core- the Earth is made up of multiple intricate layers, each with ...

The inner core is the deepest of Earth’s geological layers. The crust — the layer that we live on — is just a few miles thick. Below that, filling up 84 percent of the planet, is the 1,800 ...

The latest discoveries about the inner core have fueled vigorous disagreements among the world’s top Earth scientists and given rise to competing theories of varying credibility, Vidale says ...

Earth Science Earth’s Inner Core Has Warped Over the Past Two Decades, ... the inner core’s shape could be changing over time because of complex interactions among the Earth’s layers.

Earth’s Inner Core May Be Slowing Its Spin, Another Study Suggests New research adds evidence to the controversial idea that the hot, solid ball at the center of our planet has been reducing its ...

By tracking seismic waves from earthquakes that have passed through the Earth’s inner core along similar paths since 1964, the authors of the 2023 study found that the spin followed a 70-year cycle.

Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has been the subject of fierce debate.
