Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

LOS ANGELES — Scientists have just detected something unusual happening 3,000 miles beneath our feet. New research from an international study reveals that Earth’s inner core, a ball of mostly iron ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

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 ...

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 inner ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...
