The Earth has a layered structure made up of the core, the mantle and the crust. Different elements are present in different parts of the Earth’s structure. The crust is made from enormous ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

Scientists of course cannot cut into Earth and directly observe its insides. Instead, their knowledge is inferred from the ...

The study analyzed decades of seismic data, including recordings of repeating earthquakes near Antarctica between 1991 and ...

We are unsure of the nature of the strange doughnut-shaped structure discovered inside the Earth's core. We thought Earth had ...

Our planet's interior is much too deep and hot to explore with probes, so scientists rely on seismic waves to understand and model its structure. Seismic waves are shock waves tha ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball ...

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 ...

Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Scientists understand the structure of our planet by analysing ... Due to no instruments existing capable of probing Earth’s inner layer, scientists used earthquakes that occur on the South ...
