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 ...

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

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 ...

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

The 660 km discontinuity is key. Three-dimensional models of mantle structure obtained using seismic data 3,4 indicate that some subducted slabs penetrate the lower mantle, but many are deflected ...

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 ...

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.

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 ...

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 ...

Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron ...

Exposing the secret layers of the Earth’s core The inner core, a solid iron-nickel sphere encircled by a molten outer core, is located deep within the Earth. However, according to recent research, ...
