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 ...

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 ...

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

To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine ...

In a nutshell Scientists have solved the mystery of how earthquakes can occur 420 miles deep inside Earth, where extreme ...

Scientists have discovered massive structures deep inside Earth, beneath Africa and the Pacific Ocean. These structures are ...

Many geologists attribute the great variation in the temperature gradient to complex irregularities in the structure of the earth's crust. Some even maintain that the interior of the earth is cold ...

Research into these processes is the subject of geodynamics, as it is practised in Münster. With the help of complex computer models, it is possible to investigate the processes in the Earth's ...

Nobody knew what they are, and whether they are only a temporary phenomenon, or if they have been sitting there for millions ...

These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found lurking below Africa and the Pacific Ocean, entombed some 1,200 miles below the ...

This discovery was made possible through a groundbreaking technique that maps seismic waves traveling through the Earth's ...
