New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions ...

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 ...

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

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 ...

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 ...

LOS ANGELES — For decades, geophysicists believed they understood the limits of where earthquakes could occur in Earth’s interior. Then in May of 2015, a magnitude 7.9 earthquake struck at an ...

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

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