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 plates ...

About 1,800 miles beneath the surface, Earth's internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the ...

A buried wedge of stiff mantle rock might be the reason why the Himalayas and the Tibetan Plateau have stayed so high for ...

Researchers have detected a large, previously unknown structure—consisting of unusually dense, hot rock—deep inside the Earth below the Pacific Ocean. The structure, known as an ultralow-velocity zone ...

A careful analysis of the complex boundary where four tectonic plates meet reveals that one of the slabs is tearing itself apart. This process is likely part of the normal life cycle of what's known ...

Using the world's most brilliant X-ray source, scientists have for the first time peered into molten magma at conditions of the deep Earth mantle. The analysis revealed that molten basalt changes its ...

In the absence of a 6,000 km-deep hole to conduct observations, scientists hoping to learn about the internal structure of the Earth presently have few options but to monitor seismic waves. However, ...

More insights about Earth's core have arrived through some detailed examinations. A team of researchers believes that the inner core is made of two distinct layers. The finding has been explained in ...
