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 ...

It looks like we might have to rewrite the textbooks. What we have always known about the Earth’s inner core has changed, and researchers have provided us with new information. Scientists recently ...

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 ...

The mysterious structure of Earth and its mantle has kept scientists hooked, and they keep studying it to make new discoveries every day. The geography of Earth already felt different from what was ...

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, ...

Scientists have uncovered a vast donut-shaped structure buried thousands of miles beneath our feet. Researchers from the Australian National University used seismic waves generated by earthquakes to ...

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 ...

The interior of the Earth, like that of the other terrestrial planets, is chemically divided into layers. The Earth has an outer silicate solid crust, a highly viscous mantle, a liquid outer core that ...
