Shifting layers deep underground might explain certain fluctuations in day length ... “At first the dataset confounded me,” ...

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The Earth's interior is ... The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter. Although this inner core is white hot, the pressure is so high the iron ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Researchers had long suspected the Earth had another layer at its core, but because its composition is so similar to the layer surrounding it, the innermost inner core was hard to spot.

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.

A layer of charged particles, called the ionosphere, surrounds Earth, extending from about 50 to 400 miles above the surface of the planet. Disclaimer: AAAS and EurekAlert! are not responsible for ...

Earth's inner core appears to have another even more inner core within it. "Traditionally we've been taught the Earth has four main layers: the crust, the mantle, the outer core and the inner core ...

We all grew up learning that we live on the Earth’s crust, which is just a thin layer above the mantle. Beneath that, the outer core surrounds the inner core, and… well, that’s it ...

The diagrams show what happens when P waves and S waves pass through the Earth. S waves do not pass through the Earth's core S waves cannot ... between two different layers, there is a sudden ...

Earth’s inner core isn’t static. Waves brushing its surface show shifting patterns, suggesting a surprisingly dynamic layer deep below. More observations might uncover hidden processes.
