Earth's crust ranges from 5 to 70 kilometers in thickness and serves as the planet's outermost layer. This thin shell represents less than one percent of Earth's total mass, yet it's the only layer we ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...

Earth's inner layers have just got a bit more complicated, with scientists discovering a whole new inner core within the center of the planet. Research released on February 21 in the journal Nature ...

thermal characteristics (temperature changes), chemical composition, movement, and density. Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics, chemical ...

Earth’s solid inner core layer may have paused its rotation recently and started to spin in the opposite direction instead, according to a new study. The research could further the understanding of ...

There is more to Earth than what we can see on the surface. Both the exterior and interior regions of the planet are made up of many layers with various properties. These layers are formed because of ...

Researchers have detected a previously unknown layer of partially molten rock beneath Earth's crust. The discovery could help scientists learn more about the movements of Earth's tectonic plates, ...
