Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

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 ...

They believe this is a new layer of Earth’s interior found globally. The discovery could help determine how tectonic plates move. Scientists have found Hell on Earth. Well, more accurately: Hell in ...

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 ...

The beginnings of a strange layer of molten rock deep inside the Earth may have finally been figured out by geoscientists. This layer, known as the D" layer, is about 1,900 miles underneath the ...

There is more to the Earth than what we can see on the surface. In fact, if you were able to hold the Earth in your hand and slice it in half, you'd see that it has multiple layers. But of course, the ...

Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

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 ...
