Scientists have discovered yet another layer deep inside the core of the Earth, a new study suggests. "Traditionally we've been taught the Earth has four main layers: the crust, the mantle, the outer ...

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 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 ...

One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that suggests ...

The research into what lies deep, deep beneath our feet has yielded precious few details over the past few decades. We all grew up learning that we live on the Earth's crust, which is just a thin ...

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.

The idea that the Earth has four layers has long been considered a basic tenet of geology, taught to schoolchildren around the globe. Think of it like an onion: First there is the crust, which is ...

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 ...

Here’s what you’ll learn when you read this story: Usually, geologic layers build on one another, with younger rocks piling on top of older ones. A new study, however, shows that this process is ...
