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 ...

Our Earth is structured sort of like an onion – it's one layer after another. Starting from the top down, there's the crust, which includes the surface you walk on; then farther down, the mantle, ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

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, ...

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 ...

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 ...

Earth’s atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. "The Snow Makes ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

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 ...

While this new layer is difficult to observe, its existence may point to an unknown, dramatic event in Earth's history. Investigating the structure of the inner core can help us understand more about ...
