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 ...

New study reveals that Earth's inner core is undergoing unexpected structural changes, challenging long-held assumptions about its solidity.

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, ...

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 ...

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 Earth with the upper mantle exposed. Researchers at The University of Texas at Austin have discovered a previously unknown layer of partly molten rock approximately 100 miles beneath the Earth's ...

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 ...
