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.

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 ...

Scientists drilled the deepest core yet, reaching near Earth's mantle, uncovering unique geological samples and offering new ...

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 ...

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 ...

A team of geophysicists say that an enormous mass shifted deep beneath the Earth's surface 18 years ago, as spotted by NASA ...

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 ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...

In one of the great environmental success stories of our time, scientists say that a 35-year-old agreement has resulted in the steady and promising recovery of the Earth's ozone layer, a critical ...

The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens, allowing ...

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 ...
