Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.

The junction between layers of atmosphere is usually not a discreet line, but rather a transition zone where one blends into another. The change may happen over miles.

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 ...

The solid layer of Earth’s mantle lies between the crust and the core and is about 2,900 kilometers (1,802 miles) thick, making up 84% of Earth's volume and 67% of its mass.

According to NASA the upper layer of Earth's atmosphere — the exosphere — extends up to 6,200 miles (10,000 km), above which the atmosphere and space blend.

A discovery about Earth's core shows a "doughnut" shaped layer, in which earthquake waves travel slower than the rest of the core. A study published in Science Advances points to silicon and ...

Chinese scientists believe Earth's core has reversed rotation 00:47. Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a ...

But now, Professor Hrvoje TkalÄ ić, also from ANU, said new learnings about the earth’s inner core could reveal more about the planet’s past and evolution.

Scientists have known about Earth’s ozone layer for over a century, but it wasn’t until the 1970s that they grew concerned about its integrity. Early in the decade, ...
