The liquid outer layer of the core is responsible for producing Earth’s magnetic field, which is further stabilized by the solid inner section. [Related: The Earth’s inner core could be ...

A group of scientists has discovered a hidden layer of molten rock under the Earth’s surface. The new layer is located around 100 miles beneath the surface and appears to extend below much of ...

The mantle has a thickness of about 1,793 miles, making it Earth’s thickest layer. The thinnest and most brittle layer is the crust, however.

The layer makes up for 55% of the Earth’s volume. It contains minerals like iron, and magnesium, and silicates like ferropericlase and silicate perovskite. 7 / 8 ...

Volcanic eruptions can destroy essential infrastructure, ground air traffic for days, wipe out entire cities, disrupt the ...

Earth’s core is pretty dynamic. Its spin speeds up and slows down based on how its two primary layers are behaving. As we improve the waveform techniques used to study the deepest layer ...

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, ...

Many parts of Earth are covered and protected by a layer of organisms called a biocrust. The layer acts as a skin for the Earth, protecting landscapes and reducing long-term damage.

The ozone layer shields life on Earth. We’ll soon lose a key way to monitor its health. NASA's Aura and Canada's SCISAT near the end of missions to monitor ozone-depleting substances ...
