There's a lot more to Earth than meets the eye. Far from being just a roundish rock barreling through space, our planet is composed of several layers held together by intense forces of gravity.

Therefore, drilling into the Earth’s crust assists scientists in knowing how the layers of the Earth interact, thereby developing geological studies. The Earth’s crust discovery at the ...

Planet Earth's inner core may have stopped turning and could go into reverse, according to a study published this week. Earth is formed of three layers: the crust, the mantle, and the core.

They also offer new clues to the way heat moves through Earth’s many layers. Understanding this planetary churn is an existential pursuit: Heat radiating from the planet’s solid metal core ...

the core’s rotation matched Earth’s spin. Then it slowed even more, until the core was moving backward relative to the fluid layers around it. At the time, some experts cautioned that more ...

Earth's layers: Exploring our planet inside and out — Earth's core wobbles every 8.5 years, new study suggests — Earth's solid inner core is 'surprisingly soft' thanks to hyperactive atoms ...

Of all Earth’s layers, the inner core is the most remote and mysterious. This solid sphere of iron and nickel is about 70% the size of the moon, with a radius of approximately 759 miles (1,221 ...

At the center of our planet is a very hot rotating ball of mostly iron and nickel (sorry Journey to the Center of the Earth fans). Scientists infer features of this innermost geographic layer ...

Because of its important role in the everyday function of modern society, scientists are eager to understand how disturbances in the ionosphere can impact life on Earth, and that’s why team of ...

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet that sits some 3,000 miles (4,828 kilometers) below the surface.
