The inner core of the Earth appears to hold an innermost secret. Geology textbooks almost inevitably include a cutaway diagram of the Earth showing four neatly delineated layers: a thin outer ...

It’s not hard to see why there are so many conspiracy theories about what lies beneath our feet. The surface of the Earth – the crust – on which we live makes up a mere one per cent of the planet’s ...

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

This diagram shows the different layers of Earth's interior — the solid iron-nickel inner core, the molten liquid iron-nickel outer core, the layers of the mantle, and the crust.

The newly identified molten layer is located 100 miles (161 kilometers) below the Earth’s surface. This layer is a part of the asthenosphere, which sits beneath the tectonic plates. The ...

Scientists have long wondered what lies at the center of the Earth. New research is putting weight behind a theory that our home planet has a distinct ball of iron within its metallic core.

Keep reading to learn more about Earth's different layers, its atmosphere, and what makes the "blue planet" unique. Earth is made out of different layers, and those layers get hotter and more ...

The depths of the Earth still hold many surprises. A team of scientists has discovered that objects move horizontally in the Earth's mantle, nearly 1,864 miles (3,000 km) beneath our feet.
