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

Key Takeaways on Earth's Inner Core Earth's inner core is solid and blistering hot. For decades, scientists have known ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet.

The crust. The crust is the rocky outer layer where all life exists. It is between 3 and 43 miles thick. The mantle The mantle is the largest of the Earth's layers and consists of hot rocks.

In elementary school science class, we learned that the Earth has three main layers: the crust, mantle, and the core.In reality, the core—which is over 4,000 miles wide—has two layers: a ...

One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that ...

Related: Earth's layers: Exploring our planet inside and out The Earth's inner core is a hot, dense and solid ball made of iron and nickel, located 3,200 miles (5,150 kilometers) below our feet ...

The inner core is made of solid iron-nickel about 3,000 miles below the surface of the Earth. Scientists believe that the inner core’s rotation began to slow down in 2010 , but what that really ...

The inner core is the deepest of Earth’s geological layers. The crust — the layer that we live on — is just a few miles thick. Below that, filling up 84 percent of the planet, is the 1,800 ...

It is true that the outer core generates electrical currents that sustain the planet’s magnetic field, but Vidale says shifts in the Texas-size inner core are too minuscule to have an impact.

Scientists have been baffled to discover that Earth's solid inner core has changed shape.
