The first layer is the crust, a thin outer shell that extends about 18 miles (30 km) below the planet's surface. The next layer, the mantle, stretches about 1,800 miles (2,900km) below Earth's ...

The solid metal core of Earth does not rotate perfectly in time with the outer layers of the planet, and new research confirms that it has now reversed direction.

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.

The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

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 ...

Earth’s innermost layer is a 400-mile-wide ball of iron, new study suggests By Jackie Wattles, CNN 3 minute read Updated 10:35 PM EST, Tue February 21, 2023 Link Copied! This Blue ...

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.

A previously unknown layer of partially molten rock has been detected beneath Earth’s crust. The discovery could help scientists learn more about the motions of Earth’s tectonic plates.

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.
