Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward ...

The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about ...

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 ...

A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have questions, though.

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 ...

4. Ask students what layer of the Earth is shown through the shell. 5. Now ask the students to squeeze their eggs gently until slight movement of the shell pieces occurs. Ask students to look for ...

This article was originally published with the title “ The Plastic Layer of the Earth's Mantle ” in Scientific American Magazine Vol. 207 No. 1 (July 1962), p. 52 doi:10.1038 ...

Crust The crust is the outer layer of the Earth on which we live. It is the thinnest layer and is between 5 and 90 km thick. Earth is divided into four layers: the inner core, the outer core ...

Precambrian time covers the vast bulk of the Earth's history, starting with the planet's creation about 4.5 billion years ago ... which are marked by different layers of sedimentary rock.

The surface of Earth's inner core appears to be dynamic, changing shape as it rotates, earthquake waves reveal.

Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron ...
