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 ...

Plate tectonics is the theory that Earth's outer layer is made up of plates, which have moved throughout Earth's history. The theory explains the how and why behind mountains, volcanoes ...

Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

Geologists have made certain assumptions about how the crust making up our planet's earliest surface formed, but a new study has found that Earth's very first protocrust was surprisingly similar to ...

Like the Earth, the moon started off with a thick layer of molten rock on its surface. Unlike the Earth, though, the moon’s surface did not cool to form tectonic plates. Instead, it has a thick crust ...

The oldest crust on Earth, known to be unchanging, is actually being altered in real time. The North American continent is ...
