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 ...

Both are twice the size of the moon. Those blobs, the theory goes, created plate tectonics – the geologic phenomenon that fuels earthquakes and volcanoes, which allow life to flourish.

Today, the upheavals of plate tectonics continually reshape Earth. When this began is much disputed - and we can’t fully ...

Geology’s Theory of Everything continues successfully to defend its title. ■ Curious about the world? To enjoy our ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

According to plate tectonics theory, Earth's outer shell is divided into multiple plates that slowly glide over the mantle. This slowly changes Earth's surface over time by merging, or separating ...

Just like the theory of plate tectonics is still being refined, so too will this one about how those plates first formed.

A new study rewrites the story of human evolution, suggesting that intelligent life is not rare but a natural planetary ...

The tiny Juan de Fuca plate is largely responsible for the volcanoes ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another ...

Plate tectonics is relatively new, put forth in the last 30 years or so — its forerunner was the now-discarded continental drift theory. The theory states that Earth's outer shell is made up of ...
