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 ...

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 ...

Large scale landforms at a destructive plate boundary include super volcanoes, such as the Campi Flegrei volcano in Italy - where the Eurasian plate and the African Atlantic plate are moving ...

Map of the Word with lines marking boundaries of tectonic plates. Plate tectonics is a theory that explains how Earth’s lithosphere—its upper mantle and crust—is split into sections called ...

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 ...

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 ...

Discover why Africa is slowly splitting into two continents due to the East African Rift. This geological transformation, ...

Plate tectonics, the theory that underpins Earth's geological activity, shapes our planet with mountains, shifting continents, and seismic upheavals. Yet pinpointing the origins of this ...

Plate tectonics give rise to Earth's mountain ranges, earthquakes and the long-term movement of continents, and may even have provided the right conditions for life on Earth. But as far as we know ...
