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 movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But ...

Does mantle convection drive plate tectonics? After the discovery of radioactivity by Marie Curie and Henri Becquerel in 1896 it became clear that the Earth's interior would be heated by radioactive ...

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 ...

Plate tectonics had arranged the world's continents into a single massive landmasses: Pangaea. Today I attempt to use my knowledge of geography to create a basic map of what this land might have ...

Geology. The presence of oceans, continents and plate tectonics on Earth is most likely the reason there is no evidence for advanced extraterrestrial civilizations, according to new research by ...

With the discovery of plate tectonics and the mapping of the earth ... Hess proved Wegener's basic idea right and clarifed the mechanism that broke the once-joined continents into the seven ...

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 ...
