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 ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

Earth’s surface is constantly shifting, shaped by the slow but powerful movement of tectonic plates. While some plates have persisted for hundreds of millions of years, others have vanished, sinking ...

Now, scientists have uncovered one of these missing pieces—the Pontus plate—shedding new light on Earth’s geological past and ...

featured a global view of plate tectonics from the 1990s,” according to the release. “This new exhibit is very interactive; it has a more Great Basin focus to plate tectonics, and it shows where ...

It has vast water oceans and abundant life. But Earth is also unique because it is the only planet with plate tectonics, which shaped its geology, climate and possibly influenced the evolution of ...

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 ...
