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 ...

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 ...

Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind.

All of these processes result from plate tectonics, the movement of enormous chunks of Earth's crust. This movement may be why life exists here. Earth is the only known planet with plate tectonics ...

From time to time, when Earth's tectonic plates shift, the planet emits a long, slow belch of carbon dioxide. In a new ...
