Now, scientists have uncovered one of these missing pieces—the Pontus plate—shedding new light on Earth’s geological past and how the planet continues to evolve. The Earth’s crust is divided into ...

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 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 ...

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 ...

Gather your supplies! In this episode we will use everyday materials to learn about tectonic plates and fault lines.

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 ...

This study, published in Earth and Planetary Physics, explores the subduction thermal state, slab metamorphism, and seismic ...

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.

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 ...

Oceans are not necessarily a permanent fixture on Earth, as they are able to appear and close due to the work of plate tectonics. More specifically, subduction zones — where tectonic plates slip ...

The two main types of natural hazards are tectonic and climatic. Natural hazards can have economic, social and environmental consequences. The risks of these occurring can vary greatly.
