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 ...

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.

To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine ...

Quantum mechanics? Something to do with genetics, perhaps? One discovery that ought to be on everyone's rundown is plate tectonics - the description of how the rigid outer shell of our planet (its ...

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 ...

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 ...

Liz Bonnin introduces a video clip exploring the movement of ... The clip explains how our oceans are constantly changing due to plate tectonics. The team uses eggs which they cook underwater ...

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 ...
