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 ...

Both are twice the size of the moon. Those blobs, the theory goes, created plate tectonics – the geologic phenomenon that fuels earthquakes and volcanoes, which allow life to flourish.

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 ...

Sinking in one place leads to plates moving apart in other places. The movement of the plates and the activity inside the Earth, is called the theory of plate tectonics.

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 ...

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

Plate tectonics, the theory that underpins Earth's geological activity, shapes our planet with mountains, shifting continents ...

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 ...

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 ...

At the East Pacific rise, which is pushing a plate into the west coast of South America, the rate is 12.6 inches (32.2 cm) per year.

The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States. The plates make up Earth's outer shell, called the lithosphere.
