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 ...

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 ...

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 ...

Geoscientists from the University of Toronto have made a breakthrough discovery that adds new dimensions to the theory of ...

The study of Structural Geology and Tectonics concerns the deformation of the Earth's ... and have dived and drilled in thousands of meters of water to observe and take samples from active plate ...

Research in structural geology and tectonics seeks to define how and why deformation ... mountain belts and oceans, and how the history of plate motions has shaped topics as diverse as seismicity, ...

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 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 ...
